Signcryption Scheme

In this paper, a novel decentralized key-policy attribute-based signcryption (ABS) scheme is proposed, where each authority can generate secret-public key pair for the user independently without any cooperation and a centralized authority. In the proposed scheme, each authority can join or leave the system randomly without reinitializing the system,and issue secret-public keys to user respectively. Therefore, it is clear that the multi-authority attribute-based access control scheme can reduce the communication cost and the collaborative computing cost. Additionally, the attribute-based signcryption scheme is efficient in terms of both the identification authentication and the confidential communication, and can realize security secret sharing in cloud computing environments.

Authentication System

Authentication is the first and foremost security principle that involves validation of identity of an user or a machine. The successful authentication is required for authorization and secure data exchanges. A common classification of authentication system based on factors – something you know, something you own, something you did and something you are – is explained. Well-known and used password schemes employed in practice is described along with standards. A description Kerberos of authentication system based on symmetric key encryption and SSL based authentication which is based on public key encryption is given. Related Single-Sign-On technologies are explained. A brief overview of authentication for cloud computing, IoT and UIDAI is presented.

Multi-receiver encryption enables a sender to encrypt a message and transmit the ciphertext to a set of authorized users, while no one out this group of authorized users can decrypt the message. Multi-receiver encryption is of great importance in many sectors such as broadcast communication, cloud computing, wireless communications, networking applications, e-voting, lottery, and medical applications. This paper proposes an efficient multi-receiver public key encryption scheme based on Lucas sequences. The results of the computational analysis show that, projected scheme is better against renown attacks and prevailing anonymous multireceiver algorithms
