Abstract
The PRINCE lightweight cryptographic algorithm was introduced as a template in 2012. In this paper, we intend to change the structure of the PRINCE encryption algorithm and use a Dynamic S-BOX to increase the complexity and security of the encryption process. In order to show the efficiency of the proposed structure, differential analysis is performed on the algorithm as well as analysis on the optimal number of revolutions for the algorithm. Analyzes and implementations show that the cryptographic structure is more complex. Despite the slight increase in memory and execution time of the algorithm, compared to the PRINCE encryption algorithm with fixed S-BOX, it has more strength against differential attack and as a result, the security in the improved algorithm has increased. Stronger also increases security.
