Secure distributed signcryption scheme based on vector space
Tongxin xuebao, 2009 A kind of new distributed signcryption protocol was proposed based on the ideal vector space secret sharing scheme and the modified signcryption scheme of Zheng1.Without the involvement of a trusted key distribution center, this protocol could gain its ...

Identity-based Linkable Ring Signcryption on NTRU Lattice [PDF]
Jisuanji kexueAlthough the current lattice-based ring signcryption scheme resists quantum attacks,it has large key storage and high encryption/decryption time.The linkable lattice ring signcryption scheme not only can protect signer anonymity,but also can determine ...

A mutual and anonymous heterogeneous signcryption scheme between PKI and IBC
Dianxin kexue, 2020 Anonymous heterogeneous signcryption scheme can not only transfer data confidentially for users in heterogeneous cryptographic environment,but also provide privacy protection for users of both sending and receiving sides.The security of an anonymous ...

An ID-based Hybrid Broadcast Signcryption Scheme with User Anonymity
工程科学与技术, 2013 :Broadcast signcryption can make the sender send multi messages to recipients by one operation. In order to efficiently solve the problems of low efficiency, large overhead and privacy security in “one-to-many” communication model, an ID-based broadcast ...

Two-way and anonymous heterogeneous signcryption scheme between PKI and IBC
Tongxin xuebao, 2017 Exiting heterogeneous signcryption schemes which were between public key infrastructure (PKI) and identity-based cryptosystem (IBC) have some limitations.A new heterogeneous signcryption scheme between PKI and IBC was proposed.In the random oracle mode ...

Generic Constructions for Verifiable Signcryption [PDF]
, 2012 Signcryption is a primitive which simultaneously performs the functions of both signature and encryption in a way that is more efficient than signing and encrypting separately. We study in this paper constructions of signcryption schemes from basic cryptographic mechanisms; our study concludes that the known constructions require expensive encryption ...

A Security Enhanced Generalized Threshold Signcryption Scheme with Deceit Detection
工程科学与技术, 2010 :By analyzing the first generalized threshold signcryption scheme (WCL scheme) and its improved schemes (TJC scheme, etc.), it was found that they can’t resist several attacks such as equation attack and can’t realize threshold designcryption.

Revocable ID-based Signcryption Scheme
工程科学与技术, 2014 :In order to revoke private key leaks or malicious users in a signcryption system,a new revocable identity-based signcryption scheme was proposed.In this scheme,the master key was randomly divided into two parts,which were used to construct the initial ...

Ring signcryption scheme based on domestic cryptographic algorithm SM9
Tongxin xuebaoTo address the linear computational increase with ring size in existing identity-based ring signcryption schemes, an efficient ring signcryption scheme based on the Chinese national cryptographic standard SM9 was proposed.
