    Abstract: A radio-frequency identification (RFID) device includes an RFID block configured to support RFID communication; a memory having a storage area configured to store a list of pulse width modulation (PWM) parameters; a PWM circuit configured to generate a PWM signal based on a PWM parameter received by the PWM circuit; and a configuration and control (CC) circuit coupled to the RFID block, the memory, and the PWM circuit, where the RFID block, the PWM circuit, the CC circuit, and the memory form part of an RFID tag, where the CC circuit is configured to, in an automatic playback mode: sequentially read the list of PWM parameters from a beginning of the list of PWM parameters; and sequentially send the list of PWM parameters to the PWM circuit.

    Abstract: An electronic component includes a processor and a memory. The electronic component has a secure platform capable of storing at least one dual key pair and a corresponding digital signature. There is also a system including a host machine and an electronic component capable of being operated by the host machine. The electronic component has a processor, a memory, and a secure platform capable of storing at least one dual key pair and a corresponding digital signature. Another aspect describes a method, which includes reading a public key from an electronic component by a host machine, verifying the public key against a stored key in the host machine, digitally signing data using a private key from the electronic component, verifying the signed data against the stored key, and using the electronic component by the host machine only if the signed data and the public key are verified.
