One-Time Pad Encryption: The Ultimate Guide

Understanding the Key Features, Advantages, and Limitations of One-Time Pad Encryption | Karthikeyan Nagaraj

Introduction:

In the world of cryptography, one-time pad encryption is considered one of the most secure methods of encrypting messages. One-time pad encryption, also known as OTP encryption, uses a random key that is only used once to encrypt plaintext. This article aims to provide a comprehensive guide to one-time pad encryption, including its key features, advantages, and limitations.

Key Features of One-Time Pad Encryption:

• One-time pad encryption is a symmetric key encryption method, meaning the same key is used for both encryption and decryption.
• It uses a random key that is the same length as the plaintext, making it impossible for an attacker to determine the key without prior knowledge.
• One-time pad encryption is theoretically unbreakable, as long as the key remains secret and is only used once.
• It does not require complex mathematical algorithms or large amounts of computing power, making it simple and efficient.
