Dr. Emad AbdulZahra Mohammed and Miss. Israa Mohammed Qasim published a paper entitled (Security augmenting of optical cryptosystem based on linear canonical transform domain using a full phase encoding technique) in the Physica Scripta, which is indexed in Scopus/Web of Science database. the study aims to present a novel method for optical security and cryptographic systems. In this proposal, we use a fully phase encoding technique to augment the security of encryption system in the linear canonical transform
