A Case Study on Covert Channel Establishment via Software Caches in High-Assurance Computing Systems
Covert channels can be utilized to secretly deliver information from high privileged processes to low privileged processes in the context of a high-assurance computing system. In this case study, we investigate the possibility of covert channel estab
