Query: Secure Remote Attestation with Strong Key Insulation Guarantees   Recent years have witnessed a trend of secure processor design in both
academia and industry. Secure processors with hardware-enforced isolation can
be a solid foundation of cloud computation in the future. However, due to
recent side-channel attacks, the commercial secure processors failed to deliver
the promises of a secure isolated execution environment. Sensitive information
inside the secure execution environment always gets leaked via side channels.
This work considers the most powerful software-based side-channel attackers,
i.e., an All Digital State Observing (ADSO) adversary who can observe all
digital states, including all digital states in secure enclaves. Traditional
signature schemes are not secure in ADSO adversarial model. We introduce a new
cryptographic primitive called One-Time Signature with Secret Key Exposure
(OTS-SKE), which ensures no one can forge a valid signature of a new message or
nonce even if all secret session keys are leaked. OTS-SKE enables us to sign
attestation reports securely under the ADSO adversary. We also minimize the
trusted computing base by introducing a secure co-processor into the system,
and the interaction between the secure co-processor and the attestation
processor is unidirectional. That is, the co-processor takes no inputs from the
processor and only generates secret keys for the processor to fetch. Our
experimental results show that the signing of OTS-SKE is faster than that of
Elliptic Curve Digital Signature Algorithm (ECDSA) used in Intel SGX.
