WebMay 8, 2012 · Both ciphersuites use RSA to sign the server's emphermeral keys and thus protect the exchange against man-in-the-middle attacks (that is the RSA in the name). Now for the difference. ECDHE-RSA uses Diffie-Hellman on an elliptic curve group while DHE-RSA uses Diffie-Hellman on a modulo-prime group. WebJul 16, 2012 · AES is designed to be more secure than DES: AES offers a larger key size, while ensuring that the only known approach to decrypt a message is for an intruder to try every possible key. AES has a variable key length--the algorithm can specify a 128-bit key (the default), a 192-bit key, or a 256-bit key.

WebThese questions revolve around DH and ECDH vs DHE and ECDHE.Specifically within the context of TLS/SSL. There are three questions in total (and a fourth bonus question). The goal of using Diffie-hellman at all in TLS/SSL is to avoid the case where the contents of the certificate are the sole source for seed value for generating symmetric keys.
