§ Team-led research effort and provide architecture on Denial of Service Attacks in ATM networks.
§ Researched the applicability of PKI security infrastructure in ATM/MPLS Networks. Recommended Secure Message Exchange with a shared secret key and PKI (X-509 protocols) public key generation and distribution in ATM networks. Solution was based on Internet and ATM security standards: RFC 2510, ATM Security Specification v1.0.
§ Recommended IPsec architecture (RFC 2401 and RFC 2411) as a security mechanism for the ATM control and data plane.
§ Provided high-level architecture for the secure backbone ATM switch.
§ Offered solutions for secure ATM connectivity.
