Secure Encrypted Virtualization is Unsecure

Understand

Virtualization has become more important since cloud computing is getting more and more popular than before.

• There is an increasing demand for security among the cloud customers.
• AMD plans to provide Secure Encrypted Virtualization (SEV) technology in its latest processor EPYC to protect virtual machines by encrypting its memory but without integrity protection.
• In this paper, we analyzed the weakness in the SEV design due to lack of integrity protection thus it is not so secure.
