    摘要: The terminal and the user module are authenticated in a combined manner on the basis of an authentication key calculated on the one hand by the terminal and on the other hand by the network. A session key is firstly calculated by the user module on the basis of a secret user key, of a terminal identification parameter and of a first random number. Calculation of the authentication key by the terminal involves this session key calculated by the user module, a secret terminal identification key and a second random number. The network calculates in the same way the session key and the authentication key by retrieving the secret keys on the basis of the identification parameters transmitted by the terminal. The terminals can then be authenticated by the network independently of the associated user modules.

    摘要: A process for the dissimulation of concealment of a secret code in a data authentication device by encrypting the secret code by an encrypting function for forming an image of the secret code and storing the secret code image in the authentication device. Beforehand, an encrypting function is chosen such that with each stored secret code image corresponds a plurality of antecedent codes all differing from the secret code, but which, once encrypted by the encrypting function have an image identical to that of the secret code. The secret code of a user has an authentication device in which is stored the secret code image.

    摘要: A system for control of access by messages to computer machines which are connected in a host private network by at least one private terminal that comprises an access control module interconnected at each input-output point of the host private network, each module allowing the selective transmission by inhibition, free or conditional authorization of the transmission of the messages to the host private network. A centralized supervisor module is associated with the host private network and interconnected by a specialized link to each access control module, allowing thus to control the selective transmission of the messages by each access control module.

    摘要: A process is provided for authentication in a data processing system using a data processing terminal having a programmable memory. The terminal supplies to a server an identify code (ID), the server checks the identify code, and in the case of agreement, supplies a random number (ALEA-A) to the terminal. The terminal encodes the random number using a signature algorithm (B) defined by a secret key (SID), and supplies a first signed random number (ALEA-S) to the server, which applies a signature checking algorithm (T, B, C) to the number (ALEA-S). The identity code and an encrypted secret key (KID) are written into the memory. The secret key (SID) used for the signature of the random number is determined using a decrypting algorithm (INVA) using the encrypted secret key (KID) and a password (MP) supplied by the terminal user. Particular utility for the present invention is found in the area of data processing, although other utilities are also contemplated.
