Private Computing on Public Platforms (PCPP) is a new technology designed to enable secure and private execution of applications on remote, potentially hostile, public platforms. PCPP uses a host assessment to validate a host’s hardware and software configuration and then uses applied encryption techniques embedded in the operating system to isolate the protected application allowing its executable code, context, and data to remain unaltered, unmonitored, and unrecorded before, during, and after execution. PCPP must secure its encryption keys to ensure that the application isolation is robust and reliable. In this paper we offer a detailed description of the PCPP Key Protection scheme including its architecture, PCPP Key Protection security analysis, and a discussion of the performance overhead associated with using PCPP Key Protection.
