Introduction
What is BGP?
Two essential services
Mapping IP
Source specific paths
Three disastrous consequence
denial-of –service attack
man-in-the-middle attacks
degrades internet routing performance
Problems in Existing system
Lack of security mechanisms, attackers
Spoof
tamper BGP messages
Critical for recipient AS
Validate authenticity
Integrity of update messages
The proposed System
An increase level of security
Reduced computation cost
Implementation
Square Grid for Authentication in BGP
Reducing Signature Block Size Based on Trust
between Ases
Storage-Efficient Key Distribution Protocols
