Cites methods from "Encrypted key exchange: password-ba..."
...There have been several methods to solve this problem, such as key exchange protocol using certificates [3] and the authenticated key exchange protocol in which two parties share a secret password (pre-shared password) beforehand [ 4 , 5]. The former has a weakness in that it needs a trusted third certification party....

...Phishing, or server impersonation, occurs when a malicious server convinces a user to reveal sensitive personal information, such as a username and password, to a malicious server instead of the real server....

...Password-authenticated key exchange was first introduced by Bellovin and Merritt in 1992 (Bellovin & Merritt 1992) as the encrypted key exchange (EKE) protocol, in which the client and server shared the plaintext password and exchanged encrypted information to allow them to derive a shared session…...

...And even this risk is minimal if B performs certain checks to guard against easily-solvable choices: that β is indeed prime, that it is large enough (and hence not susceptible to precalculation of tables), that β − 1 have at least one large prime factor (to guard against Pohlig and Hellman’s algorithm[13]), and that α is a primitive root of GF (β)....

...Can such a random odd number less than a known n be distinguished from a valid public key e? Assume that p and q are chosen to be of the form 2p′ + 1 and 2q′ + 1, where p′ and q′ are primes, a choice that is recommended for other reasons [9]....
