    Abstract: The method for authentication and electronic signature is of the private-key, challenge and response type between a user requesting an authorisation (for a specific transaction, or for access to particular resources), via, for example, a smart card (1) and a controller -check terminal (2)-supplying the authorisation. To increase security of the authorisation or authentication operations, the smart card (1) comprises a chaotic generator (23) generating user's acknowledgement code, which is compared with a comparison code generated by the check terminal (2) using a chaotic generator (30) which is the same.

    Abstract: In order to protect the contents of an electronic document through an encryption system based on an initial confusing step in a scrambler and a subsequent diffusion step in a chaotic processor, both steps being of a chaotic type, initially (51) encryption keys (c j ) and an initial chaotic value (X 0 ) are acquired; input character strings (IN) are acquired (53); diffused character strings (s(t)) are calculated (54) using the input character strings, the encryption keys (C j ), and previous diffused character strings (s(t-j)). After a certain number of iterations, sets of diffused character strings (S j ) are added (63) to subsequent chaotic values (X) generated by a chaotic processor (61) to obtain encrypted words (X CR ). Decryption is obtained through two successive operations, wherein the encrypted words are added to chaotic values identical to the encryption values (X) and subtracted from previously decrypted words using an unscrambler element having a structure similar to that of the scrambler and using identical encryption keys.

Each cell represents a hardware implementation of a model of fuzzy inference rules. The model is constructed as a fuzzy circuit architecture which is implemented, preferably, in the form of an integrated circuit with VLSI CMOS technology which generates and controls the reaction diffusion mechanism typical of auto-waves by means of a fuzzy neural network.
