Provable secure identity based generalized signcryption scheme [PDF]

Theoretical Computer Science, 2010
According to actual needs, a generalized signcryption scheme can flexibly work as an encryption scheme, a signature scheme or a signcryption scheme. In this paper, firstly, we give a security model for identity based generalized signcryption which is ...

Lattice‐based signcryption

Concurrency and Computation: Practice and Experience, 2012
SUMMARYSigncryption is a cryptographic primitive that performs simultaneously both the functions of digital signature and public‐key encryption, at a cost significantly lower than that required by the traditional signature‐ then‐encryption approach.

Efficient Constructions of Signcryption Schemes and Signcryption Composability

2009
In this paper, we investigate simple but efficient constructions of signcryption schemes. Firstly, we show how symmetric primitives can be used to efficiently achieve outsider multi-user security, leading to a signcryption scheme with the currently lowest ciphertext and computational overhead.

Efficient Distributed Signcryption Scheme as Group Signcryption

2003
The existing distributed signcryption is designed for distributing a signcrypted message to a designated group. However, it does not provide confidentiality of sender ID and its extension to a group signcryption has certain weakness. This study solves the weakness and extends to an efficient group signcryption.

On security of a certificateless signcryption scheme

Information Sciences, 2013
It would be interesting if a signcryption scheme in the standard model could be made certificateless. One of the interesting attempts is due to Liu et al. [Z. Liu, Y. Hu, X. Zhang, H. Ma, Certificateless signcryption scheme in the standard model, Information Sciences 180 (3) (2010) 452-464].
