Flush Code Eraser: Fast Attack Response Invalidating Cryptographic Sensitive Data

Flush+Flush: A Fast and Stealthy Cache Attack

Research on cache attacks has shown that CPU caches leak significant information. Proposed detection mechanisms assume that all cache attacks cause more cache hits and cache misses than benign applications and use hardware performance counters for detection. In this article, we show that this assumption does not hold by developing a novel attack technique: the Flush+Flush attack. The Flush+Flus...

Enhanced Flush+Reload Attack on AES

In cloud computing, multiple users can share the same physical machine that can potentially leak secret information, in particular when the memory de-duplication is enabled. Flush+Reload attack is a cache-based attack that makes use of resource sharing. T-table implementation of AES is commonly used in the crypto libraries like OpenSSL. Several Flush+Reload attacks on T-table implementat...

Flush+Flush: A Stealthier Last-Level Cache Attack

Research on cache attacks has shown that CPU caches leak significant information. Proposed detection mechanisms assume that all cache attacks cause more cache hits and cache misses than benign applications and use hardware performance counters for detection.

Efficient Cryptographic Access Control Protocol for Sensitive Data Management

--In view of sensitive data management, an efficient cryptographic access control scheme is proposed. Based on attribute-based encryption, the proposed scheme not only inherits flexibility and fine-grained access control for users, but also realizes cryptographic management for servers. In additional, the scheme alleviates the administering burdens on the server, and handle dynamic access polic...
