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