Abstract: The invention relates to a method for securing the execution of an onboard NFC application in a secure element which does not include a native OTA application. The secure element interacts with a mobile terminal including a removable card. According to the invention, the method includes recording an identifier of the removable card in the secure element no later than when the NFC application is loaded onto the secure element. When an event occurs, a verification is made, in the secure element, whether or not the identifier of the removable card present in the mobile terminal corresponds to the identifier previously stored in the secure element, in order to detect a possible change of the removable card.

Abstract: A cryptographic method carries out a modular exponentiation of the type C=A<B1> mod N, where A is an operand, B1 is a first exponent, N is a modulus and C is a result. The method includes the steps of masking the operand A by a number s, carrying out a modular exponentiation of the masked operand by the exponent B1, and demasking the result of the exponentiation, by removing a contribution from the random number s from the result of the exponentiation. During the step of masking the operand A, the operand A is multiplied by a parameter of the form K<s.B2>, where K is a constant and B2 is a second exponent such that B1.B2=1 mod N. The method is implemented preferably by using a Montgomery multiplier. The preferred choice for the constant K is K=2p, p being an integer lying between 0 and n, n being an upper bound of the size of the modulus N and conventionally depending on the choice of implementation of the Montgomery multiplication.

Abstract: A device, such as a chip card, is connected to a host platform that is linked to a packet network such as the Internet. The device detects security policy designation parameters in packets leaving and entering the platform and processes the packets according to stored security policies designated by the designation parameters detected. The security information linked to a user can therefore be moved from one platform to another and it is not processed by the platform. Security policies are managed by a server with which the device can initiate a communication when no security policy corresponding to the policy designation parameters detected in a packet is recognized, so that the server can assist the device in negotiating a security policy.

Abstract: (EN) The invention makes it possible to allow several applications to coexist in the same card; the implementation of the applications uses reading and writing of data by the reader in the same memory location. The invention is a method for exchanging data between a mobile authentication device 3 supporting several applications Z1 to Z3 and a reader dedicated to one application in which the reader sends an authentication command and at least one read and/or write command. The authentication command allows the mobile device to authorise a transaction for at least part of an application Z1 to Z3 supported by the said mobile device. In response to the authentication command, the mobile device selects the application of the device that corresponds to the reader. The read and/or write command is carried out by addressing a definite block of data. In response to the read and/or write command, the mobile device addresses the block of the selected application.

Abstract: A method for encrypting/decrypting a message includes the initial step of generating keys by the sub-steps of generating a public key; generating a decryption key; and generating a derivation key. For a first entity, the message is encrypted using the public key and a cipher. For a second entity, the cipher is decrypted to find the message. A trapdoor associated with said message is generated. The trapdoor corresponds to a derivative of the derivation key specific to the message. A test cipher is tested, using the trapdoor associated with the message, to determine if the test cipher is an encryption of the message using the public key.
