Management of secure element deadlock |
摘要 |
Various embodiments relate to an apparatus and associated method for a contactless front-end (CLF) managing a secure element (SE). When the SE receives a low power, a monitoring circuit in the CLF may monitor a power supplied to the SE. Upon detection of an under-voltage condition, the monitoring circuit may cause a management module in the CLF to react to the detected under-voltage condition with an SE management technique. The management module may enact the SE management technique through a separate communications interface connected to the SE. In some embodiments, the CLF may further comprise a register that maintains an under-voltage flag that is triggered when the monitoring circuit detects an under-voltage condition. The management module may reset the under-voltage flag and may use the triggering of the under-voltage flag one or more times to determine whether to react through use of a SE management technique. |
