Abstract: The integrated processor coding chops digital word streams into predetermined sizes and generates key codes (Cb) generated pseudo randomly (10). The codes operate from a key function (K) and vector initialisation (IV) which changes for each block. The digital word blocks and key codes are combined continuously and memorised in a memory (23).

Abstract: The method involves applying a ciphering algorithm with a function of a key specific to an integrated circuit of an initialization vector. A ciphered data is memorized, where the initialization vector includes a storage address of the data in a memory and a differentiation value. An algorithm identical to the ciphering algorithm is applied based on the address of the ciphered data. An independent claim is also included for a smart card comprising an electronic assembly.

Abstract: The method involves selecting a secret key from keys stored with key identifiers in registers. Data is divided into a stream of data words of determined size. A pseudo-random number is generated based on the secret key and an initialization vector. The data word and number are combined to generate an encrypted data word and the encrypted data word is stored with the vector and the identifier of the key in an external memory (23). Independent claims are also included for the following: (A) a device for implementing a data encrypting method (B) an electronic apparatus having processors with encrypting/decrypting unit.

Abstract: The circuit has an input shift register (41) to receive bits flow and a comparator (42) to compare content of the register with predetermined patterns stored in a table (43). A load detector (44) detects overflow of counters with respect to a determined threshold. The detector provides the result to condition the state of a word or randomness validation bit of bit stream provided by random number generator.
