Anonymous RFID authentication supporting constant-cost key-lookup against active adversaries
: In the absence of sufficiently optimised public key constructions, anonymous authentication for Radio-Frequency Identification Devices (RFIDs) requires state synchronisation betw...

An optimistic fair exchange protocol and its security in the universal composability framework
: Fair exchange protocols allow both or neither of two parties to obtain the other's items, and this property is essential in e-commerce. In this paper, we construct an optimi...

On the relation among various security models for certificateless cryptography
: Certificateless cryptography is a promising technology for solving the key escrow problem in identity-based cryptography. However, the lack of a unified set of definitions and se...

Practical key-recovery attack against APOP, an MD5-based challenge-response authentication
Abstract: Hash functions are used in many cryptographic constructions under various assumptions, and the practical impact of collision attacks is often unclear. In this paper, we s...

An efficient one-move Nominative Signature scheme
Abstract. A signer in a Nominative Signature (NS) scheme can arbitrarily choose a nominee, then jointly generate a signature in such a way that the signature can only be verified w...

Securing group key exchange against strong corruptions and key registration attacks
: In Group Key Exchange (GKE) protocols, users usually extract the group key using some auxiliary (ephemeral) secret information generated during the execution. Strong corruptions ...

Efficient lattice-based signature scheme
: In Crypto 1997, Goldreich, Goldwasser and Halevi (GGH) proposed a lattice analogue of McEliece public key cryptosystem, in which security is related to the hardness of approximat...
