摘要： A method and device for encrypting and/or decrypting binary data blocks protecting both confidentiality and integrity of data sent to or received from a memory. The encryption method comprises steps of: applying to the input data block a reversible scrambling process, the scrambling process providing a scrambled data block in which the bits of the input data block are mixed so that a modification of one bit in the scrambled data block impacts on every bit of the input data block, and applying to the scrambled data block a stream cipher encryption algorithm providing an encrypted data block. Application can be made to secured integrated circuits requiring to securely store data in an external memory.

摘要： The invention concerns a method and a system for customizing electronic components (2), by substituting in a nonvolatile storage each one first secret key (Ks) with a second secret key (Ks′), using a secure authentication module (1) automatically generating said second key after reconstructing the first key from an identifier of the component during customization, which consists in conditioning, on the authentication module side, the supply of the second key for a current component upon reception of a confirmation message for key substitution of at least one previous component.

摘要： An offline payment method includes communicating a commitment value calculated by an electronic check medium to a terminal configured to receive a payment from the electronic check medium. The commitment value is calculated based on a first authentication code and a secret key, wherein the first authentication code is calculated based on a payment amount and a secret verification key. The terminal determines and communicates a random/pseudo-random guesstimation to the electronic check medium in response to receiving the verification code, the random/pseudo-random guesstimation being configured to verify that the electronic check medium is authentic. The electronic check medium determines and communicates a second authentication code to the terminal, the second authentication based upon the random/pseudo-random guesstimation. The terminal compares the second authentication with the random/pseudo-random guesstimation to verify the second authentication and accepts payment from the electronic check medium when the second authentication is verified.
