Would a RSA encrypted Diffie-Hellman handshake enable secure communication? I'm encrypting communication from a silverlight client to a php webservice. The silverlight client initiates they key agreement by sending the RSA public key encrypted DH parameters to the webservice. Only the webservice has the private key, so a MITM attack is not
It’s the SSH-specific name for a key exchange algorithm that: * was invented by Whitfield Diffie and Martin Hellman (and some say Ralph Merkle, of Merkle Trees fame) [1] * uses a large (1024-bit) prime number designated SSH group 1 (but known form diffie hellman | RSA Link Feb 20, 2019 Ephemeral Diffie-Hellman with RSA (DHE-RSA) - YouTube

Brief comparison of RSA and diffie-hellman (public key Jan 05, 2016 Which is more secure? RSA, Diffie-Hellmann/DSS Solutions Diffie Hellman is a stronger, thus why PGP uses it. One other interesting note, I guess RSA was patented by MIT, but give exclusive rights to "RSA Security" which screwed a lot of people. However there patent expired in 2000, and PGP still chooses to use DH.
Moreover Diffie-Hellman is symmetric in nature, in the sense that both parties get the same key. RSA is assymetric in nature. RSA keys are always used to sign/encrypt and also during contacting/requesting CA.
Dec 23, 2017 · Diffie-Helman: A way to exchange keys over a public network, it was one of the first ways anyone did this. Two parties exchange a shared key (considered synchronous) that either can use to encrypt Jul 23, 2020 · The Diffie-Hellman protocol is a method for two computer users to generate a shared private key with which they can then exchange information across an insecure channel. Let the users be named Alice and Bob. First, they agree on two prime numbers g and p, where p is large (typically at least 512 bits) and g is a primitive root modulo p.
