Abstract:
Due to the proliferation of connected devices, the development of secured and low-resource cryptographic systems has become a real challenge. In fact, ciphering algorithms have not been thought to be implemented on embedded platforms with limited computing, memory and energy resources. This paper addresses a hardware implementation of a chaos-based stream cipher is initially optimized for software. First, the structure of the cipher is investigated. Then, its hardware implementation on a Zynq7000 platform is proposed considering both throughput performance and logic resources usage. The proposed design is compared to hardware implementations of existing stream ciphers including chaos-based ones, ac{aes}, Rabbit, Salsa20 and Trivium.
