    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: Method and system of secured direct link set-up (DLS) for wireless networks. In accordance with aspects of the method, techniques are disclosed for setting up computationally secure direct links between stations in a wireless network in a manner that is computationally secure. A direct link comprising a new communication session is set up between first and second stations in a wireless local area network (WLAN) hosted by an access point (AP), the direct link comprising a new communication session. The AP generates a unique session key for the new communication session and transfers secured copies of the session key to each of the first and second stations in a manner under which only the first and second stations can obtain the session key. A security mechanism is then implemented on the unsecured direct link to secure the direct link between the first and second stations using a secure session key derived from the session key.
