Some New Topics in Cryptography: Essentials and Applications

Over the past decades, cryptography has always been a concern for both scientific and industrial researchers. The rapid growth in the field of information technology, along with the introduction of new concepts such as the Internet of Objects, as well as the growing range of users and a variety of new Internet services (such as social networks, cloud services, etc.), have created many challenges and consequently new security criteria are needed. This has led to the rapid growth of cryptographic science. The main purpose of this article is to introduce new approaches in the field of modern cryptography which either provide some new concepts or take significant steps to improve previous efforts. Accordingly, this paper follows three objectives 1. Emphasizing the need to identify and review new cryptographic issues; 2. Clarifying some of the new cryptographic aspects by studying some of the most important developments in cryptography in recent years; 3. Reviewing briefly some of the latest issues and concepts considering future cryptographic orientations.
