Abstract: Technologies for elliptic curve cryptography (ECC) include a computing device having an ECC engine that reads one or more parameters from a data port. The ECC engine performs operations using the parameters, such as an Elliptic Curve Digital Signature Algorithm (ECDSA). The ECDSA may be performed in a protected mode, in which the ECC engine will ignore inputs. The ECC engine may perform the ECDSA in a fixed amount of time in order to protect against timing side-channel attacks. The ECC engine may perform the ECDSA by consuming a uniform amount of power in order to protect against power side-channel attacks. The ECC engine may perform the ECDSA by emitting a uniform amount of electromagnetic radiation in order to protect against EM side-channel attacks. The ECC engine may perform the ECDSA verify with 384-bit output in order to protect against fault injection attacks.

Abstract: Technologies for elliptic curve cryptography (ECC) include a computing device having an ECC engine that reads a datapath selector signal that indicates a 256-bit data width or a 384-bit data width. The ECC engine reads one or more parameters having a data width indicated by the datapath selector signal from a data port. The ECC engine reads an opcode from an instruction port that identifies an ECC operation such as an elliptic curve operation or a prime field arithmetic operation. The ECC engine performs the operation with the data width identified by the datapath selector. The ECC engine writes results data having the data width identified by the datapath selector to one or more output ports. The ECC engine may perform the elliptic curve operation with a specified side-channel protection level. The computing device may include a cryptography driver to control the ECC engine. Other embodiments are described and claimed.

Abstract: An attestation protocol between a prover device (P), a verifier device (V), and a trusted third-party device (TTP). P and TTP have a first trust relationship represented by a first cryptographic representation based on a one-or-few-times, hash-based, signature key. V sends an attestation request to P, with the attestation request including a second cryptographic representation of a second trust relationship between V and TTP. In response to the attestation request, P sends a validation request to TTP, with the validation request being based on a cryptographic association of the first trust relationship and the second trust relationship. TTP provides a validation response including a cryptographic representation of verification of validity of the first trust relationship and the second trust relationship. P sends an attestation response to V based on the validation response.
