Summary

The system's cryptographic keys must be replaced after a defined period of time, after having produced a certain amount of cipher-text or after its integrity has been weakened, e.g., when an employee with knowledge of a key leaves or when it is believed to have been compromised.

Description

The system's cryptographic keys are essential for maintaining the confidentiality and integrity of transactions and communications. In order to mitigate their decreased effectiveness over time and any possible loss of their integrity, they should be replaced often.
