| Resumen |
Since the arrival of devices connected to the Internet, cryptographic goals have become a constant challenge for cybersecurity specialists. Data transmitted between IoT devices can become sensitive depending on the application scenario, which makes it necessary to consider efficient algorithmic implementations if they are used to achieve cryptographic goals on such constrained resource devices. This article presents a performance evaluation of different implementations of block cipher algorithms in devices with ARM architecture. For this purpose, the block encryption algorithms AES, 3DES, CAST5, RC2, Blowfish, Camellia, and SM4 were considered in the 5 modes of operation for confidentiality: ECB, CBC, OFB, CFB and CTR. Our results indicate to us that the AES, Blowfish, and Camellia implementations are the fastest for encrypting and decrypting, with Camellia being the implementation that requires the least amount of memory. In contrast, 3DES and RC2 show slower implementations and higher memory consumption, which makes it possible to suggest implementations of the AES and Camellia algorithms for use in IoT ecosystems. © 2024 IEEE. |
