ABSTRACT:
An apparatus, system and method of secure communications from a human interface device are provided. The apparatus, system, and method receive input data and calculate encrypted data from the input data using a secure credential. In one embodiment the apparatus, system, and method request and receive a single instance credential and calculate the encrypted data using the secure credential and the single instance credential. The encrypted data may be a secure authorization that may be valid for one use. Communication of the encrypted data through networks and communicating devices is secure. The encrypted data may not be decrypted even if intercepted without the secure credential. The apparatus, system, and method enable secure communications from the human interface device.
