Secure IP-block distribution for hardware devices

EDA vendors have proposed a standard for the sharing of IP among vendors to be used in the design and development of IP for FPGAs. Although, we do not propose any attacks, we show that there are easy ways in which the security of the whole process can be enhanced by using standard cryptographic techniques such as secret sharing and public key based key exchange. We also explore the advantages that newer primitives have such as all-or-nothing transforms and physical unclonable functions. We show that the protocols proposed would significantly reduce the effects that the leakage of a single key would have over the whole system.
