A BATCH VERIFICATION FOR MULTIPLE PROXY SIGNATURE

SHIANG-FENG TZENG, CHENG-CHI LEE, MIN-SHIANG HWANG
2011 Parallel Processing Letters  
In this article, we proposed a batch verification scheme for multiple proxy signatures to reduce the proxy signature verification time. The proposed scheme is not only efficient because it does not verify each individual proxy signature separately, but also secure because it can detect forged multiple proxy signatures without failure.

Generalization of proxy signature based on elliptic curves

Min-Shiang Hwang, Shiang-Feng Tzeng, Chwei-Shyong Tsai
2004 Computer Standards & Interfaces  
In the past, proxy signature schemes were usually proposed to deal with one or two separate proxy conditions each. To make a difference, in this paper, the authors shall present a generalized version of proxy signature scheme. Compared to earlier proxy signature schemes, our novel scheme can be applied to every possible proxy situation. The proposed scheme allows the original group of original signers to delegate their signing capability to a designated proxy group. The proxy group of proxy
more » ... group of proxy signers can cooperatively generate a proxy signature on behalf of the original group. Any verifier can verify the proxy signature on the message with the knowledge of the identities of the actual original signers and the actual proxy signers. With this article, we also aim to demonstrate how to specify proxy signature schemes on elliptic curve over finite fields. In addition, some possible attacks have also been considered, and our security analysis will show that none of them can successfully break the proposed scheme.

Improvement of signature scheme based on factoring and discrete logarithms

Li-Hua Li, Shiang-Feng Tzeng, Min-Shiang Hwang
2005 Applied Mathematics and Computation  
Laih and Kuo proposed two efficient signature schemes based on discrete logarithms and factorization. However, their schemes require many keys for a signing document. In this article, we shall propose an improvement of Laih and KuoÕs signature schemes. The improved scheme will outperform their schemes in the number of keys.

Multilevel secure database encryption with subkeys

Min-Shiang Hwang, Wei-Pang Yang
1997 Data & Knowledge Engineering  
In this paper, we propose a multilevel database encryption system with subkeys. This new system is called the record-oriented cryptosystem which encrypts each record with different field-subkeys according to a security class of the data element. Each field is decrypted individually by the field-subkeys of which security class is higher than or equal to that of the encrypted field-subkeys. This system is based on the Chinese Remainder Theorem. Our scheme can protect the finest level of
