Raytheon BBN Technologies is a wholly owned subsidiary of Raytheon Company (NYSE: RTN).

Ray Tomlinson, a principal engineer with Raytheon BBN Technologies who sent the first network email in 1971 and saved the "@" symbol from probable extinction, was honored last year with the first inductees into the Hall of Fame. Kent developed the world's first Transmission Control Protocol (TCP) end-to-end encryption system and is the author of the "core" Internet Protocol security suite (IPsec) standards, a key security component in major operating systems, firewall products and widely-deployed tunneling protocols. He helped lead the creation of the first email security standard, Privacy Enhanced Mail (PEM), and established the Internet's first Public Key Infrastructure (PKI), which introduced the concepts of certificate policies and certification practice statements. "It is an honor to join the distinguished individuals, including my Raytheon BBN colleague Ray Tomlinson, in the Internet Hall of Fame," said Kent. "Security and privacy have never been more challenging or important than they are today. Security experts must constantly design and implement leading-edge solutions to address an endless barrage of cyber threats." This is the most recent of Kent's many prestigious honors. Among his other honors, he is a Fellow of the Association for Computing Machinery, where he served as a national lecturer; an Internet Society Pioneer Member; a Delta Epsilon Sigma Member; and a National Science Foundation Graduate Fellow in Computer Science.
