Chaotic encryption schemes are believed to provide a greater level of security than conventional ciphers. In this paper, a chaotic stream cipher is first constructed and then its hardware implementation details using FPGA technology are provided. Logistic map is the simplest chaotic system and has a high potential to be used to design a stream cipher for real-time embedded systems. The cipher uses...
Satellites are extensively used by public and private sectors to support a variety of services. Considering the cost and the strategic importance of these spacecrafts, it is fundamental to utilize strong cryptographic primitives to assure their security. However, it is of utmost importance to consider fault tolerance in their designs due to the harsh environment found in space, while keeping low area...
