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.

Method to prevent cloning of electronic components using public key infrastructure secure hardware device

A method includes providing a power supply package (PSP) that includes a power supply, an RFID tag, and a power switch, where a control terminal of the power switch is coupled to an output terminal of the RFID tag, and load path terminals of the power switch are coupled between an output terminal of the PSP and a first terminal of the power supply, where a control register of the RFID tag is pre-programmed with a first value such that the RFID tag is configured to generate a first control signal that turns off the power switch; receiving, by the RFID tag, a second value for the control register of the RFID tag; and writing, by the RFID tag, the second value to the control register of the RFID tag such that the RFID tag is configured to generate a second control signal that turns on the power switch.

Power supply package with built-in radio frequency identification tag

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.

Audio playback using radio-frequency identification tag

A USB mass storage device includes a memory, USB interface and USB controller. A biometric circuit provides biometric authentication and a secure microcontroller is operatively connected to the biometric circuit and the USB controller and operative in accordance as a trusted platform and having a command set to access security functions and trust authentication of a user using the biometric circuit.

Secure mass storage device

A smart card device includes a card body; and a plurality of card contacts carried by the card body. A smart card chip circuit includes a processor carried by the card body and operably connected to the contacts. At least one memory stores a set of instructions relating to initiating and completing smart card transactions between the smart card device and a smart card host. A biometric circuit is carried by the card body and operable with the processor and used for verifying identity of a user for subsequent smart card device usage. Power is received through a first contact for powering a power circuit for the smart card and a biometric subsystem power circuit receives power through a second contact.

System and method for sensing biometric and non-biometric smart card devices

A system of detecting biometric and non-biometric, standard smart card devices includes a smart card host and smart card device reader, which is operable for receiving an Answer to Reset signal and determining whether the smart card device comprises a biometric or non-biometric, standard smart card device. If a biometric smart card device is detected, the smart card reader is operable for applying power used for standard smart card device operation to a first contact and applying power used by a biometric circuit to a second contact, and if a non-biometric, standard smart card device is detected, applying power only to the first contact.
