Universal Forgeability of a Forward-Secure Blind Signature Scheme Proposed by Duc et al
نویسندگان
چکیده
Duc et al. proposed a forward-secure blind signature scheme in [1]. They claimed that the scheme is constructed from the provably secure OkamotoGuilou-Quisquater blind signature scheme. But we recently found that their scheme is insecure. In the paper, we show the scheme is universally forgeable by a simple and direct attack.

Double voter perceptible blind signature based electronic voting protocol
Mu et al. have proposed an electronic voting protocol and claimed that it protects anonymity of voters, detects double voting and authenticates eligible voters. It has been shown that it does not protect voter's privacy and prevent double voting. After that, several schemes have been presented to fulfill these properties. However, many of them suffer from the same weaknesses. In this p...

متن کاملUniversally Composable Blind Signatures in the Plain Model
In the universal composability framework, we define an ideal functionality for blind signatures, as an alternative to a functionality recently proposed by Fischlin. Fischlin proves that his functionality cannot be realized in the plain model, but this result does not apply to our functionality. We show that our functionality is realized in the plain model by a blind signature protocol if and on...
متن کاملForward-Secure Blind Signature Scheme Based on the Strong RSA Assumption
Key exposure problem turns out to be very serious in security services. For example, in electronic cash, the problem is very severe since money is directly involved. In other applications of cryptography, it is also a devastating attack. Forward security is the first security notion addressing the this issue. Roughly speaking, forward secrecy is aimed to protect validity of the all usage before...
متن کاملA Forward-Secure Blind Signature Scheme Based on the Strong RSA Assumption
Key exposures bring out very serious problems in security services. Especially, it is more severe in the applications such as electronic cash or electronic payment where money is directly involved. Forward secrecy is one of the security notions addressing the key exposure issues. Roughly speaking, forward secrecy is aimed to protect the validity of all actions using the secret key before the ke...
