WebSecure Socket Layer (SSL) was the original protocol that was used to provide encryption for HTTP traffic, in the form of HTTPS. There were two publicly released versions of SSL - versions 2 and 3. Both of these have serious cryptographic weaknesses and should no longer be used. WebBeing secure when using attacker chosen, or at least related keys are not primary security properties of a cipher. Typically they're analyzed assuming a randomly chosen secret key. Related key attacks are rather academic. For example AES is still considered secure despite related key attacks against it.

WebJul 13, 2014 · So against a related-key attacker, the effective strength of a block cipher can be no more than half the key length. However, the related-key model is controversial. Putting aside the plausibility of such an attack model, related-key attackers can sometimes be "too powerful". Weba related-key attack, restrictions are necessary on the functions Φi as explained in [9]. Security against related-key attacks is often considered in the design of a block cipher. For example, it was a stated design goal for the AES block ci-pher [23], although it was shown that AES is not secure against related-key attacks [15,16].
