Abstract: In some aspects, the disclosure is directed to methods and systems for using biometric authentication on local or remote devices, without requiring a secure communication channel between the devices. An enrollment operation may be performed on a first device. The enrollment data and user credentials may be encrypted using a cryptography key generated using the biometric information. The encrypted enrollment data may be transferred to the remote device via any available communication channel regardless of its security. On the remote device, the cryptographic key may be regenerated using newly captured biometric data, and the enrollment data and user credentials decrypted. This allows the user to completely eliminate the use of passwords and re-enrollment of biometric authentication on the remote device.

Abstract: Systems and methods are provided for detecting and mitigating a sleep deprivation attack (SDA). A method for detection of the SDA includes one of tracking power consumption rate of a device, incoming request signals received by the device, or an activity duration of one or more physical interfaces of the device. A system for mitigation of the SDA includes the device to be protected from the SDA, a counter to count request signals received by the device from another device, a counter attack circuit to pose one or more security challenges by sending a request message to the other device once a counted number of request signals exceeds a pre-determined number, and a control circuit to terminate connection with the other device if an expected reply based on the request message is not received from the other device within a pre-determined time duration.
