Executive Summary

The authors present a new block cipher LED. While dedicated to compact hardware implementation, and offering the smallest silicon footprint among comparable block ciphers, the cipher has been designed to simultaneously tackle three additional goals; they explore the role of an ultra-light (in fact non-existent) key schedule, they consider the resistance of ciphers, and LED in particular, to related-key attacks: they are able to derive simple yet interesting AES-like security proofs for LED regarding related- or single-key attacks and while they provide a block cipher that is very compact in hardware, they aim to maintain a reasonable performance pro le for software implementation.
