摘要： The invention relates to a method for generating a list signature for a message to be signed, said method comprising steps which are carried out by an electronic material support of a member of a list. During said step, the electronic material support only generates an electronic signature according to a sequence number supplied to the electronic material support by a certifying authority, according to evidence of belonging to the list of members, to data relating to the electronic material support, and optionally to a key of an authority qualified to lift the anonymity of the generated signature.
摘要翻译：本发明涉及一种用于生成要签名的消息的列表签名的方法，所述方法包括由列表的成员的电子资料支持来执行的步骤。在所述步骤期间，电子材料支持仅根据由认证机构提供给电子资料支持的序列号，根据成员名单的证据，产生与电子资料支持有关的数据的电子签名，以及可选地具有授权提升生成的签名的匿名性的机构的密钥。

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： 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.
摘要翻译：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。

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.
