We describe an efficient hash-based signature scheme that yields shorter signatures than the state of the art. Signing and verification are faster as well, and the overall scheme is suitable for constrained platforms typical of the Internet of Things. We describe an efficient implementation of our improved scheme and show memory, time, and energy consumption benchmarks over a real device, i.e. the ATmega1281 8-bit AVR micro controller embedded in MICAz, a typical sensor node used in wireless sensor networks.
