Steven M. Bellovin is a researcher on computer networking and security who has been a professor in the computer science department at Columbia University since 2005. Previously, Bellovin was a fellow at AT&T Labs Research in Florham Park, New Jersey.

In September 2012, Bellovin was appointed chief technologist for the United States Federal Trade Commission, replacing Edward W. Felten, who returned to Princeton University. He served in this position from September 2012 to August 2013.

In February 2016, Bellovin became the first technology scholar for the Privacy and Civil Liberties Oversight Board.

Career 
Bellovin received a BA degree from Columbia University, and an MS and PhD in computer science from the University of North Carolina at Chapel Hill.

As a graduate student, Bellovin was one of the originators of USENET. He later suggested that Gene Spafford should create the Phage mailing list as a response to the Morris Worm.

Bellovin and Michael Merritt invented the encrypted key exchange password-authenticated key agreement methods. He was also responsible for the discovery that one-time pads were invented in 1882, not 1917, as previously believed.

Bellovin has been active in the IETF. He was a member of the Internet Architecture Board from 1996–2002. Bellovin later was security area codirector, and a member of the Internet Engineering Steering Group (IESG) from 2002–2004.  He identified some key security weaknesses in the Domain Name System; this and other weaknesses eventually led to the development of DNSSEC.

He received 2007 National Computer Systems Security Award by the National Institute of Standards and Technology (NIST) and the National Security Agency (NSA). In 2001, he was elected as a member into the National Academy of Engineering for his contributions to network applications and security.

In 2015, Bellovin was part of a team of proponents that included Matt Blaze, J. Alex Halderman, Nadia Heninger, and Andrea M. Matwyshyn who successfully proposed a security research exemption to Section 1201 of the Digital Millennium Copyright Act.

Bellovin is an active NetBSD user and a NetBSD developer focusing on architectural, operational, and security issues.
