摘要： According to various embodiments of the invention, a system and method for controlling a file system. In some embodiments, a control plane interposes between a data plane user and a data plane, intercepts file system operations, and performs control plane operations upon the file system operations. In one such embodiment, the system and method is implemented between a data plane user that is a local file system user and a data plane that is a local file system. In another such embodiment, the system and method is implemented between a data plane user that is a client and a data plane that is a file server. Furthermore, for an embodiment where the control plane that interposes between a client and a file server, the control plane can be implemented as a file system proxy. Control plane operations include, but are not limited to, observation, verification, and transformation of a file system operation.

摘要： A non-transitory computer-readable storage medium storing a set of instructions executable by a processor. The set of instructions is operable to receive a request from a node to join a trusted ad hoc network. The set of instructions is further operable to authenticate the node to join the trusted ad hoc network. The authentication is performed based on a verification that the node will comply with a security policy of the trusted ad hoc network. The set of instructions is further operable to send, to the node, a verification that the trusted ad hoc network complies with the security policy. The set of instructions is further operable to add the node to the trusted ad hoc network.

摘要： A system and method of providing trusted service transactions includes associating a commitment with a remote service. The commitment includes a trusted list of runtime dependencies to execute a transaction. The method includes monitoring an actual list of runtime dependencies invoked during execution of the transaction using a trusted monitor. Execution is blocked if a deviation of the actual list from the trusted list is detected. Therefore, a completed transaction is allowed only if no deviation is found between the trusted and invoked list of runtime dependencies. A certificate authority in cooperation with software vendors preferably provide a signed commitment. The commitment is delivered by the provider to a user upon request and verified by the requester. The transaction is then executed by the user. Therefore, trust is verified before and during the transaction and privacy of data is guaranteed after completion.
摘要翻译：提供可信服务事务的系统和方法包括将承诺与远程服务相关联。承诺包括执行事务的运行时依赖关系的受信任列表。该方法包括使用可信监视器监视在执行事务期间调用的运行时依赖关系的实际列表。如果检测到实际列表与受信任列表的偏差，则执行被阻止。因此，只有在受信任和调用的运行时依赖关系列表之间没有发现偏差的情况下，才允许完成的事务。与软件供应商合作的认证机构最好提供签署的承诺。承诺由供应商根据请求提供给用户并由请求者验证。然后由用户执行事务。因此，在交易之前和期间对信任进行了验证，完成后保证数据的隐私。

摘要： The subject disclosure presents a novel technique for balancing the tradeoff between security monitoring and energy consumption on mobile devices. Security/energy tradeoffs for host-based detectors focusing on rootkits are analyzed along two axes: a scanning frequency, and a surface of attack. Experimental results are applied to a hypervisor-based framework, and a sweet spot is identified to minimize both energy consumption and a window of vulnerability for critical operating system objects such as code pages and kernel data.

摘要： A system and method is disclosed which may comprise receiving, via a computing device, from a first user having a first personal device, a request for sharing access to a resource or a state of a second personal device of a second user, the first user and second user having an on-line social network relationship; and determining whether to grant sharing access to the one of the resource and the state of the second personal device of the second user. Determining whether to grant sharing access may be based, at least in part, upon the nature of the on-line social network relationship. The method and apparatus may comprise registering, via the computing device, an ownership link for a personal device and an owner having a certified identity within the social network; storing the ownership link; and utilizing the ownership link for determining whether to grant sharing access.
