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
