Brian is also a founding member of the Microsoft Cryptography Review Board and consults on security and cryptography architectures, protocols and implementations across the company; previously he was the Director of Security and Cryptography in the Microsoft Extreme Computing Group. He played a leading role in the design of XKMS, the security architecture for .NET and Palladium. He designed and led the development team for the .NET security architecture. He was a security architect on Palladium. His most-referenced work is[2] the .Net Framework. LaMacchia was originally well known for his work at the Massachusetts Institute of Technology establishing the MIT PGP Key Server, the first key centric PKI implementation to see wide-scale use. LaMacchia wrote the first Web interface for a PGP Key Server. He is a submitter of the Frodo post-quantum proposal[3] to the NIST Post-Quantum Cryptography Standardization[4] project.

His leadership has also been recognized by his membership in the Computing Community Consortium (CCC) Council.[5]

He has played a leading role in the design of W3C XMLDsig and XKMS standards. In particular he is an author of versions 1.0, 1.1 and 2.0 XMLDsig. He is a contributor to XKMS. He is coauthor on OASIS standard WS-SECURITY.
