Certificateless Aggregate Signcryption Schemes

Ziba Eslami and Nasrollah Pakniat

Abstract

The concept of an aggregate signcryption scheme was first introduced in 2009 by Selvi S.S.D. et. al. in the identity-based setting. The aggregation process of these schemes reduces the amount of exchanged information and is particularly useful in low-bandwidth communication networks and computationally-restricted environments. In this paper, we define a suitable security model for certificateless aggregate signcryption schemes and propose an example which we prove is secure in the random oracle model under the gap Bilinear Diffie-Hellman and computational Diffie-Helman intractability assumptions.
