Embodiment Construction

[0026] FIG. 1 shows at 10 the general structure of the third generation digital mobile telephone system. In FIG. 1 , a radio mast 12 is connected to a base station 14 , which in turn is controlled by a base station controller 16 . The mobile communication device 18 shown communicates bidirectionally with the base station 14 via a radio or air interface 20, which is the Um interface in GSM (Global System for Mobile Communications) networks and GPRS (General Packet Radio Service) networks, and in CDMA2000 and W -Un interface in CDMA network. Generally, at any one time multiple mobile devices 18 are associated with a given base station that includes multiple radio transceivers to serve these devices.

[0027] Base station controller 16 is coupled to a mobile switching center (MSC) 22 along with a number of other base station controllers (not shown). A plurality of such MSCs are coupled to a gateway MSC (GMSC) 24 which connects the mobile telephone network with a public switched...

Abstract

A method of establishing a secure communications link between a mobile terminal and a server, the method comprising retrieving from storage, in the mobile terminal a prime number, p, and generator, g, for a Diffie-Hellman key exchange protocol, generating a positive integer b at the terminal, sending a message including the value of (g<=[b] mod p) from the terminal to the server, determining a shared secret number for the terminal and the server by calculating the value of g<=[ab] mod p, where a is a positive integer, using b and a public value for the server y=g<=[a] mod p at the terminal, and using a, b, g and p at the server, and using the shared secret number to establish the secure communications between the terminal and the server. The method facilitates download of software to a mobile communications system terminal.

Description

technical field [0001] The present invention relates generally to secure communication links for data transmission and, more particularly, to data communication links using asymmetric cryptography to establish a secure link using symmetric cryptography. Background technique [0002] In mobile telephony networks, data transmission is becoming more and more important, especially with regard to standards and technical specifications as devised by the Third Generation Partnership Project (3GPP, 3GPP2) (available at www. This becomes especially important for the so-called 2.5G and 3G (third generation) networks described in .3gpp.org and incorporated herein by reference). [0003] Secure data transmission is important for m-commerce, but in addition, for multimedia entertainment, telemedicine (telle-medicine), upgrade of programmable mobile terminals, upgrade of different wireless standards, etc. It is also important to download and install on the mobile terminal. Reconfigurabl...
