摘要： End-to-end security between clients and a server, and traffic visibility to intermediate network devices, achieved through combined mode, single pass encryption and authentication using two keys is disclosed. In various embodiments, a combined encryption-authentication unit includes a cipher unit and an authentication unit coupled in parallel to the cipher unit, and generates an authentication tag using an authentication key in parallel with the generation of the cipher text using an encryption key, where the authentication and encryption key have different key values. In various embodiments, the cipher unit operates in AES counter mode, and the authentication unit operates in parallel, in AES-GMAC mode Using a two key, single pass combined mode algorithm preserves network performance using a limited number of HW gates, while allowing an intermediate device access to the encryption key for deciphering the data, without providing that device the ability to compromise data integrity, which is preserved between the end to end devices.

摘要： Both end-to-end security and traffic visibility may be achieved by a system using a controller that derives a cryptographic key that is different for each client based on a derivation key and a client identifier that is conveyed in each data packet. The controller distributes the derivation key to information technology monitoring devices and a server to provide traffic visibility. The key may be derived using a cryptographic one way function and a client identifier so that end-to-end security may be achieved.

摘要： A measurement engine generates an integrity manifest for a software program and uses it to perform active platform observation. The integrity manifest indicates an integrity check value for a section of the program's code. The measurement engine computes a comparison value on the program's image in memory and determines if the comparison value matches the expected integrity check value. If the values do not match, the program's image is determined to be modified, and appropriate remedial action may be triggered.

摘要： A method that includes initiating a network access request from an access requester on a platform that couples to a network, the network access request made to a policy decision point for the network. The method also includes establishing a secure communication channel over a communication link between the policy decision point and a policy enforcement point on the platform. Another secure communication channel is established over another communication link. The other communication link is between at least the policy enforcement point and a manageability engine resident on the platform. The manageability engine forwards posture information associated with the access requester via the other secure communication channel. The posture information is then forwarded to the policy decision point via the secure communication channel between the policy enforcement point and the policy decision point. The policy decision point indicates what access the access requester can obtain to the network based on a comparison of the posture information to one or more network administrative policies.
