Abstract
Apparatuses and methods associated with configurable crypto hardware engine are disclosed herein. In embodiments, an apparatus for signing or verifying a message may comprise: a hardware hashing computation block to perform hashing computations; a hardware hash chain computation block to perform successive hash chain computations; a hardware private key generator to generate private keys; and a hardware public key generator to generate public keys, including signature generations and signature verifications. The hardware hashing computation block, the hardware hash chain computation block, the hardware private key generator, and the hardware public key generator may be coupled to each other and selectively cooperate with each other to perform private key generation, public key generation, signature generation or signature verification at different points in time. Other embodiments may be disclosed or claimed.
