# Hardware Implementation of Lightweight Chaos-Based Stream Cipher _by Le Glatin Maguy (IETR-VAADER) - 2019.09.19_ ###### tags: `VAADER` `Seminar` ![](https://i.imgur.com/qHaIBij.gif) ## Abstract Due to the proliferation of connected devices, thedevelopment of secured and low-resource cryptographic systemshas become a real challenge. In fact, ciphering algorithms havenot been thought to be implemented on embedded platforms withlimited computing, memory and energy resources. My internship consists of designing a hardware implementation of a LightWeight Chaos-Based Stream Cipher (LWCB SC) previously developped for software. A stream cipher is a cryptographic system where the output is obtained by performing a XOR between the input of the cipher and the output of a random number generator. My work is espescially focused on the implementation of this random number generator.!
