    Abstract: Procedures for resumption from a low activity condition are discussed. In implementations, a persistent state file, or a portion thereof, is secured via an encryption algorithm, with the decryption key secured via the operating system (OS) login user credentials. Once a user is authenticated via the OS login, the persistent state file may be decrypted and inserted in the OS boot path with resumption occurring through the persistent state file.

    Abstract: Tools and techniques for securely launching encrypted operating systems are described herein. The tools may provide computing systems that include operating systems (OSs) that define boot paths for the systems. This boot path may include first and second OS loader components. The first loader may include instructions for retrieving a list of disk sectors from a first store, and for retrieving these specified sectors from an encrypted second store. The first loader may also store the sectors in a third store that is accessible to both the first and the second loader components, and may invoke the second loader to try launching the OS using these sectors. In turn, the second loader may include instructions for retrieving these sectors from the third store, and for unsealing a key for decrypting these sectors. The second loader may then decrypt these sectors, and attempt to launch the OS from these sectors.
