• Title: Systematic Solutions to Login and Authentication Security Problems: A Dual-Password Login-Authentication Mechanism
• Authors: Suyun Borjigin,
• Abstract summary: Credential theft and remote attacks are the most serious threats to user authentication mechanisms. We design a dual-password login-authentication mechanism, where a user-selected secret-free login password is converted into an untypable authentication password. The authenticatable functionality of the login password and the typable functionality of the authentication password can be disabled or invalidated to prevent credential theft and remote attacks.

• Abstract: Credential theft and remote attacks are the most serious threats to user authentication mechanisms. The crux of these problems is that we cannot control such behaviors. However, if a password does not contain user secrets, stealing it is useless. If unauthorized inputs are invalidated, remote attacks can be disabled. Thus, credential secrets and account input fields can be controlled. Rather than encrypting passwords, we design a dual-password login-authentication mechanism, where a user-selected secret-free login password is converted into an untypable authentication password. Subsequently, the authenticatable functionality of the login password and the typable functionality of the authentication password can be disabled or invalidated to prevent credential theft and remote attacks. Thus, the usability-security tradeoff and password reuse issues are resolved; local authentication password storage is no longer necessary. More importantly, the password converter acts as an open hashing algorithm, meaning that its intermediate elements can be used to define a truly unique identity for the login process to implement a novel dual-identity authentication scheme. In particular, the system-managed elements are concealed, inaccessible, and independent of any personal information and therefore can be used to define a perfect unforgeable process identifier to identify unauthorized inputs.

• An Alternative to Multi-Factor Authentication with a Triple-Identity Authentication Scheme [0.0]
  A dual-password login-authentication system has two entry points (i.e., username and password fields) to interact with the outside. No identifiers can be defined for the username and password without using any personal information. A triple-identity authentication is established, the key of which is that the readily available user's login name and password are randomly converted into a matrix of meaningless hash elements.

  Tamper-Evident Pairing (TEP) is an improvement of the Push-Button configuration (PBC) standard. TEP relies on the Tamper-Evident Announcement (TEA), which guarantees that an adversary can neither tamper a transmitted message without being detected, nor hide the fact that the message has been sent. This paper provides a comprehensive overview of the TEP protocol, including all information needed to understand how it works.

In this regard, our implementation ROSTAM offers a dashboard that presents all applications the user can access with a single click after a passwordless SSO. The security of web passwords on the credential manager is ensured with a Master Key, rather than a Master Password, so that encrypted passwords can remain secure even if stolen from the server.

  The choice of password composition policy to enforce on a password-protected system represents a critical security decision. In practice, this choice is not usually rigorous or justifiable, with a tendency for system administrators to choose password composition policies based on intuition alone. We propose a novel methodology that draws on password probability distributions constructed from large sets of real-world password data.
