Energy-Efficient Extended Present-128 Cipher for Internet of Things and Wireless Sensor Network Security

Abstract

Cryptography is essential in many digital fields to provide information security and confidentiality. Thus, many digital services, such as those that transfer sensitive data, require encryption using a lightweight block cipher such as PRESENT, which is an ultra-lightweight encryption algorithm. However, this algorithm has weaknesses; for this reason, we propose in this paper an extended version of the PRESENT algorithm based on a substitution-permutation network and the Alfa function. Additionally, the proposed algorithm exhibits the Strict Avalanche Criterion, reaching 50% in the 2nd round, exceeding PRESENT, which reaches 50% in the 6th round, while ensuring high safety.
