In this paper, we propose a family of lightweight block ciphers CHAM that has remarkable efficiency on resource-constrained devices. The family consists of three ciphers, CHAM-64/128, CHAM-128/128, and CHAM-128/256 which are of the generalized 4-branch Feistel structure based on ARX (Addition, Rotation, XOR) operations.
