Abstract: An authentication assurance level associated with an entity, for instance a user equipment, may be computed periodically or in response to an event. The authentication assurance level is compared to an authentication threshold. Based on the comparison, it is determined whether a fresh performance of at least one authentication factor needs to be performed. Thus, appropriate authentication factors and functions may be invoked on a periodic basis to maintain a certain authentication assurance level, which is referred to herein as the assurance threshold. The authentication assurance level may change, for instance decay, over time and may be refreshed periodically.
