Encrypted key exchange: password-based protocols secure against dictionary attacks

TLDR
A combination of asymmetric (public-key) and symmetric (secret- key) cryptography that allow two parties sharing a common password to exchange confidential and authenticated information over an insecure network is introduced.
Abstract
Classic cryptographic protocols based on user-chosen keys allow an attacker to mount password-guessing attacks. A combination of asymmetric (public-key) and symmetric (secret-key) cryptography that allow two parties sharing a common password to exchange confidential and authenticated information over an insecure network is introduced. In particular, a protocol relying on the counter-intuitive motion of using a secret key to encrypt a public key is presented. Such protocols are secure against active attacks, and have the property that the password is protected against offline dictionary attacks. >

Strong zero-knowledge authentication based on the session keys (sask)

TL;DR: This evolution aims at implementing an authentication protocol with session keys able to verify the users’ identity, to create a secure communication channel, and to supply better cyber-defense against the various types of attacks.

Challenges and architectural approaches for authenticating mobile users

TL;DR: This paper casts an architectural eye at existing work on security and privacy in mobile computing and focuses on authentication as it leads up to access control from two points of view: servicer providers granting access to users, and users granted access to service providers.

Weakness of remote authentication scheme of Chen et al.

TL;DR: This paper presents a three‐factor mobile device‐based remote authentication scheme, which tackled the security risk imposed by the loss of both password and mobile device, but is still vulnerable to the privileged insider attack, the replay attack,The impersonation attack, and the denial of service attack.
