WebA bit field is a data structure that holds a sequence of bits. They are sometimes referred to as “flags” and are typically used to store the intermediate state or outcome of a set of operations in embedded devices and microprocessors. They are useful data structures when you want to optimise for space. WebIn this work, we used a sensor-based True Random Number Generator in order to generate keys for a stream cipher based on a recently published hybrid algorithm mixing Skew Tent Map and a Linear Feedback Shift Register. The stream cipher was implemented and tested in a Field Programmable Gate Array (FPGA) and was able to generate 8-bit width data …
