摘要： A method and apparatus for proving and a method and apparatus for verifying that a secret value is a member of a predetermined set of values. The proving mechanism receives a set of signatures which has respective values in the predetermined set signed using a private key. The proving mechanism sends to the verifying mechanism a commitment on the secret value of the proving mechanism. The proving mechanism and verifying mechanism then communicate to implement a proof of knowledge protocol demonstrating knowledge by the proving mechanism of a signature on the secret value committed to in the commitment, thus proving that the secret value is a member of the predetermined set.

摘要： A cryptographic method is provided for a host system having an associated trusted platform module. A first contribution to a message is computed by the TPM based on a first secret parameter stored in the TPM. The host system computes a second contribution to the message based on a second secret parameter stored in the host system outside the TPM. The first and second contributions to the message are then combined by either the host or the TPM and a first proof is conducted, proving to the host system that the contribution of the TPM was computed correctly or proving to the TPM that the contribution of the host was computed correctly.

摘要： Method and apparatus for generating cryptographic credentials certifying user attributes and making cryptographic proofs about attributes encoded in such credentials. Attributes are encoded as prime numbers E in accordance with a predetermined mapping and a cryptographic credential is generated encoding E. To prove that an attribute encoded in a cryptographic credential associated with a proving module of the system is a member of a predetermined set of user attributes, without revealing the attribute in question, the proving module determines the product Q of respective prime numbers corresponding to the attributes in the set in accordance with the predetermined mapping of attributes to prime numbers. The proving module demonstrates to the receiving module possession of a cryptographic credential encoding a secret value that is the prime number E, and then whether this secret value divides the product value Q.

摘要： A protocol for anonymous access to a database where the different records have different access control permissions is described. The permissions can be attributes, roles or rights that an authorized user needs to have to access the record. The database provider does not learn which record the user accesses and which attributes or roles the user has when she accesses the database. The database provider publishes the encrypted database where each record is encrypted with a key that is derived from at least the index of the record, its access control attributes and a secret key of the database provider. The user obtains a credential from an issuer for each access control attribute (ACL) that is associated with the user. Then the user retrieves the key for a particular record from the database provider and uses this key to decrypt the encrypted record.
