摘要:
Methods for anonymous authentication and key exchange are presented. In one embodiment, a method includes initiating a two-way mutual authentication between a first entity and a second entity. The first entity remains anonymous to the second entity after performing the authentication. The method also includes establishing a mutually shared session key for use in secure communication between the entities, wherein the initiating and the establishing are in conjunction with direct anonymous attestation (DAA).

Apparatuses for peer-to-peer network setup are presented. In one embodiment, an apparatus comprises a wireless processing unit to communicate with a master device. The wireless processing unit is operable to receive encoded data in a two-dimensional (2D) barcode. The encoded data comprise at least user information associated with the master device including a user identifier, a device identifier, or both. The encoded data further comprise network information including a network identifier, a password, and a profile lifetime value. In one embodiment, the apparatus further comprises a display unit to display at least part of the user information and the network information to a user. The wireless processing unit is operable to initiate a peer-to-peer network setup with the master device based at least on a response from the user.

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.

A computer system includes a service partition, not directly accessible to a user, having a security agent to inspect data entering and exiting the computer system on a virtual private network (VPN) tunnel, and a service partition VPN unit to communicate with a VPN gateway. The computer system also includes a user partition, accessible to a user, having a user partition VPN unit to initiate construction of the VPN tunnel with the VPN gateway. Other embodiments are described and claimed.

Methods for anonymous authentication and key exchange are presented. In one embodiment, a method includes initiating a two-way mutual authentication between a device and a remote entity. The device remains anonymous to the remote entity after performing the authentication. The method also includes establishing a mutually shared session key for use in secure communication, wherein the initiating and the establishing are in conjunction with direct anonymous attestation (DAA).
摘要:
A first message is transmitted over a communication channel to initiate a transaction. The first message contains a random number and a public key of a device. Continuing the transaction, a second message is received. The second message also contains a random number and a public key of a second device. At least one message is received that contains a proof-of-possession of the device's password, along with a credential that is encrypted with a credential key.

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.
