WebMay 30, 2015 · The Diffie-Hellman problem for elliptic curves is assumed to be a “hard” problem. It is believed to be as “hard” as the discrete logarithm problem, although no mathematical proofs are available. What we can tell for sure is that it can’t be “harder”, because solving the logarithm problem is a way of solving the Diffie-Hellman ... WebDiffie-Hellman key exchange is a popular cryptographic algorithm that allows Internet protocols to agree on a shared key and negotiate a secure connection. It is fundamental to many protocols including HTTPS, SSH, IPsec, SMTPS, and protocols that rely on TLS.

http://www.ctfiot.com/108979.html WebOct 23, 2013 · Whitfield Diffie and Martin Hellman Modern cryptography is founded on the idea that the key that you use to encrypt your data can be made public while the key that is used to to decrypt your data can be kept private. As such, these systems are known as public key cryptographic systems.
