Title: Method for determining temporary mobile identifiers and managing use thereof
Inventor: PATEL SARVAR
IPC: G06F21/62
Filed: 1999-07-02
Abstract: In the method for managing the use of temporary mobile identifiers (TIDs), the mobile and the network each store a list of TIDs for the mobile. Newly determined TIDs are added to the respective TID list such that the TIDs are stored in chronological order. To determine a new TID, the network sends a first challenge to the mobile and the mobile sends a second challenge to the network as part of a TID update protocol. The network and the mobile then determine the new TID based on the first and second challenges. As communication between the mobile and the network continues, the respective TID lists are updated. Namely, when either the network or the mobile confirms a TID, the TIDs older than the confirmed TID are deleted from the TID list. In communicating with one another, the mobile will use the oldest TID on its TID list, while the network will use the newest TID on its TID list.

Patent CA-2283208-A1 (CA)
Title: Method and device for encryption
Inventor: WOLFENSTETTER KLAUS-DIETER
IPC: H04L9/18
Filed: 1998-03-11
Abstract: The invention relates to an economical method and device for implementing even high-performance encryption functions in an encoder consisting of only a PC, software device or similar or any preferred terminal or information system, with an integrated Vernam cipher which does not need to be supported by expensive crypto-hardware for the necessary encryption process. The crypto-hardware consists of either a chip card or a multi-functional PC interface adapter (PCMCIA module) with built-in special crypto-hardware. The encryptor is simply a conventional PC, a software device or another terminal which requires no crypto-technology other than the very simple Vernam cipher (for example, EXOR), even for wideband applications in software. The external crypto-modules all contain complex crypto-functions which produce the Vernam key in reserve. These reserves are temporarily stored in an intermediate memory and then used up progressively by the encryption process through logical operations. Said memory can be installed in either the PC/terminal or in the crypto-module. The encoder always operates with the same Vernam cipher, even if the external crypto- or PCMCIA modules use different symmetrical and asymmetrical ciphers. External crypto-modules in the form of chip cards or PCMCIA modules are economical to produce. All of the complex crypto-functions are outside of the encryptor. They can be interchanged by module and can be performed in the inexpensive and somewhat slower crypto-modules suggested by the invention.
