摘要： The invention relates to a method for unique authentication of a user (U) by at least one service provider (SP), said method including a preliminary identity federation stage of federating an identity (user@sp) of said user for said service provider and an identity (user@idp) of the user (U) for an identity provider (IdP). According to the invention, said preliminary identity federation stage includes the steps of: the user (U) generating a user alias ([alias]) for that service provider (SP) and sending said identity provider (IdP) a masked alias ([alias]masked) deduced from said alias, the identity provider (IdP) associating said masked alias ([alias]masked) for that service provider (SP) with the identity (user@idp) of the user for the identity provider (IdP) and sending the user (U) elements for calculation by the user of a signature (σ) of a message (msg) containing the non-masked alias ([alias]), the user (U) calculating said signature (σ) and sending the service provider (SP) said message (msg) with said signature (σ), and the service provider (SP) verifying said signature (σ), authenticating the user (U), and associating said alias ([alias]) with the user's identity (user@sp) for the service provider (SP).

摘要： 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.
摘要翻译：一种匿名安全的在线支付系统和方法，基于部分盲签名密码方法，具有可撤销的匿名性。为此，匿名服务器（SA）使得客户（C）能够基于不使匿名服务器将付款方式链接到客户（C）的协议来获取在线匿名支付手段。支付服务器（SdP）包括使用匿名支付装置（50）打开匿名帐户的装置。客户（C）可以从商户网站（SM）进行在线购买，而无需给予银行卡号码，并且对于商户而言更为普遍地存在于交易中存在的任何实体或不在其中的实体。然而，在客户发生欺诈的情况下，这个匿名可能被信任的实体撤销。最后，客户可以在搬家时付款。

摘要： 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.

摘要： 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.
摘要翻译：本发明涉及使得组（G）的成员（M）能够通过定制数据（z; K）产生伴随着签名（8）的消息（m）的系统，该签名（8）向验证者证明该消息来自该组（G）的成员。本发明的特征在于，定制数据是电子物理介质（26）的形式。有利地，后者还包括：用于在消息（m）的签名S之前从定制数据产生定制密码（C）的加密装置（B3），用于产生消息m的组合的装置（B5）签名和与所述消息相关联的密码（C），例如以消息（m）与密码（C）的级联的形式，以及用于与消息（m）签名（Sig）消息（M）的装置以与所述消息相关联的密码（C）的形式的定制数据（z; K）。有利地，物理介质是智能卡（26）等。

摘要： In a fair blind signature process, a user interacts with a signer in order to complete a 7-tuple (A,e,s,t,xu,x,m) such that Ae=a0a1xa2ma3xua4ta5s (mod n), where a0, a1, a2, a3, a4 and a5 and n are elements of the Signer's public key (PUBKs). During the signature-issuing phase the user (U) provides the signer (S) with a data element (a1x) encrypted according to a key (f) known to a trusted authority (TA), and this data element (a1x) is disclosed during transmission of the signed message. Similarly, the signed message is transmitted associated with second encrypted data comprising a second data element (a3xu) encrypted according to a key (f) known to the trusted authority (TA), and this second data element (a3xu) is disclosed to the Signer during the signature-issuing phase. Thus, the trusted authority (TA) can revoke the anonymity of the digital signature.
摘要翻译：在公平盲签名过程中，用户与签名者进行交互以完成7元组（A，e，s，t，xu，x，m），使得Ae = a0a1xa2ma3x a4ta5s （mod n），其中a0，a1，a2，a3，a4和a5和n是签名者公钥（PUBK）的元素。在签名发布阶段，用户（U）向签名者（S）提供根据可信管理机构（TA）已知的密钥（f）加密的数据元素（a1x），并且该数据元素（a1x）被公开在传输签名的消息。类似地，与第二加密数据相关联地发送签名的消息，该第二加密数据包括根据可信管理机构（TA）已知的密钥（f）加密的第二数据元素（a3x />），并且该第二数据元素（a3x＆lt; / sub2））在签名发布阶段向签署者公开。因此，可信管理机构（TA）可以撤销数字签名的匿名性。

摘要： A cryptographic method and a chip card which is used to carry out the method. Before any calculation is performed by a computing means of the chip card, the chip card reads (2) an integral list, in a storage means of a second entity, of identifiers of first proprietary entities of a chip card. Such list is linked to each status assigned to each of the first entities by the second entity. Subsequently, the chip card compares (3) the identifier stored in a storage means of the chip card with the contents of the list, in order to authorize (5) or prohibit (4) any calculation by the computing means depending on the result of the comparison.
摘要翻译：用于执行该方法的加密方法和芯片卡。在通过芯片卡的计算装置执行任何计算之前，芯片卡在（2）芯片卡的第一专有实体的标识符的第二实体的存储装置中读取（2）整体列表。该列表与由第二实体分配给每个第一实体的每个状态相关联。随后，芯片卡将存储在芯片卡的存储装置中的标识符与列表的内容进行比较（3），以便授权（5）或禁止（4）根据计算装置的任何计算比较。
