Challenge-Response Signatures Sample Clauses

Challenge-Response Signatures. Exponential challenge-response (XCR) signature is introduced by Xxxxxxxx [22] as a building block for key agreement protocol. Such a scheme, an inherently interactive public key signature protocol, requires the verifier to issue a challenge to the signer and the later responses by a signature on a given message. Apart from being unforgeable, challenge-response signature ensures that only the legitimate signer can generate a signature which will make the challenger convinced, i.e. challenge-response signature is challenge-specific. A distinctive feature of Xxxxxxxx’x XCR scheme is that any party who possesses the challenge can always generate the same signature string as the signer. This property of XCR, essentially, makes it the building block for key agreement protocol. As noted by Xxxxxxxx [22], no assumptions regarding third party’s verifiability of a XCR signature is made as the verifiability is (easily) transferable. Our contribution: How concepts in signatures help ID-based key agreement protocols. We propose a strong challenge-response signature scheme in which the verification requires the knowledge of the designated verifier’s private key. To the best of our knowledge, our scheme is the first ID-based challenge-response signature scheme. In the digital signature paradigm, unforgeability against adaptive chosen-message attack is a standard requirement – there exists a signing oracle giving arbitrary signatures of the adversary’s choice. We observe that this concept is somewhat analogous to Session-Key Reveal queries in the key agreement paradigm that returns session keys of the adversary’s choice when asked. Ephemeral parameters are often involved in the computation of signatures, which are also inherent in key agreement protocol. We also note that there are many well-established signature schemes with anonymity concerns. For example, in ring signature, formalized by Xxxxxx, Xxxxxx, and Xxxxxx [27, 28], absolute anonymity is provided whereby a signer can sign a message on behalf of a spontaneous group of possible signers without exposing the identity of the actual signer. It is natural to ask, “Can we borrow concepts from digital signatures to construct key agreement protocols? ” This work provides an affirmative answer. We built on the idea of Xxxxxxxx [22] to propose a “better” ID-based key agreement protocol using com- ponents from our strong pairing challenge-response signature. We also propose an anonymous key agreement protocol using componen...
