SECURE KEY ROTATION FOR AN ISSUER SECURITY DOMAIN OF AN ELECTRONIC DEVICE

摘要

Systems, methods, and computer-readable media for securely rotating keys for an issuer security domain of an electronic device are provided. In one example embodiment, an electronic device may include a communications component that receives encrypted issuer data from a commercial entity subsystem. The electronic device may also include a secure element that, inter alia, decrypts the encrypted issuer data with a first key that is stored in an issuer security domain of the secure element and stores a second key in the issuer security domain based on the decrypted issuer data. Additional embodiments are also provided.
