Side-Channels and Runtime Encryption Solutions with Intel® SGX
It is important to be aware that side-channels exist in any digital system, not just SGX. The interest in side-channels attacks in the context of SGX arises because many kinds of attacks that are possible in conventional computing environments are no longer possible in SGX, leaving side-channel attacks as one of few remaining attack vectors.
This White Paper briefly explains side-channel attacks, then discusses some specific side-channel attack techniques in the context of SGX and ways of defending against those attacks. This paper also describes various defenses used by the Fortanix Self-Defending Key Management Service™ (SDKMS) and by Fortanix Runtime Encryption solutions to protect against side-channel attacks.
In this White Paper you will learn:
-
Introduction to side-channel Attacks
-
Example of side-channel Attacks
-
Sources of side-channels
-
Mitigation Strategies
-
Promise of Intel® SGX
