Embodiment Construction

[0029] In order to simplify the description, the same components are associated with the same reference numerals.

[0030] To illustrate the invention, figure 1 The architecture of an embedded system comprising such as a mobile phone (not shown) in combination with a card CARD is shown. In our implementation example, a SIM card is used.

[0031] In our illustrated example, the embedded system communicates with a data processing device, such as a server SERV, via the telecommunication network RES.

[0032] In our example, the operator OP manages various cards distributed over the network. In particular, the operator manages the accounts of various users. Typically, during card personalization, the operator assigns a pair of data items, namely a key Ki and an IMSI code associated with at least one authentication algorithm, and loads them into the card. Thus, the card stores a pair of IMSI / Ki for each user. The pair is also stored in the Authentication Center AuC.

Abstract

The authentication algorithm operates between a SIM card (CARD) and a server (SERV) which both store a subscriber identifier (IMSI1) associated with an authentication algorithm (Algo1). In a preliminary stage a second inactive authentication algorithm (Algo2) is stored. The first algorithm is then swapped with the second, so that the first algorithm is inhibited and the second activated.

Description

technical field [0001] The invention relates to a method for updating an authentication algorithm in a computer system. [0002] The invention is applicable to any data processing device storing an authentication algorithm. The invention is particularly applicable to smart cards. [0003] Smart cards can be integrated with any system, embedded or not. [0004] The invention can be implemented in various types of telecommunication networks such as GSM (Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications Service), GPRS (General Packet Radio Service), etc. [0005] The example chosen to illustrate the invention will be that of a mobile telephone combined with a SIM (Subscriber Identity Module) smart card. Background technique [0006] In order to manage a user roaming in a GSM (Global System for Mobile Communications) network, the user must be clearly identified. [0007] Because wireless channels are used, communications are vulnerable to ea...
