Authors: Zhang Jian Hong , Wang Wei , Zhen Wei Na , Dong Qiao Cui
Published: December 2014

As an important crypto graphical tool, ring signature is able to realize full anonymity and identity protection. Comparison the traditional PKI, Identity-based (ID-based) cryptography is a very good cryptosystem since it eliminates the need for checking the validity of the certificates of traditional public key system. In this work, we propose an efficient ring signature scheme by combining ID-based cryptography and Schnorr signature conception. Our scheme has some advantages for efficiency. In our proposed scheme, no pairing operators are needed in the whole signing phase and the verifying phase. It reduces the signer’s computation cost and increases the whole signature algorithm’s efficiency. In terms of signature’s length, our scheme only needs (n+1)|G| bits. Our ring signature can achieve full anonymity and unforgeability. The security of the scheme is related to two classical security assumptions: computational diffie-hellman problem and discrete logarithm problem.

An Improved RSA-Based Certificateless Signature Scheme
Authors: Dong Xue Dong , Lu Hui Min
Published: December 2014

Certificateless-based signature can eliminate the need of certificates in the Public Key Infrastructure and solve the inherent key escrow problem in the identity-based cryptography. In 2012 Zhang et al. [J. Zhang and J. Mao, An efficient RSA-based certificateless signature scheme, Journal of Systems and Software, vol. 85, pp. 638-642, 2012] proposed the first certificateless signature scheme based on RSA operations and showed that their scheme is provably secure in the random oracle model. However, He et al. [D. He, M.Khan, and S. Wu, On the security of a RSA-based certificateless signature scheme, International Journal of Network Security, vol.16, no.1, pp.78-80, 2014] recently showed that Zhang et al.'s scheme is insecure against a type I adversary who can replace users' public keys. In this paper, we propose an improved version based on RSA which not only keeps the original security properties of the signature, but also is secure against a type I adversary.

Authors: Meng Fan Zhi , Liu Yuan , Zhang Chun Rui , Li Tong , Yue Yang
Published: December 2014

One of the major challenges in constructing wireless sensor networks (WSNs) is to ensure the quality of coverage (QoC) as well as save energy. Considering the cooperative sensing model and the random deployment policy, the judgment model of redundant node without location information is presented. Furthermore, the distributed collaborative scheduling algorithm (DCSA) is designed to guarantee the QoC of networks with the least number of nodes. It chooses the uniformly-located working nodes and makes sure that the energy consumption of each node consumes homogeneously. Simulation results show that the DCSA policy not only provides the desired QoC of networks, but also reduces the number of working nodes significantly, saves the energy of the networks, and extends the network lifetime.
