A targeted discovery between a first device and a second device in a network, in particular, a WHDI network, provides discovery for an identified device or a group of identified devices. The targeted discovery determines an identifier for a second device or a group of devices that the second device belongs to, and sends a device discovery message to the second device using the identifier for the second device when the second device is configured to respond to the device discovery message if the device discovery message includes the identifier for the second device. The first device receives a response to the device discovery message from the second device and can start further communication with the second device.

A method of generating a Personal Identification Number (PIN) between a first device and a second device in a network is provided. The method includes securely receiving information of input choices of the second device and random numbers assigned to the input choices at the first device. At the first device, the PIN is generated from the random numbers, and instructions are provided directing an entry of the input choices on the second device. At the second device, the input choices are entered. The second device is operable to generate the PIN from the input choices and the random numbers if the input choices are entered as instructed.

Personal identification number (PIN) generation between two devices in a network

A method, device and system for authenticating a programmable hardware device, such as a programmable hardware chip, and a command received by the programmable hardware device. A secure processor or other trusted source authenticates the programmable hardware chip by verifying, with the secure processor's own verification key, a random number sent to the programmable hardware chip and encrypted using a verification key embedded within the programmable hardware chip, since the nature of the encryption is such that only the original logic function that includes the verification key can encrypt the data correctly. A command received by the programmable hardware chip is authenticated by verifying that a command authentication token received by the programmable hardware chip is generated using the correct command authentication key and consequently verifying that the command is received from the secure processor, as only the party who has the command authentication key can encrypt the data correctly.

Methods, apparatus and system for authenticating a programmable hardware device and for authenticating commands received in the programmable hardware device from a secure processor

A method for registering a first device with a second device over a wireless network includes receiving a registration request from the first device and sending one or more user input choices to the first device. The user input choices each specify a user input action available though a user interface associated with the second device. A device description describing the second device is sent to the first device in a manner that allows it to be presented to the user by the first device. At least one of the user input actions are sequentially received through the user interface in response to instructions provided to the user by the first device. The first device is registered with the second device if the user input actions received by the second device correctly reflect the instructions provided to the user by the first device.

A domain key is securely distributed from a device in an existing network to a device outside the network. Each device generates the session key on its own using the first random number, the second random number, the Personal Identification Number, and the same key generation function. The device in the existing network sends the domain key encrypted with the session key to the other device.

Secure and efficient domain key distribution for device registration

A method, device and system for securely managing debugging processes within a communication device, such as a set top box or other multimedia processing device. For example, a security processor (SP) within the communication device manages the lifetime (LT) of any access token issued for use in activating debugging privileges within the communication device. The security processor authenticates an issued access token and securely delivers appropriate debug authorization information to the device controller. The security processor uses its secure, internal timer to count down the lifetime and update the remaining lifetime of the issued access token during the processing of each command by the security processor. In addition to securely managing the issuance of the access token and it's remaining lifetime, the updating process reduces any impact on the normal communications within the device. The method overcomes the issue of the communication device not having a secure internal clock.
