Encryption methods

Random numbers are a crucial component of any encryption activity in modern cryptography. Quantum Random Number Generators (QRNGs) produce truly random output strings to replace pseudo-random ones. In this research, the author’s team centered on investigating and scrutinizing the design of a QRNG utilizing optical methods tailored to meet cryptographic standards.

With the rise of the Internet of Things (IoT), the risk of information security is increasing. There have been many proposals for IoT security, however, so far, there is not truly effective and comprehensive solution. The study aims at lightweight encryption, with the basic goal of reducing the loops of encryption algorithms, reducing the computing requirements, and energy consumption of the system while ensuring safety, and integrating into new Protocols of IoT networks and weak resource devices.

This paper proposes a block crypto system that uses cyclic geometric progressions over polynomial rings as encryption function, and its encryption diagram is based on unbalanced Feistel network with four branches. All the sub keys in encryption steps are also elements in cyclic geometric progressions over polynomial ring with two cyclotomic cosets. By using this crypto system, we apply to a hash function with 512 bits output length. Some diffusion simulations of the proposed crypto system and hash function are also presented.

In this paper we propose a new method to manage secure group using binomial key tree approach. We show that number of encryptions performed and rekey messages constructed during membership change are less compared to the scheme proposed by Wong and others. In our scheme, it is not required to balance the tree after membership change.
