He also relates his subsequent work in cryptography with Steve Pohlig (the Pohlig-Hellman system) and others. Hellman addresses his involvement with and the broader context of the debate about the federal government’s cryptography policy—regarding to the National Security Agency’s (NSA) early efforts to contain and discourage academic work in the field, the Department of Commerce’s encryption export restrictions (under the International Traffic of Arms Regulation, or ITAR), and key escrow (the so-called Clipper chip). He also touches on the commercialization of cryptography with RSA Data Security and VeriSign, as well as indicates some important individuals in academe and industry who have not received proper credit for their accomplishments in the field of cryptography.en-USComputer historyBeyond War.Cylink.Data encryption (Computer science)Diffie, Whitfield.Great Britain.
