An Efficient Remote Authentication Scheme for Wireless Body Area Network.

Wireless body area network (WBAN) provide a mechanism of transmitting a persons physiological data to application providers e.g. hospital. Given the limited range of connectivity associated with WBAN, an intermediate portable device e.g. smartphone, placed within WBAN's connectivity, forwards the data to a remote server. This data, if not protected from an unauthorized access and modification may be lead to poor diagnosis. In order to ensure security and privacy between WBAN and a server at the application provider, several authentication schemes have been proposed. Recently, Wang and Zhang proposed an authentication scheme for WBAN using bilinear pairing. However, in their scheme, an application provider could easily impersonate a client. In order to overcome this weakness, we propose an efficient remote authentication scheme for WBAN. In terms of performance, our scheme can not only provide a malicious insider security, but also reduce running time of WBAN (client) by 51 % as compared to Wang and Zhang scheme.

An error‐free data‐hiding scheme for encrypted images

AbstractZhang introduced a novel reversible data‐hiding scheme for encrypted images. At the receiver, the hidden data is extracted by exploiting the spatial correlation in the image. But Zhang's scheme does not perform well for smaller block sizes and incurs bit extraction errors during recovery. We eliminate this problem by omitting those blocks from the data‐hiding operation that causes extraction errors. To identify those blocks at the receiver, we embed their index information into a small portion of the image using a difference expansion method. The experimental results from the proposed scheme indicate that all the hidden data can be successfully retrieved without errors. Copyright © 2017 John Wiley & Sons, Ltd.

A bilinear pairing based anonymous authentication scheme in wireless body area networks for mHealth.

Wireless body area networks (WBANs) have become one of the key components of mobile health (mHealth) which provides 24/7 health monitoring service and greatly improves the quality and efficiency of healthcare. However, users' concern about the security and privacy of their health information has become one of the major obstacles that impede the wide adoption of WBANs. Anonymous and unlinkable authentication is critical to protect the security and privacy of sensitive physiological information in transit from the client to the application provider. We first show that the anonymous authentication scheme of Wang and Zhang based on bilinear pairing is prone to client impersonation attack. Then, we propose an enhanced anonymous authentication scheme to remedy the flaw in Wang and Zhang's scheme. We give the security analysis to demonstrate that the enhanced scheme achieves the desired security features and withstands various known attacks.

Quantum signature-masked authentication schemes

In this paper we analyze the security of Zhang's scheme [Chin. Sci. Bull., 2009, 54: 2018–2021], and find that there are two potential loopholes, i.e. the participants forgery attack and impersonation attack. Then, following the elementary method of Zhang's scheme, we propose a quantum signature-masked authentication scheme, which can be widely used many systems, such as the identity authentication between Digital Set-Top-Box (DSTB) and smart card in secure Digital Video Broadcasting (DVB) service system. In our scheme, a semi-trusted center of authentication CA issues the original credential certificates for a user and the final credential certificates is generated by adding her secret information, that is, the user's final credential certificates is generated by her own and CA together. This new scheme can solve Zhang's scheme security problem. Moreover, analysis results show that our scheme can withstand the forgery attack, impersonation attack and inter-resend attack.

Thwarting intercept-and-resend attack on Zhang’s quantum secret sharing using collective rotation noises

This work deliberately introduces collective-rotation noise into quantum states to prevent an intercept-resend attack on Zhang's quantum secret sharing scheme over a collective-noise quantum channel (Zhang in Phys A 361:233---238, 2006). The noise recovering capability of the scheme remains intact. With this design, the quantum bit efficiency of the protocol is doubled when compared to Sun et al.'s improvement on Zhang's scheme (Sun et al. in Opt Commun 283:181---183, 2010).

Attack and improvement of Zhang’s multi-signature scheme

After analyzing the ID-based digital multi-signature scheme based on RSA ( Rivest-Shamir-Adleman) proposed by Zhang et al. in 2008, a complete attack algorithm was proposed. Firstly, Zhang et al. 's scheme and the attack algorithm were introduced, and then two improved schemes against to the security problem of Zhang's scheme were proposed. The random operation of each signer was changed, and part of computation operation was transferred in both of the improved schemes. The results show that the improved schemes are secure without decreasing the efficiency of signing and verifying. Therefore, the improved schemes are more valuable in practical application.

Threshold proxy signatures

A (t, n) threshold proxy signature scheme allows t or more proxy signers from a designated group of n proxy signers to sign messages on behalf of an original signer. The authors review both Zhang's threshold proxy signature scheme and Kim's threshold proxy signature scheme. They show that Zhang's scheme suffers from some weaknesses and Kim's scheme suffers from a disadvantage. Based on Zhang's scheme, they propose a new threshold proxy signature scheme to defeat the weaknesses of Zhang's scheme and the disadvantage of Kim's scheme.
