Abstract:
A method and an element of ciphering by an integrated processor of data to be stored in a memory, including applying a ciphering algorithm which is a function of a key specific to the integrated circuit and of an initialization vector, and of memorizing at least the ciphered data, the initialization vector depending at least on the address of storage of the data in the memory.
