    摘要: A method and apparatus are provided to perform a cryptographic task on at least one numerical datum in an electronic hardware component. The method includes a step of at least partial use of an encryption function. This encryption function includes a basic encryption function obtained by the addition between an intermediate function arising from composition of a coding function with a first function, and a second function. This method can be applied to the encryption of a datum or to the decryption of a datum. Also, a method is provided for generating a public key and a device able to implement one of these methods.

    摘要: A method is provided for generating a correspondence table suitable for use in a cryptographic processing method and comprising storing a plurality of input data and of output data in the table, each input datum being associated with at least one output datum in the table. For each input datum, at least one of the output data is obtained by applying a coding function to a first subsidiary datum and to an encrypted intermediate datum depending on the input datum. Also provided are a corresponding encryption method, a storage unit suitable for storing the correspondence table generated by the above generation method, a device for physically implementing such a correspondence table, a decryption device including such a storage unit, and a computer program product suitable for implementing the above generation method.

    摘要: In a method of establishing a secure communication link between a first terminal and a second terminal, the first terminal is connected to a third terminal which can be connected to a mobile telephone network and the second terminal is connected to an authentication element of the telephone network. The method includes: transfer of an authentication datum from the third terminal to the network authentication element; following authentication of the third terminal, the transfer of a random variable from the network authentication element to the third terminal; the parallel generation of a session key by the third terminal and the network authentication element from the random variable; the generation by the first and second terminals of a shared key from the session key; and the opening of a secure communication link with the use of the shared key.

    摘要: The invention relates to a public key cryptographic method and system, a certification server and memories adapted for said system. In said public key cryptographic system, there is insufficient information contained in an electronic public key certificate alone to retrieve the public key. The inventive system comprises at least a second memory (52, 72) in which complementary information is stored, which can be used to retrieve the public key when used together with the information contained in the certificate. According to the invention, access to said complementary information is reserved to a limited number of authorised terminals among the group of terminals that can verify the certificate signature.
