Making Enemies with the NSA - with Martin Hellman (2015 Turing Award)

Turing Award recipient Martin Hellman discusses his career with Oxford Mathematician Dr Tom Crawford, including how he went to war with the NSA over public key cryptography and the Diffie-Hellman Key Exchange.
Recorded at the 2023 Heidelberg Laureate Forum. Find out more about the event at www.heidelberg-laureate-forum...
The story begins in the 1960's and Martin's early work in cryptography at IBM Research. He meets Whitfield Diffie and in 1976 the Diffie-Hellman Key Exchange is created - allowing information to be sent securely online. As the field of cryptography is being developed, Martin faces opposition from the National Security Agency (NSA), but he refuses to back down. He explains his reasons for this, and how it was finally resolved.
In the 1980's Martin switched his focus to the nuclear threat and began working on educating the public on the risk of nuclear annihilation. More information can be found on his website: nuclearrisk.org/
Seven years ago Martin published a book, co-authored with his wife, entitled "A new map for relationships: creating true love at home and peace on the planet". You can download the PDF version for free here: ee.stanford.edu/~hellman/publ...
The ACM A.M. Turing Award is an annual prize given by the Association for Computing Machinery (ACM) to "an individual selected for contributions of a technical nature made to the computing community". The Turing Award is recognized as the "highest distinction in computer science" and "Nobel Prize of Computing". The award is named after Alan Mathison Turing, mathematician and reader in mathematics at the University of Manchester. From 2007 to 2013, the award was accompanied by a prize of US$250,000. Effective 2014, the funding level has been increased to US$1 million, i.e. four times the previous amount
Martin Hellman received the Turing Award in 2015 along with Whitfield Diffie for inventing and promulgating both asymmetric public-key cryptography, including its application to digital signatures, and a practical cryptographic key-exchange method.
