Overview of Memory Security Technologies

Recently, a concept of confidential computing has been introduced in cloud computing [1] . One of its key feature is protection of "Data in use". "Data in use" means the data on the main memory while the data is being processed. Memory encryption capability equipped with current main stream processors contributes above objective. Few cloud vendors started confidential computing services utilizing memory encryption feature with AMD SEV (Secure Encrypted Virtualization) [2] , [3] . In this presentation, overview of threats and mitigating technologies about main memory security is introduced.
