Improve Security Key Schedule Algorithm of PRESENT Block Cipher by Using Diffusion Layer AES Algorithm
摘要
Robust encryption techniques are essential for guaranteeing data security in the rapidly developing field of cryptography. The two main focuses of network and service providers are the data and the network's security. Therefore, to safeguard the data during various exchanges, cryptographic techniques are used during the data transmission. On the other hand, attackers are aware of the answer, and conventional cryptography techniques are widely recognized. As a result, a novel approach to cryptography is needed, one that increases the complexity and security of the data cipher. Due to growing security concerns, this approach has become increasingly important in computer technologies for transportation, banking, healthcare, and other Internet of Things (IoT)-based applications. This work introduces a hybrid cryptographic algorithm that combines the PRESENT method with the Advanced Encryption Standard (AES) diffusion layer to improve security and efficiency. The lightweight, highly secure PRESENT method, well-known for its effectiveness in limited environments like IoT devices, complements AES, a symmetric key encryption algorithm commonly utilized for its performance and resilience. The results of the experiments demonstrate that the hybrid algorithm can secure data with low overhead, making it a good fit for contemporary security needs across a wide range of application areas. This paper shows the advantages and possible uses of combining AES with PRESENT, which advances the development of more effective and safe encryption techniques.
