side-channel cache attacks
2018/6/25
The ARM TrustZone is a security extension which is used in recent Samsung flagship smartphones to create a Trusted Execution Environment (TEE) called a Secure World, which runs secure processes (Trust...
Drive-by Key-Extraction Cache Attacks from Portable Code
Side-channel attack cache attack web page confinement
2018/2/1
We show how malicious web content can extract cryptographic secret keys from the user's computer. The attack uses portable scripting languages supported by modern browsers to induce contention for CPU...
In modern computing environments, hardware resources are commonly shared, and parallel computation is widely used. Parallel tasks can cause privacy and security problems if proper isolation is not enf...

Cloud services keep gaining popularity despite the security concerns. While non-sensitive data is easily trusted to cloud, security critical data and applications are not. The main concern with the cl...
Multi-processor systems are becoming the de-facto standard
across different computing domains, ranging from high-end
multi-tenant cloud servers to low-power mobile platforms.
The denser integration...

AES side channel access-based cache-attacks
2010/11/26
In this paper we analyze the case of AES and present an attack which is capable of recovering the full secret key in almost realtime for AES-128, requiring only a very limited number of observed encry...
Cache Attacks and Countermeasures: the Case of AES
side-channel attack cache memory access cryptanalysis
2009/2/25
We describe several software side-channel attacks based on inter-process leakage through the state of the CPU’s memory cache. This leakage reveals memory access patterns, which can be used for cryptan...
