===== Secure Encrypted Virtualization (SEV) =====
[[dido:public:ra:xapend:xapend.a_glossary:start| Return to Glossary ]]

**Secure Encrypted Virtualization (SEV)** integrates  main  memory  encryption  capabilities  with  the 
existing AMD-V virtualization architecture to support encrypted virtual machines.  Encrypting virtual machines 
can  help  protect  them  not  only  from  physical  threats  but  also  from  other  virtual  machines  or  even  the 
[[dido:public:ra:xapend:xapend.a_glossary:h:hypervisor]] itself.  SEV thus represents a new virtualization security paradigm that is particularly applicable to 
cloud  computing  where  virtual  machines  need  not  fully  trust  the  hypervisor  and  administrator  of  their  host 
system.  As with [[dido:public:ra:xapend:xapend.a_glossary:s:secme]], no application software modifications are required to support SEV.
