Provable security signcryption scheme based on RLWE without trapdoor [PDF]
Tongxin xuebao, 2020 In view of the existing efficiency and security problems of lattice based signcryption,with the ABB16’s signature scheme ring-TESLA,a signcryption scheme without trapdoor named RLWE-SC was constructed,which achieved indistinguish ability against adaptive

An efficient signcryption scheme with key privacy and its extension to ring signcryption
Journal of Computer Security, 2010 In Information Processing Letters (2006), Tan pointed out that the anonymous signcryption scheme proposed by Yang, Wong and Deng (YWD) in ISC 2005 provides neither confidentiality nor anonymity. However, no discussion has been made on how a secure scheme can be made and there is no secure scheme available to date.

On the Security of Two Ring Signcryption Schemes. [PDF]
IACR Cryptol. ePrint Arch., 2009 Ring signcryption is a cryptographic primitive, that allows an user to send a message in confidential, authentic and anonymous way, i.e. the recipient of the message is convinced that the message is valid and it comes from one of the ring member, but ...

Identity based ring signcryption schemes revisited
Identity based ring signcryption schemes revisitedRing Signcryption is used to provide a graceful way to leak trustworthy secrets in an anonymous, authenticated and confidential way. To the best of our knowledge, seven identity based ring signcryption schemes were reported in the literature. In this paper, we show that five of them are insecure in one or the other way. We then propose a new scheme and

A Publicly Verifiable Leveled Fully Homomorphic Signcryption Scheme
IET Information Security, Volume 2023, Issue 1, 2023., 2023 With the deepening of research, how to construct a fully homomorphic signcryption scheme based on standard assumptions is a problem that we need to solve. For this question, recently, Jin et al. proposed a leveled fully homomorphic signcryption scheme from standard lattices.
