cryptographic protocols secure multiparty computation
2018/8/21
Protocols for secure multiparty computation enable a set of parties to compute a joint function of their inputs, while preserving \emph{privacy}, \emph{correctness} and more. In theory, secure computa...
3PC ORAM with Low Latency, Low Bandwidth, and Fast Batch Retrieval
secure computation multi-party computation (MPC) oblivious RAM (ORAM)
2018/4/17
Multi-Party Computation of Oblivious RAM (MPC ORAM) implements secret-shared random access memory in a way that protects access pattern privacy against a threshold of corruptions. MPC ORAM enables sec...
Anonymity Trilemma: Strong Anonymity, Low Bandwidth, Low Latency---Choose Two
Strong Anonymity Low Bandwidth
2017/9/29
This work investigates the fundamental constraints of anonymous communication (AC) protocols. We analyze the relationship between bandwidth overhead, latency overhead, and sender anonymity or recipien...
ECDH Key-Extraction via Low-Bandwidth Electromagnetic Attacks on PCs
side-channel attack elliptic curve cryptography electromagnetic emanations
2016/2/23
We present the first physical side-channel attack on elliptic curve cryptography running on a PC. The attack targets the ECDH public-key encryption algorithm, as implemented in the latest version of G...
Many computers emit a high-pitched noise during operation, due to vibration in some of their electronic components. These acoustic emanations are more than a nuisance: they can convey information abou...
