We present Path ORAM, an extremely simple Oblivious RAM protocol with a small amount of
client storage. Partly due to its simplicity, Path ORAM is the most practical ORAM scheme …

Cloud services have revolutionized modern computing. The benefits of outsourcing data and
computation come with security and privacy concerns. This monograph explores the …

Oblivious RAM (ORAM), first introduced in the ground-breaking work of Goldreich and
Ostrovsky (STOC'87 and J. ACM'96) is a technique for provably obfuscating programs' …

摘要批处理, 流式计算和机器学习等分布式的大数据计算环境在云上的广泛部署与应用,
为云用户带来了极大的便利, 但随之带来的隐私数据泄露事件愈演愈烈. 如何在这种云上部署的 …

Hardware enclaves such as Intel SGX are a promising technology for improving the security
of databases outsourced to the cloud. These enclaves provide an execution environment …

We present PANCAKE, the first system to protect key-value stores from access pattern
leakage attacks with small constant factor bandwidth overhead. PANCAKE uses a new …

Existing oblivious storage systems provide strong security by hiding access patterns, but do
not scale to sustain high throughput as they rely on a central point of coordination. To …

We consider oblivious storage systems hiding both the contents of the data as well as
access patterns from an untrusted cloud provider. We target a scenario where multiple users …

Hiding memory access patterns is required for secure computation, but remains prohibitively
expensive for many interesting applications. Prior work has either developed custom …

This paper presents the design and implementation of Obladi, the first system to provide
ACID transactions while also hiding access patterns. Obladi uses as its building block …
