ID based generalized signcryption

Sunder Lal and Prashant Kushwah

Abstract: Generalized signcryption is a new cryptographic primitive in which a signcryption scheme can work as an encryption scheme as well as a signature scheme. This paper presents an identity based generalized signcryption scheme based on bilinear pairing and discusses its security for message confidentiality non repudiation and ciphertext authentication.

Category / Keywords: public-key cryptography / bilinear pairings, identity based cryptography, signcryption, generalized signcryption.
