Hybrid aggregated signcryption scheme using multi-constraints differential evolution algorithm for security.

Recently, information security suited for a comprehensive number of practical applications and which mainly affected by an end-to-end security. Earlier works on information security have concentrated on protecting messages rather than aggregating whether the message reliability. In order to overcome these drawbacks, in this paper, a hybrid aggregated signcryption (HAS) scheme is proposed that uses the efficient key encapsulation mechanism (KEM) and data encapsulation mechanism (DEM). The KEM utilizes the modified version of Kurosawa and Desmedt hashing scheme to encapsulate the key. The DEM utilizes the elliptic curve cryptography (ECC) algorithm to encapsulate the message. The multi-constraints differential evolution (MDE) algorithm used to select optimal prime fields in ECC algorithm. Furthermore, an aggregated signature scheme used to aggregate many signatures on many messages from many distinct singers into one single signature, which minimizes the verification cost. The proposed HAS scheme achieves reliability and unforgeablity rather than existing schemes. [ABSTRACT FROM AUTHOR]
