Abstract

We propose a very low-cost authentication scheme based on Merkle signatures, which does not require any computation on the prover side, but instead, has moderate memory requirements. Our technique is particularly attractive on platforms where memory is already available, since it can be implemented at practically no cost, without any CPU, and with an extremely simple memory access control mechanism.
