Shielding applications from an untrusted cloud with Haven

June 16, 2016 ~ Adrian Colyer ~ 5 Comments

Shielding applications from an untrusted cloud with Haven Baumann et al. OSDI 2014 Our objective is to run existing server applications in the cloud with a level of trust and security roughly equivalent to a user operating their own hardware in a locked cage at a colocation facility. We're all familiar with the idea of ... Continue Reading
