The public Infrastructure-as-a-Service (IaaS) cloud industry has reached a critical mass in
the past few years, with many cloud service providers fielding competing services. Despite …

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

Blockchains and more general distributed ledgers are becoming increasingly popular as
efficient, reliable, and persistent records of data and transactions. Unfortunately, they ensure …

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 …

Recently, many fruitful results have been presented in text information hiding such as text
format-based, text image-based method and so on. However, existing information hiding …

Free cloud-based services are powerful candidates for deploying ubiquitous encryption for
messaging. In the case of email and increasingly chat, users expect the ability to store and …

Mobile devices today have been increasingly used to store and process sensitive
information. To protect sensitive data, mobile operating systems usually incorporate a …

Motivated by the problem of data breaches, we formalize a notion of security for dynamic
structured encryption (STE) schemes that guarantees security against a snapshot adversary; …

A plausibly deniable storage (PDS) system not only conceals the plaintext of sensitive data,
but also hides their very existence. It can essentially mitigate a novel coercive attack, in …

Plausibly-deniable (PD) storage systems allow users to securely hide data and plausibly
deny its presence when challenged by adversaries who coerce them to provide encryption …
