Abstract: The present invention relates to a shift register protected against physical attacks, comprising a coding module, a decoding module, a plurality of basic shift registers of which the respective inputs receive the bits of a codeword supplied by the coding module using an input bit at each clock cycle, and of which the respective outputs are connected to the decoding module in order to supply an output bit, with the codewords being chosen in such a way as to have the same non-zero Hamming weight and two successive codewords having a constant non-zero Hamming distance. The codewords are generated using an internal state machine and/or an external state machine to the coding module.

Abstract: A transmission/reception device with wake-up radio for a node with limited resources such as an IoT network node. The device includes a permanently powered auxiliary circuit, capable of detecting a wake-up token, and a main circuit, normally in the idle state and activated by the auxiliary circuit when a wake-up token is detected. The next wake-up token is calculated by the main circuit by applying a one-way function to at least part of a message exchanged on the main radio through a secure communication.

Abstract: This electronic device for signal processing with embedded optimization of electrical energy consumption includes: at least one sensor and at least one actuator; hardware for storing at least one correspondence table assigning a quality value to each pair formed by a state value measurable by each sensor and an action value adjustable by each actuator; processing hardware comprising an electrical energy consumption manager with a reinforcement learning engine designed to selectively choose between an exploitation and a random exploration in each correspondence table so as to select a new action and transmit it to each actuator. The learning reinforcement engine has a random exploration limit parameter, comprising an exploration distance value in each correspondence table, around a pre-selectable action value in each correspondence table.
