Abstract: The transaction is made between an object and a terminal. According to the invention, an authentication value is inserted in the object which is a digital signature appearing on an identifier of the object. Each object also has a diversified key created from a base key diversified by the identifier. The terminal can thus authenticate the identifier and check that the debit has actually been made.Application to electronic payment.

Abstract: The invention concerns a list signature method comprising: an organization phase whereby reliable authority defines parameters for implementing an anonymous electronic signature; a phase which consists in registering persons on a list of authorized members to generate a list signature, during which each person calculates a private key, and the reliable authority delivers to each person a certificate for membership of the list; a phase which consists in defining a serial number; a phase wherein a member of the list generates by means of certificate a signature containing an element common to all the signatures issued by one single member with one single serial number; a phase which consists in verifying whether the signature has been generated by a member of the list and whether the serial number has been used to generate the signature.

Abstract: An anonymous and secure on-line payment system and method based on the partially blind signature cryptographic method with revocable anonymity. To this end, an Anonymity Server (SA) enables the Customer (C) to acquire on-line anonymous payment means on the basis of a protocol that does not enable the Anonymity Server to link the payment means to the Customer (C). The Payment Server (SdP) comprises means for opening an anonymous account using the anonymous payment means (50). A Customer (C) can make an on-line purchase from a Merchant Site (SM) without having to give a bank card number and remaining anonymous to the merchant and more generally to any entity present in the transaction or absent therefrom. However, this anonymity may be revoked by a trusted entity in the event of fraud on the Customer. Finally, a Customer can make payments when on the move.

Abstract: A cryptographic method and apparatus for anonymously signing a message. Added to the anonymous signature is another signature which is calculated (operation 13) using a private key common to all the members of a group authorized to sign and unknown to all revoked members. The private key is updated (operations 8, 11) at group level on each revocation within the group and at member level only on anonymous signing of a message by the member.

Abstract translation: 用于匿名签名消息的密码方法和装置。 添加到匿名签名是另一个计算的签名（操作13），使用对所有被撤销的成员授权签名和未知的组的所有成员共同的私钥。 在组内每个撤销的组级别和成员级别的私有密钥被更新（操作8,11），只有成员匿名签名消息。

Abstract: The invention concerns a system enabling a member (M) of a group (G) to produce, by means of customized data (z; K), a message (m) accompanied by a signature (8) proving to a verifier that the message originates from a member of the group (G). The invention is characterized in that the customized data is in the form of an electronic physical medium (26). Advantageously, the latter also incorporates: encrypting means (B3) for producing a customized cipher (C) from the customized data prior to the signature S of the message (m), means (B5) for producing a combination of a message m to be signed and the cipher (C) associated with said message, for example in the form of a concatenation of the message (m) with the cipher (C), and means (B6) for signing (Sig) the message (m) with the customized data (z; K) in the form of a cipher (C) associated with said message. Advantageously, the physical medium is a smart card (26) or the like.

Abstract: In an electronic voting process, a voter (Vi) encrypts his vote (vi) according to the encryption scheme (ETM) of a tallier mix-net (50) used to tally up the votes cast. The voter (Vi) obtains on his encrypted vote, (xi), from an admin server module (20), a digital signature according to a fair blind signature scheme (FBSS). The encrypted vote (xi) is encrypted a second time, together with the unblinded digital signature (yi) thereof by the admin server, using the encryption scheme (EM) of a randomizing mix-net (40), to yield an output (ci), and the voter uses his own signature scheme (Si) to sign this, giving (σi). The voter sends an ID code and data including (ci,σi) to a bulletin board server (30). Discrepancies in this vote data can be detected and their origin traced by prompting the randomizing mix-net servers (40) to provide proofs of correctness, and using the signature-tracing mechanism of FBSS.
