After that both mobile station and base station compute a shared session key using Diffie-Hellman key exchange scheme Beller and Yacobi's protocol Beller and Yacobi designed a protocol that uses ElGamal algorithm (from now on we call it BY) and afterwards Boyd and Mathuria showed that this protocol is vulnerable to a man-in-the-middle attack and improved it [4]
A Structured Multisignature Scheme from the Gap Diffie-Hellman Group Chih-Yin Lin and Tzong-Chen Wu and Fangguo Zhang Abstract: In this paper the authors propose a new structured multisignature scheme that considers the signing order among co-signers

We provide two versions of our scheme: the first one is based on the conventional NTRU encryption scheme and although it lacks a security proof remains as efficient as its predecessor the second one is based on a variant of NTRU proposed by Stehl and Steinfeld which is proven CPA-secure under the hardness of the Ring-LWE problem To the best of our knowledge our proposals are the first

Moreover the size and the verification of a structured multisignature is the same as those of an individual signature generated by any co-signer Arithmetically the proposed scheme makes use of the Gap Diffie-Hellman (GDH) signature scheme recently presented by Boneh Shacham and Lynn

In contrast to the only prior scheme to provide this functionality ours offers improved security that does not rely on synchronized clocks or a trusted first signer We provide formal security definitions and support the proposed schemes with security proofs under appropriate computational assumptions

CAi has a private key xi and a corresponding public key yi in the multisignature scheme where xi is randomly selected from GF(P) and where y i = G xi mod P The collective public key of the two CAs is y =y1y2 mod P To generate a certificate for the user's public key CAi computes ri = G ki mod P and sends it to the other CA where ki is a random element from GF(P) and kept secret Each CAi
This signature scheme works in any group where the Decision Di e-Hellman problem (DDH) is easy but the Computational Di e-Hellman problem (CDH) is hard We refer to such groups as gap groups [6 26] Recently there have been a number of constructions using such gap groups [6 19 8 4] Surprisingly general gap groups are insu cient for

An aggregate signature scheme allows anyone to compress multiple individual signatures from various users into a single compact signature The main objective of such a scheme is to reduce the costs on storage communication and computation However among existing aggregate signature schemes in the identity-based setting some of them fail to achieve constant-length aggregate signature or
the structure retains information of faces and vertices in an exactly identical form A single record of data which has this type of symmetry with respect to faces and vertices can be called a self-dual element Although the WE is a self-dual data structure the WE data structure was
