Most of the current aggregate signcryption schemes based on bilinear pairings have low
computational efficiency, thus they are not suitable for the application environment with …

Signcryption is a cryptography primitive which can provide message confidentiality and
sender authentication in a single logic step. In order to improve computational efficiency of …

These existed signcryption schemes have low aggregate signcryption efficiency. So in this
paper, we propose a new certificateless aggregate signcryption scheme. The new method …

The research on aggregate signcryption is mostly based on identity-based encryption to
provide confidentiality and authentication, thus improving efficiency. But aggregate …

The traditional certificateless aggregation signcryption scheme (CLASC) scheme has low
computational efficiency and time-consuming. Therefore, this paper proposes a novel …

A formal model of certificateless aggregate signcryption is proposed, which allows n different
users to signcrypt n different messages. Then we propose a concrete certificateless …

Signcryption is basically a cryptographic primitive which provides both signature and
encryption functions simultaneously, but it is not useful when only one of the function is …

In order to more effectively protect the security of network information, confidentiality and
authentication of message need to be realized at the same time. Signcryption performs …

Aggregate signcryption could verify the multiple messages via a single operation. Most of
the identity-based aggregate signcryption are based on random oracle. To exploit the …

The concept of aggregate signcryption was first introduced in 2009 by Selvi et al.[Identity
based aggregate signcryption schemes, Lecture Notes in Computer Science 5922 LNCS …
