Security Extension of Border Gateway Protocol BGP-4
Xiong Yong · Dianzi xuebao · 2002
The security weakness of Border Gateway Protocol (BGP 4) is analyzed.Aiming at the weakness,the protocol are extended with some security properties.Digital signature mechanism is used to protect the AS -PATH information.To satisfy the characteristic of distributed routing protocol,a distributed key generation algorithm based on RSA is presented.By integrating these techniques,confidentiality,creditability and integrity of BGP are protected in keeping the packet length with near constant space.
