Cryptanalysis of Some Group-Oriented Proxy Signature Schemes
[chapter]
2006
Lecture Notes in Computer Science
Preserved Fulltext
As an example, the notion of threshold proxy signature or proxy multi-signature was introduced as a group-oriented variant. ...
In this paper, we show that some threshold proxy signature schemes and proxy multi-signature schemes are all insecure against the malicious original singer(s). ...
Acknowledgement The authors of this paper would like to thank anonymous referees for valuable comments. The ...

Hwang and Chen recently proposed new multi-proxy multi-signature schemes that allow a group of authorized proxy signers to sign messages on behalf of a group of original signers. ...
This paper shows that their schemes are insecure because a malicious proxy signer can forge a signature for a message secretly while participating in the message signing process with the other proxy signers ...
Recently, by combining the notions of multi-proxy signature and proxy multi-signature, Hwang and Chen proposed a new type of group-oriented proxy signature scheme called multi-proxy multi-signature scheme ...
