Formal proofs of cryptographic security of Diffie-Hellman-based protocols
, 2007 . We present axioms and inference rules for reasoning about Diffie-Hellman-based key exchange protocols and use these rules to prove authentication and secrecy properties of two important protocol standards, the Diffie-Hellman variant of Kerberos, and ...

, 2012 [[abstract]]In 2008, based on the two-party Diffie-Hellman technique, Biswas proposed a contributory group key exchange protocol called the Group-DH protocol. This contributory property is an important one of group key agreement.

A TPM Diffie-Hellman Oracle [PDF]
, 2013 This note describes a Diffie-Hellman oracle, constructed using standard Trusted Platform Module (TPM) signature APIs. The oracle allows one to compute the exponentiation of an arbitrary group element to a specified TPM-protected private key.

An Observation about Variations of the Diffie-Hellman Assumption [PDF]
, 2009 We generalize the Strong Boneh-Boyen (SBB) signature scheme to sign vectors; we call this scheme GSBB. We show that if a particular (but most natural) average case reduction from SBB to GSBB exists, then the Strong Diffie-Hellman (SDH) and the ...

An ID-based Hybrid Broadcast Signcryption Scheme with User Anonymity
工程科学与技术, 2013 :Broadcast signcryption can make the sender send multi messages to recipients by one operation. In order to efficiently solve the problems of low efficiency, large overhead and privacy security in “one-to-many” communication model, an ID-based broadcast ...

The Diffie-Hellman problem and generalization of Verheul\u27s theorem
, 2008 Bilinear pairings on elliptic curves have been of much interest in cryptography recently. Most of the protocols involving pairings rely on the hardness of the bilinear Diffie-Hellman problem.

Practical group signature scheme with verifier-local revocation
Tongxin xuebao, 2011 An efficient approach of member revocation in group signature is verifier-local revocation.In this approach,revocation messages are only sent to signature verifiers,while signers have no involvement.There are some problems in group signature with ...
