Abstract
An information handling system for proximity-based authorization for encryption and decryption services may include a local network, a first memory having a private region, and a secure cryptographic module having a communication module stored within the private region. The secure cryptographic module may, when a first timer tick occurs, transmit a first encrypted challenge to a mobile device over the local network using the communication module. The secure cryptographic module may, when a first encrypted response corresponding to the first encrypted challenge is received from the mobile device via the local network using the communication module, decrypt the first encrypted response to a first response, validate the first response based on the secure cryptographic information, and when the first response is validated, enable access to the security services for the mobile device.
