    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. For large key sizes, the key may be derived using a derivation formula as follows: client_key—MSB=AES128(base_key_1, client_ID),   (1) client_key—LSB=AES128(base_key_2, client_ID+pad), and   (2) client_key=client_key_MSB∥client_key_LSB, where (1) and (2) are executed in parallel. The client key and a client identifier may be used so that end-to-end security may be achieved.

    摘要: Embodiments of the inventions are generally directed to methods, apparatuses, and systems for the dynamic evaluation and delegation of network access control. In an embodiment, a platform includes a switch to control a network connection and an endpoint enforcement engine coupled with the switch. The endpoint enforcement engine may be capable of dynamically switching among a number of network access control modes responsive to an instruction received from the network connection.
