Nowadays, due to the rapid growth of Internet ofThings (IoT) towards technologies, the protection oftransmitted data becomes an important challenge.The devices of the IoT are very constrained resourcein terms of computing capabilities, energy andmemory capacities. Thus, the design of secure,efficient and lightweight crypto-systems becomesmore and more crucial. In this thesis, we have studiedthe problem of chaos based data security underreal-time and energy constraints. First, we havedesigned and implemented three pseudo-chaoticnumber generators (PCNGs). These PCNGs use aweak coupling matrix or a high diffusion binarycoupling matrix between chaotic maps and a chaoticmultiplexing technique. Then, we have realized threestream ciphers based on ...
