IPSec and DNSSEC to Support GRID Application Security

This paper describes a proposal to provide a solution to grid applications specific needs in data transport security. The solution combines different security protocols to secure data transport, integrity and confidentiality. To address the key management part, the solution secures the local DNS server with the DNSSEC extensions, making it become a local certification authority. This design choice solves a dual problem: secret key distribution and scalability of the solution.
