    摘要： Cryptographic access control of multimedia video is presented. A method includes generating as metadata an access control policy (ACP) associated with video, the ACP including authorization rules and cryptographic information associated with an encryption policy; encrypting the video according to the encryption policy; and encoding the encrypted video with the authorization rules and the cryptographic information, which may be used to decrypt and render the encoded video. As an example, an authorized receiver device having credentials and/or capabilities matched to the authorization rules may extract the ACP information from the encrypted video and use it to decrypt and properly render the video. The method may further include visually encoding the encrypted video with at least portions of the authorization rules and the cryptographic information, such that the visually encoded video is renderable as the video by an authorized device, but is renderable as visually unintelligible video by an unauthorized device.

    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： 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： 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.
