Abstract: | The Secure Border Gateway Protocol (S-BGP) is used when two different Autonomous System communicate with each other and upon reception of UPDATE from neighbor Autonomous System. A core layer Router in single Autonomous System called BGP speaker first verifies the receiving update and signs the full path with own digital signature and send it to neighbor AS. In Real scenario so many ASes and Routers communicate to each other. So due to several digital signatures mandates, large storage require in router as well as high processor overhead and more time require for sign generation and verification in S-BGP. In this paper, we propose a new approach that less burden on BGP Speaker for verify and generate number of digital signatures using Autonomous System makes trusted through KDC server. The Central KDC Server will send master certificate to validate autonomous system. In this environment each BGP speaker verify only one sign on each update and verify path only between itself and neighbor router. After verification of UPDATE, each BGP speaker sign full path encrypt routing table with neighbor’s public key, & Neighbor router decrypt routing table with its private key using RSA algorithm. So we show that a new scheme can reduce number of verification to validate path and provide integrity, confidentiality and authentication with less burden on router and less time and memory. |
