商品簡介
One of the most important communication technologies of our day is the Internet of Things. The IoT system faced issues with device power consumption, battery life, memory space, and cost of performance as a result of this advancement and expansion of IoT devices. Encryption algorithms are one of the most crucial ways to guarantee the confidentiality of data while it is being transmitted. The Advanced Encryption Standard is one of the most popular encryption algorithms. In this book, the Tiny Advanced Encryption Standard algorithm has been proposed with several possibilities to improve the AES algorithm's encryption speed and flexibility when used for small data. It is also proposed to achieve a high level of encryption and reduce the complexity of the algorithm. Using the MATLAB program, the performance of the proposed algorithm was compared to that of the original AES algorithm on texts and images. The results showed that the proposed algorithm reduced the time required for encryption and decryption. It is interesting to note that the proposed algorithm was able to encrypt data from 4 bytes to a significant amount of bytes for text and images.
