In recent years, blockchain has gained widespread attention as an emerging technology for
decentralization, transparency, and immutability in advancing online activities over public …

We present VC3, the first system that allows users to run distributed MapReduce
computations in the cloud while keeping their code and data secret, and ensuring the …

Intel SGX, a new security capability in emerging CPUs, allows user-level application code to
execute in hardwareisolated enclaves. Enclave memory is isolated from all other software …

Security architectures such as Intel SGX need protection against rollback attacks, where the
adversary violates the integrity of a protected application state by replaying old persistently …

Exploiting memory disclosure vulnerabilities like the HeartBleed bug may cause arbitrary
reading of a victim's memory, leading to leakage of critical secrets such as crypto keys …

A smart contract on a blockchain cannot keep a secret because its data is replicated on all
nodes in a network. To remedy this problem, it has been suggested to combine blockchains …

This paper presents the first critical analysis of building highly secure, performant, and
confidential Byzantine fault-tolerant (BFT) consensus by integrating off-the-shelf crash fault …

Public cloud platforms have leveraged Trusted Execution Environment (TEE) technology to
provide confidential computing services. However, TEE-protected applications still suffer …

Protected-module architectures such as Intel SGX provide strong isolation guarantees to
sensitive parts of applications while the system is up and running. Unfortunately systems in …

Trusted execution environments (TEEs) are becoming a requirement across a wide range of
platforms, from embedded sensors to cloud servers, which encompass a wide range of cost …
