Abstract:

In order to sign the vary age value and check its verification. A new secure protection mechanism for open shortest path first (OSPF) routing protocol is proposed through utilizing the sanitizable signature scheme. Enhanced sanitizable signature schemes, combines with the security property of weak transparence on the sanitizable signature algorithm,to protect the routing massage on the OSPF protocol. Security analysis shows, the proposed OSPF protocol can avoid the MaxAge attack and premature MaxAge attack.

Key words: open shortest path first protocol, sanitizable signature, MaxAge attack, Chameleon Hash function
