Historical remark 11.4.1. Diffie-Hellman controversy.
There is a little controversy over exactly whom to credit for originating the concept of public-key cryptography. Researchers at the British intelligence unit GCHQ published a number of internal papers on methods similar to those in this chapter, and Ralph Merkle previously published a paper introducing the notion. However, the specific mathematics are due to Diffie and Hellman, who were the first to publish in a public venue, so it seems reasonable to keep the traditional name.
