While advanced encryption standard (AES) is extensively in use in a number of applications, its area cost limits its deployment in resource constrained platforms. In this letter, we have implemented SIMON, a recent promising low-cost alternative of AES on reconfigurable platforms. The Feistel network, the construction of the round function and the key generation of SIMON, enables bit-serial hardware...
Cryptography algorithms are ranked by their speed in encrypting/decrypting data and their robustness to withstand attacks. Real-time processing of data encryption/decryption is essential in network based applications to keep pace with the input data inhalation rate. The encryption/decryption steps are computationally intensive and exhibit high degree of parallelism. Field programmable gate arrays...
State-of-the-art Field Programmable Gate Arrays (FPGAs) have inspired the innovation of hardware/software co-design methodologies that provide a high-level of abstraction in the design process. In this paper, we explore the effectiveness of a formal methodology in the co-design of parallel versions of the Rijndael cryptographic algorithm. The investigated methodology employs the functional paradigm...
