Certificateless strong designated verifier multi-signature
Tongxin xuebao, 2016 In order to satisfy the application requirements in the fields of judicial administration,e-government,etc.,the definition and security model for certificateless strong designated verifier multi-signature were proposed.Then,the first certificateless ...

Cryptanalysis and design of signature schemes with identity ambiguity in the standard model
Tongxin xuebao, 2011 The security and flaw of the two anonymous signature schemes called ZLW（2008） and LHMM（2009） were analyzed,where the ZLW scheme couldn’t provide signed message verifiability and the LHMM scheme couldn’t resist on the multiple-known-signature existential ...

Post quantum proxy signature scheme based on the multivariate public key cryptographic signature
International Journal of Distributed Sensor Networks, 2020 Proxy signature is a very useful technique which allows the original signer to delegate the signing capability to a proxy signer to perform the signing operation.

A Group Proxy Signature Scheme Based on Key Matrix
工程科学与技术, 2011 :In order to overcome the problems that the existing group proxy signature schemes do not have strong unforgeability and can not resist collusion attack by proxy themselves, a group proxy signature scheme of resisting collusion attack based on key matrix

Strongly Unforgeable Ring Signature Scheme from Lattices in the Standard Model
Journal of Applied Mathematics, 2014 In a ring signature scheme, a user selects an arbitrary ring to be able to sign a message on behalf of the ring without revealing the signer’s identity. Whistle-blowers especially find this useful.

Signatures in the Multi-Unforgeability Setting
IACR Communications in CryptologyQuantum computers may soon be able to compute discrete logarithms, but the high resource cost will likely restrict attackers to only a limited number of such computations. Traditional digital signature schemes —such as \Schnorr

ID-based transitive signature schemes without random oracle
Tongxin xuebao, 2010 Based on waters’ signature scheme,the first identity-based transitive signature scheme was proposed and proved secure against attacks in the standard model.Compared with current transitive signature schemes,the unforgeability of the signature’s ...
