Secure Authentication Protocol
Secure authentication protocols are essential components of cybersecurity, designed to verify the identity of users, systems, or entities before granting access to resources or services. These protocols ensure that the communication between a user and a system is authentic, preventing unauthorized access and safeguarding sensitive information. Various methods and technologies are employed to achieve secure authentication, each with its unique mechanisms and security features. Here's an overview of some widely used secure authentication protocols and techniques: 1. Password-based Authentication Description: The most basic form of authentication that requires users to input a secret password to gain access. Security Enhancements: To increase security, passwords should be stored in hashed form, and systems should implement account lockout policies and password complexity requirements. 2. Multi-factor Authentication (MFA) Description: MFA requires users to provide two or more verif...
