摘要： Single-use authentication methods for accessing encrypted data stored on a protected volume of a computer are described, wherein access to the encrypted data involves decrypting a key protector stored on the computer that holds a volume-specific cryptographic key needed to decrypt the protected volume. Such single-use authentication methods rely on the provision of a key protector that can only be used once and/or that requires a new access credential for each use. In certain embodiments, a challenge-response process is also used as part of the authentication method to tie the issuance of a key protector and/or access credential to particular pieces of information that can uniquely identify a user.

摘要： A host operating system running on a computing device monitors network communications for the computing device to identify network resources that are requested by the computing device. The host operating system compares requested network resources against security policies to determine if the requested network resources are trusted. When an untrusted network resource is identified, the host operating system accesses the untrusted network resource within a container that is isolated from the host operating system kernel using techniques discussed herein. By restricting access to untrusted network resources to isolated containers, the host operating system is protected from even kernel-level attacks or infections that may result from an untrusted network resource.
