AUTHENTICATION IN

DISTRIBUTED SYSTEM

THEORY AND PRACTICE

KING SOLOMON YAMBIRE UGR

OVERVIEW

• (^) Authentication is an important aspect of securing distributed systems.

THEORY OF AUTHENTICATION IN DISTRIBUTED

SYSTEMS

• (^) In a distributed system, authentication involves verifying the identity of a user, device, or service that is requesting access to the system.
• (^) This verification process is typically performed using one or more authentication mechanisms, such as passwords, digital certificates, or biometric authentication.

PRACTICE OF AUTHENTICATION IN

DISTRIBUTED SYSTEMS

• (^) In practice, there are many different authentication mechanisms and protocols that can be used in distributed systems. Some common authentication mechanisms include:
• Password-based authentication
• (^) Public Key Infrastructure (PKI)
• (^) Two-factor authentication
• Biometric authentication

PASSWORD-BASED AUTHENTICATION

• (^) ADVANTAGES OF PASSWORD-BASED AUTHENTICATION
• (^) Ease of Use
• (^) Cost-Effective
• (^) DISADVANTAGES OF PASSWORD-BASED AUTHENTICATION
• (^) Security Risks
• (^) User Behavior

PUBLIC KEY INFRASTRUCTURE (PKI)

• (^) PKI is a more advanced authentication mechanism that uses digital certificates and public key cryptography to verify the identity of users and devices.

BIOMETRIC AUTHENTICATION

• (^) This method of authentication is based on the unique biological characteristics of each user such as fingerprints, voice or face recognition, signatures, and eyes
• (^) A scanner or other devices to gather the necessary data about the user
• (^) Software to convert the data into a form that can be compared and stored
• (^) A database that stores information for all authorized users

BIOMETRIC AUTHENTICATION

BIOMETRIC AUTHENTICATION

• (^) Retinal pattern – It is concerned with the detailed structure of the eye
• (^) Signature – Every individual has a unique style of handwriting, and this feature is reflected in the signatures of a person.
• (^) Voice – This method records the frequency pattern of the voice of an individual speaker.

BIOMETRIC AUTHENTICATION

• (^) ADVANTAGES OF BIOMETRIC AUTHENTICATION
• (^) High security
• (^) DISADVANTAGES OF BIOMETRIC AUTHENTICATION
• (^) Privacy concerns

TWO-FACTOR AUTHENTICATION

• (^) ADVANTAGES OF 2FA
• (^) Increased Security
• (^) Improved User Confidence
• (^) DISADVANTAGES OF 2FA
• (^) Complexity
• (^) Cost

MULTI-FACTOR AUTHENTICATION

• (^) Multi-Factor authentication system: – In this type of authentication, more than one factor of authentication is needed. This gives better security to the users.

AUTHENTICATION AND AUTHORIZATION In the authentication process, the identity of users are checked for providing the access to the system While in authorization process, a the person’s or user’s authorities are checked for accessing the resources In the authentication process, users or persons are verified While in this process, users or persons are validated Authentication determines whether the person is user or not. While it determines What permission does the user have? In the authentication process, users or persons are verified While in this process, users or persons are validated
