Abstract: Techniques for authenticating a biometric input are disclosed. An example of a biometric authentication system is configured to receive a biometric input, perform a first authentication process on the biometric input with an application processor, such that the first authentication process generates one or more authentication parameters, provide the one or more authentication parameters to a secure processor, perform a second authentication process on the biometric input on the secure processor, such that the second authentication process utilizes the one or more authentication parameters, and output an authentication score based on the second authentication process.

Abstract: Techniques for providing data protection in an integrated circuit are provided. A method according to these techniques includes exchanging messages with an off-chip, non-volatile memory to securely initialize an anti-replay counter (ARC) value in the integrated circuit based on an ARC value stored in the off-chip, non-volatile memory, and maintaining the ARC value stored in the integrated circuit such that the ARC value stored in the integrated circuit remains synchronized with the ARC value stored in the off-chip, non-volatile memory.

Abstract: Techniques for providing data protection in an integrated circuit are provided. An example method according to these techniques includes determining that an unauthorized update has been made to software or firmware associated with the integrated circuit, and corrupting an anti-replay counter (ARC) value, maintained in a one-time programmable memory of the integrated circuit and used by the integrated circuit to protect contents of a non-volatile memory, responsive to determining that the unauthorized update has been made to the software or the firmware.
