US Patent 7525967 Techniques to control access to logic

Techniques are described herein that can be used to control which packets or other data are able to be processed or otherwise utilize logic of a computing device. For example, a signature may be associated with a packet or other data received from a network. The signature and the packet or other data may be transferred to the computing device. Prior to the computing device deciding whether to allow logic such as hardware or software to use, process, or act using the packet or other data, the computing device may inspect the signature to determine if such signature permits such packet or other data to be used, processed, or acted upon.
