Generalization of Barreto et al ID based Signcryption Scheme
Sunder Lal and Prashant Kushwah
Abstract: This paper presents an efficient and provable secure identity based generalized signcryption scheme based on  which can work as signcryption scheme, encryption scheme and signature scheme as per need. Its security is proved under the difficulty of q-BDHIP. A generalized signcryption scheme in multiple PKGs environment is also proposed.
Category / Keywords: public-key cryptography / ID based signcryption, generalized signcryption and multiple PKGs environment.
