Grille (cryptography)

Grille is a lightweight cryptographic algorithm designed for applications requiring efficient encryption and decryption processes, particularly in environments with limited resources such as Internet of Things (IoT) devices. It was designed by a team led by Thomas Peyrin in 2018 and is notable for its balanced approach, offering both security and performance. The algorithm operates on a block structure, processing data in fixed-size blocks, and utilizes a combination of substitution and permutation operations to achieve confidentiality.
