Security Enhancement Using Cache Based Reauthentication in WiMAX Based E-Learning System
Algorithm 2
Least Session Based Cache Replacement Algorithm.
Replace | Assumption: all cache blacks are occupied by user session information | Input: , SKS, SID, , T, ASN | Output: Updated cache at ASN | Begin | (1) while cache_block_id != max //check each cache entry | (1.1) If ≥ max or count > 6 //old session | (1.2) Evict the entry //delete the entry from cache | (2) store the user session at ASN | (3) update Timestamp T in AT //update authentication table | End If | End |
