Secure wireless communication apparatus

摘要

Aspects of various embodiments are directed to the communication of wireless data. In a particular embodiment, an apparatus includes a master/wireless communication circuit and a slave circuit that carries out a secure function. The master generates session initiation commands, and the slave is responsive to these commands by generating and storing a session ID. In response to the receipt and validation of user-input data, the slave accesses and locally stores the session ID. Upon the initiation of and/or during a wireless communication process, the slave again accesses the session ID and compares the accessed session ID with the locally stored session ID, and facilitates communication based on the comparison (e.g., communication is not permitted if the comparison does not indicate a match).

主权项

1. An apparatus comprising:
a wireless communication circuit configured and arranged to send and receive wireless communications; a first circuit having a timer and configured and arranged to start the timer in response to user input data, and to generate session initiation commands in response to at least one of a status of the timer and a power-based event; and a second circuit having a memory circuit and configured and arranged with
a session identification (ID) circuit configured and arranged to generate and store a session ID in response to each session initiation command, each session ID being different than other session IDs generated by the session ID circuit in response to the session initiation commands, anda communication circuit configured and arranged to
assess validity of the user input data and, in response to the user input data being determined to be valid, access the session ID stored by the session ID circuit, and store the accessed session ID in the memory circuit, andinitiate data communication via the wireless communication circuit for wireless communication to a remote device,access a current version of the session ID stored by the session ID circuit during the data communication and comparing the current version of the session ID with the session ID stored in the memory circuit, and continuing the communication of the data to the wireless communication circuit in response to the current version of the session ID matching the session ID stored in the memory circuit.
