Efficient certificateless one-pass session key establishment protocols can be constructed from key encapsulation mechanisms (KEMs) by making use of tags and signcryption schemes. The resulting primitives are referred to as Certificateless Signcryption Tag Key Encapsulation Mechanisms (CLSC-TKEMs). In this paper we propose two novel CLSC-TKEM protocols, the first, named LSW-CLSC-TKEM, makes use ...

Multimedia Internet KEYing (MIKEY) is a standard key management protocol, used to set up common secrets between any two parties for multiple scenarios of communications. As MIKEY becomes widely deployed, it becomes worthwhile to not confine its applications to real-time or other specific applications, but also to extend the standard to other scenarios as well. For instance, MIKEY can be used to...

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 certificatele...

Signature can be used to verify the integrity of both a message and identity signer, whereas encryption ensure confidentiality message. In past, cryptography researchers have studied proposed numerous certificateless signcryption (CLSC) schemes combine benefits signature encryption. However, these may not robust enough withstand side-channel attacks. Through such attacks, an attacker constantly...
