Abstract

The present invention provides for a host web server (210) to encrypt and transmit information to a mobile client (240) such that the decrypted clear information (220) at no time exists in a third party WAP server (230) used at an intermediate point in the transmission to the mobile client (240). This is done by the web server (210) providing two or three or more layers of encryption prior to the SSL level of encryption of the clear information (220). Therefore, when the WAP server (230) decrypts the SSL level of encryption and encrypts the result by the WTLS protocol, then no clear information (220) exists in the WAP Server (230).

Description

WIRELESS ENCRYPTION APPARATUS AND METHOD
Field of the Invention The present invention involves wireless communication. More specifically, the present invention involves wireless encryption apparatus, methods, and architecture.
Background of the Invention
Wireless communication is known. To provide security for wireless communication, various encryption schemes have been developed. More recently attempts have been made to provide a encrypted security scheme for popular acceptance that would allow web-enabled mobile phones to communicate with a host web server in a secure, encrypted manner.
The Wireless Application Protocol ("WAP") has been developed. Attempts have been made to develop a popular acceptable system using WAP for secure encrypted communications between a host web server and a web-enabled mobile phone, or other mobile client. However, to date these efforts have not met with popular acceptance because of a critical failure in the existing attempts.
Figure 1 describes the prior art and its problem. A host web server 110 contains clear information in a template format 120 which may include, for example, an address field, a name field, a content field, and any other content field. (Herein "clear information" refers to the underlying unencrypted information either before or after transmission.) The web host server
110 may be operated, for example, by a bank 170. In the prior art, the clear information 120 to be transmitted to the mobile client 140 is first encrypted at the host web server according to the SSL (secure socket layer) encryption standard. This encryption standard results in an encrypted message with no format 121 which is then transmitted to a WAP server 130. This transmission is made over the Internet 150 in . a secure encrypted manner. The WAP server 130 receives the encrypted message 121 through the Internet 150 and then decrypts the SSL encryption, yielding decrypted clear information 120, in the WAP server 130. The WAP server then encrypts the clear decoded information 120 using the WTLS (Wireless Transport Layer Security) protocol. The WTLS encrypted information is then transmitted by a wireless infrastructure to the mobile client 140. The wireless transmission is a secure wireless transmission 160 in a WTLS encrypted format. The mobile client 140 decrypts the WTLS encrypted message, yielding clear information in its template 120 in the mobile client 140.
The WAP server 130 may, for example, be operated by a telephone company ("teleco") 131. The mobile client 140 may be a web-enabled mobile phone, or other portable wireless web-enabled device.
Infrastructure for this prior art approach has been heavily invested in by various industrial players, but it has not received wide acceptance. This has not received wide acceptance because the decoded clear information 120 exists in the WAP server 130, which is owned, operated and controlled by a third party operator, which may be a teleco 131 or other company. This decoded clear information 120 exists in the WAP server 130 after the decryption of the SSL layer of the message received by the WAP server 130 from the host web server 110, and before the WTLS encryption of the clear information 120 by the WAP server prior to wireless transmission 160 to the mobile client 140. This allows the WAP server 130 and its operator 131 to read, copy, manipulate and exploit the clear information 120, perhaps without the knowledge of the web host server 110 operator 170.
This is a prohibitive issue for many potential users with host web servers 110 such as banks 170, because they are unwilling to let a WAP server operator 131 review all their most confidential client information 120. This is particularly aggravated by the potential for the WAP server operator 131 to be in direct competition with the host web server operator 170. For example, the host web server operator 170 may be a bank, whereas the WAP server operator 131 may be a telephone company with a wholly owned bank subsidiary in direct competition with the host web server operator 170.
In Figure 1, when the direction of the communication is reversed from the mobile client 140 to the web host server 110, the same problem of the clear information 120 in the WAP server 130 applies.
The same situation may also be prohibitive for the user of the mobile client 140 that does not want their personal decrypted information 120 intercepted by a third party 131.
Therefore, there is a frustrated need to provide, using the existing new WAP infrastructure, a method and apparatus for secure transmission from a host web server 110 to a mobile wireless client 140 in a secure encrypted manner that does not provide for the decrypted clear information 120 to exist at any instant in the WAP server 130 operated by a third party 131 and potential competitor with the host web server 170.
Therefore it is an object of the present invention to provide an apparatus and method for secure transmission from a host web server 110 to a mobile wireless client 140 in a secure encrypted manner that does not provide for the decrypted clear information 120 to exist at any instant in the WAP server 130 operated by a third party 131 and potential competitor with the host web server 170.
Summary of the Invention The present invention provides for a host web server 210 to encrypt and transmit information to a mobile client 240 such that the decrypted clear information 220 at no time exists in a third party WAP server 230 used at an intermediate point in the transmission to the mobile client 240. This is done by the web server 210 providing two or three or more layers of encryption prior to the SSL level of encryption of the clear information 220. Therefore, when the WAP server 230 decrypts the SSL layer of encryption and encrypts the result by the WTLS protocol, then no clear information 220 exists in the WAP server 230. For example, the host web server 210 may use ECC (elliptical curve cryptography) to encrypt the clear information 220 prior to the SSL encryption and transmission to the WAP server 230. The mobile client 240 would then receive a transmission, decrypt the WTLS encryption layer, then decrypt the ECC encryption layer to yield the clear information 220.
In an alternative embodiment, the web server may encrypt two layers of ECC before the SSL encryption and transmission to the WAP server. Then, the mobile client would decrypt the WTLS layer, and the ECC level two encryption, and a smart card within the mobile client would decrypt the ECC level one encryption, to yield the clear information 320 in the smart card 341 inside the mobile client 340. In this way, the clear information 320 would exist only in the web server 310, and the smart card 341. The clear information 320 would not exist in the WAP server 330 or in the mobile client 340 (which mobile client 340 in itself may be controllable and accessible by a third party wireless telephone company.) Brief Description of the Drawings
Figure 1 shows the prior art architecture for encrypted web-enable transmission to a mobile client using WAP. Figure 2 shows a representation of the present invention using a single layer of encryption in addition to the SSL layer of encryption.
Figure 3 shows an alternative embodiment of the present invention using two levels of encryption in addition to the SSL level of encryption.
Detailed Description of the Preferred Embodiments
Figure 2 shows a representation of the present invention. The web host server 210 contains clear information 220. The clear information is encrypted, in the preferred embodiment using elliptical curve encryption ("ECC"), yielding ECC encrypted information 221. The ECC encrypted information 221 is then SSL encrypted and transmitted as a secure Internet transmission 250 to a WAP server 230. The WAP server 230 decrypts the SSL layer yielding the ECC encrypted information 221. The WAP server 230 then encrypts using WTLS (Wireless Transmission Layer Security) the ECC encrypted information 221, and transmits the ECC WTLS encrypted information as a secure wireless 260 transmission to the mobile client 240. The mobile client 240 then decrypt the WTLS encryption layer of the transmitted information yielding the ECC encrypted information 221. The mobile client 240 then decrypts the ECC layer of encryption yielding the clear information 220 in the mobile client 240.
The problem of clear code 120 is the WAP server 130, is also found when the process is reversed for communication from the mobile client 140 to the host web server 110. The present invention also applies to this reverse problem, when the invention process is repeated and reversed for communication from the mobile client 240 through the WAP server 230 to the host web server 210. That is, the clear coded 220 in the mobile client 240 is encrypted using ECC to yield ECC encrypted information 221. This is then encrypted using WTLS and transmitted a secure wireless transmission 260 to the WAP server 230. The WAP server 230 then decrypts WTLS layer of encryption to yield ECC encrypted information 221. The ECC encrypted information 221 is then encrypted by the WAP server 230 to yield according to the SSL protocol to yield ECC/SSL encrypted information. This is transmitted in a secure Internet transmission 250 to the host web server 210. The host web server 210 then decrypts the SSL layer of encryption to yield ECC encrypted information 221. The host web server 210 then decrypts this to yield clear information 220 in the host web server 210.
Figure 3 shows an alternative embodiment of the present invention using additional layers of encryption. The host web server 310 containing clear information 320 encrypts the clear information 320 (preferably using the ECC method in the preferred embodiment), yielding the ECC encrypted level one information 322. This information is given another layer of ECC encryption yielding ECC encrypted information level two 323. The ECC level two encryption is then encrypted according to the SSL protocol protocol and transmitted to the WAP server 330. The ECC level two SSL encrypted information is transmitted in a secure Internet transmission 331 to the WAP server 330. The WAP server 330 then decrypts the SSL level of encryption yielding the ECC encryption level two information. This information is then encrypted according to the WTLS protocol to yield ECC level two/WTLS encrypted information which is transmitted to the mobile client 340 in a secure wireless transmission 342. The mobile client 340 then decrypts the WTLS layer of encryption yielding the ECC level two information 323. The mobile client 340 then decrypts the ECC level to information 323 yielding ECC level one information 324. The mobile client 340 then transmits the ECC level one information 324 to a smart card 341 attached to or inserted in the mobile client 340. The smart card 341 then decrypts the ECC level one information yielding the clear information 320. The smart card 341 in the preferred embodiment is part of a smart card system. Smart cards are referred to and described in Australian Provisional Application AUPQ8774, filed June 22, 2000 for Electronic Recordal of Currency and accessing or switching the different SIM cards or smart cards is described in PCT Publication WO 00/11624 and South African Patent 97/0097 (1997) incorporated herein entirely by this reference.
The alternative embodiment of Fig. 3 also applies for the reverse process of transmission from the smart card 341 to the mobile client 340 to the WAP server 330 to the host web server 310. That is, the clear information 320 in the smart card 341 is encrypted using ECC to obtain ECC level 1 encrypted information 324. This is then transmitted to the mobile client 340 where the ECC level 1 information 324 is received. This information is encrypted using ECC to obtain ECC level 2 information 323. This is then encrypted using WTLS and transmitted in a secure wireless transmission 342 to the WAP server 330. The WAP 330 decrypts the WTLS layer yielding ECC encrypted level 2 information 323. This is encrypted with SSL to yield ECC level 2/SSL encrypted information, which is transmitted in a secure Internet transmission 331 to the host web server 310. The host web server 310 decrypts the SSL layer yielding ECC encrypted level 2 information 323. This is then decrypted with ECC yielding ECC encrypted level 1 information 322. This is then decrypted using ECC, yielding clear information 320 in the host web server 310. The mobile client 240, 340 may be a web-enabled phone, PDA (personal digital assistant), palm pilot, personal PC, laptop PC with wireless modem, or any other mobile communication device.
The Funge system with the smart card 341 described herein contemplates a mobile phone 340, or PDAs or other mobile unit 340 with a smart card 341 inserted, with enabling features incorporated on the smart card 341. The smart card 341 is adapted to be used in the cover of the battery compartment of the mobile unit 340. The cover has one or two slots to insert a smart card 341 and the cover has contacts and circuitry to screen and connect the smart card 341 with a mobile unit 340. The SSL encryption/decryption method can be a strong 124 bit key encryption by a mainframe machine or the web server 110. The mobile device 240, 340 is a thin client that may do a less robust decryption, for example a 64 bit or 8 bit key decryption. The smart card 341 may be the thinnest client in the system with the weakest decryption. However, the mobile device 340 and the smart card 341 would be harder to eavesdrop on than the wireless transmission 342, and would therefore require a less robust encryption.
In an alternative embodiment, the smart card 341 may be any alternative encryption/decryption enabled device. The preferred embodiments describe SSL transmission over the Internet, but any transmission security protocol can be used in place of the SSL, and any telecom transmission system other than the Internet may be used. The preferred embodiment describes the WTLS protocol and wireless transmission, but in its place any other transmission security protocol may be used and any other communication link may be used in place of the wireless transmission. The preferred embodiment describes a WAP server using the WTLS protocol, in its place any other transmission protocol server may be used.
The transmission information contemplated in the preferred embodiment is information from a web server to a web-enabled mobile phone, but any other type of transmission may be used, for example SMS (short message system), FTP, or otherwise. If SMS is used then an SMS gateway server would be used in place of a WAP server.
In the preferred embodiment a mobile client 240, 340 may be thought of as a "thin" client communicating with the host web server 210, 310.
In one preferred embodiment of the present invention by Funge Systems, Inc., the Elliptical Curve Cryptography (ECC) is provided by the Certicom Corporation One Pass Protocol. Certicom SSL Plus and Certicom Security Builder tool kits are also used for the security and encryption features. Certicom's WTLS Plus tool kit is also used to implement the WAP portions of the invention in a preferred embodiment using the WAP Identity Module (WIM) standard. One preferred embodiment of the present invention uses an embedded version of Certicom's ECC 5 enabled Security Builder 6, and release 7 of Certicom's One Past Protocol (OPP7). The Certicom Corporation is located in Toronto, Ontario Canada.
An alternative embodiment of the present invention uses the Realm Secure Vector Protocol (RSVP) One Time Password (OTP) system. RSVP is provided by Real Technology, Inc. The RSVP server model used in a preferred embodiment is RSVP Fortress Server 12 and provides 128 bit encryption.
In the preferred embodiment, the ECC (elliptical curve cryptography) technique is described. However, any alternative encryption methods that are applicable could be, used, such as those by RSA, Inc., or AES, or others. The preferred embodiments shown in Figures 2 and 3 show alternately one or two layers of encryption before the SSL protocol level of encryption. However, any number of additional levels of encryption may be added for specific purposes and decrypted by one or more additional units attached to the mobile client 240, 340 in addition to the smart card 341 or other .devices.
The embodiments described herein are merely illustrative of the principles of this invention. Other arrangements and advantages may be devised by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, the invention should be deemed not to be limited to the above detailed description but only by the spirit and scope of the claims which follow, and their equivalents.
