On the Security of Huang-Chang Multi-signature Schemes
Recently, based on RSA and discrete logarithm with composite modulus, Huang and Chang proposed two multisignature schemes with distinguished signing authority and claimed that the...

Secure acknowledgment aggregation and multisignatures with limited robustness
In certain reliable group-oriented and multicast applications, a source needs to securely verify whether all (and if not all, which) intended receivers have received a message. How...

Original Signer's Forgery Attacks on Discrete Logarithm Based Proxy Signature Schemes
A proxy signature scheme enables a proxy signer to sign messages on behalf of the original signer. In this paper, we demonstrate that a number of discrete logarithm based proxy si...

On the Fly Authentication and Signature Schemes Based on Groups of Unknown Order
Abstract. In response to the current need for fast, secure and cheap public-key cryptography, we propose an interactive zero-knowledge identification scheme and a derived signature...
