Privacy on the Blockchain: Unique Ring Signatures
Ring signatures are cryptographic protocols designed to allow any member of a group to produce a signature on behalf of the group, without revealing the individual signer’s identity. This offers group members a level of anonymity not attainable through generic digital signature schemes. We call this property ‘plausible deniability’, or anonymity with respect to an anonymity set. We concentrate ...
متن کاملCode-based Ring Signature Scheme
McEliece is one of the oldest known public key cryptosystems, however it was not quite as successful as RSA. One main reason is that it is widely believed that code-based cryptosystems like McEliece do not allow practical digital signatures. Although X.M. Wang presented a code-based signature scheme in 1990, some authors find that it is not secure. Recently, T.Courtois et al. show a new way to ...
متن کاملA Strong Proxy Signature Scheme with Proxy Signer Privacy Protection
-Mambo, et al. [3] discussed the delegation of signature power to a proxy signer. Lee, et al. [5] constructed a strong non-designated proxy signature scheme in which the proxy signer had strong nonrepudiation. In this paper, we present an enhancement to their scheme such that the identity of the proxy signer is hidden behind an alias. The identity can be revealed only by the alias authority. We...
متن کاملA New Multivariate-based Ring Signature Scheme
Most of the existing ring signature schemes are based on traditional cryptography, such as RSA and discrete logarithm. Unfortunately these schemes would be broken if quantum computers emerge. The MQ-problem based PublicKey Cryptosystem (MPKC) is an important alternative to traditional PKCs for its potential to resist future attacks of quantum computers. In this paper, we proposed a new ring sig...
متن کاملA Lattice-Based Threshold Ring Signature Scheme
In this article, we propose a new lattice-based threshold ring signature scheme, modifying Aguilar’s code-based solution to use the short integer solution (SIS) problem as security assumption, instead of the syndrome decoding (SD) problem. By applying the CLRS identification scheme, we are also able to have a performance gain as result of the reduction in the soundness error to 1/2 per round. S...
