Preview: Security and Privacy
summary
Preview lists concrete systems and attacks: papers use fully homomorphic encryption and garbled circuits but move heavy state and page faults into novel virtual-memory layers (Mage, DEEP) to make secure computation practical; an audio system claims metadata-private voice over fully untrusted infrastructure (Andras); several blockchain papers build off-chain execution and a faster batching engine for public ledgers (RoomBlocks, off-chain execution); memory-leakage through Intel SGX enclaves and countermeasures appear, plus a tool that finds consensus faults using multi-transaction differential fuzzing and Icarus that empirically breaks LEO network stacks.
