    摘要： A processor for executing a Rijndeal algorithm which applies a plurality of encryption rounds to a data block array in order to obtain an array of identical size, each round involving a key block array and a data block substitution table, wherein said processor comprises: a first input register (102) containing an input data block column; an output register (111) containing an output data block column or an intermediate block column; a second input register (101) containing a key block column or the intermediate data blocks; a block substitution element (104) receiving the data one block at a time following the selection (103) thereof in the first register and providing, for each block, a column of blocks; an element (109) applying a cyclic permutation to the substitution circuit column blocks; and an Exclusive-OR combination element (110) combining the permutation circuit column blocks with the content of the second register, the result of said combination being loaded into the output register.

    摘要： A method of establishing an encrypted communication by means of keys between a first electronic device associated with a first trusted authority and a second electronic device, including generating a first secret key associated with the first device for the management of the communication, generating, at least in part by means of the first authority, a second secret key associated with the second device for the management of the communication. The method includes generating the first key at least in part by a second trusted authority associated with the second device that is distinct and autonomous from the first authority. Alternatively, the generation of the first key is performed, at least in part, by the second device passing through the second trusted authority.

    摘要： A method establishes a communication between a first electronic device associated with a first trusted authority and a second electronic device. The method includes: making a first key available to the first device for the communication between the first authority and the first device. A second trusted authority, associated with the second device and distinct and autonomous with respect to the first authority, generates a second key in order to communicate with the second device. Furthermore, the method includes: making the second key available to the second device; and providing the first and second devices with a communication key, to be used communication between the first and second devices, through at least one of the first and second authorities.

    摘要： A method of establishing an encrypted communication by using keys between a first electronic device associated with a first trusted authority and a second electronic device, including generating a first secret key associated with the first device for the management of the communication, generating, at least in part by the first authority, a second secret key associated with the second device for the management of the communication. The method includes generating the first key at least in part by a second trusted authority associated with the second device that is distinct and autonomous from the first authority. Alternatively, the generation of the first key is performed, at least in part, by the second device passing through the second trusted authority.
