Direct Anonymous Attestation (DAA) is an anonymous signature scheme designed for anonymous attestation of a Trusted Platform Module (TPM) while preserving the privacy of the devic...
We extend the definitional work of Dwork, Naor and Sahai from deniable authentication to deniable key-exchange protocols. We then use these definitions to prove the deniability fe...
Abstract. Direct anonymous attestation (DAA) is a special digital signature primitive, which provides a balance between signer authentication and privacy. One of the most interesti...
Abstract. In 1998, Blaze, Bleumer, and Strauss proposed a cryptographic primitive called proxy re-encryption, in which a proxy transforms – without seeing the corresponding plain...
We introduce Ad Hoc Anonymous Identification schemes, a new multi-user cryptographic primitive that allows participants from a user population to form ad hoc groups, and then prove...
