A method is provided for collecting diagnostic information in a device having a rich execution environment (REE) and a secure element (SE). The method includes detecting initialization of the device. If it is determined that the initialization of the device was a result of a potential security related event, a communication component of the REE responsible for communicating with the secure element is activated if not already activated. The secure element sends a request to the communication component for diagnostic information related to the security event. The diagnostic information is received in the SE from the communication component and stored in an attack log for storing security events. An attack log is generated in the secure element including the potential security event and the related diagnostic information. The attack log and the related diagnostic information is communicated to a secure server via a secure channel.

Collection of diagnostic information in a device

Embodiments of the present disclosure generally relate to a system, apparatus, and method for providing anti-replay protection of data stored in a non-volatile memory device. Some embodiments describe an anti-replay protection (ARP) device that may protect an external non-volatile memory device from replay attacks.
