Abstract - The popular symmetric-key encryption algorithm, the Triple Data Encryption Standard (3DES) is renowned for its strength and security. On the other hand, due to its perfect confidentiality property, One Time Pad (OTP) is an encryption technique that, when used correctly, is theoretically not breakable. The use of 3DES when combined with OTP to improve data encryption security is examined in this study. One must always be cautious so that someone can eavesdrop on our messages. Cryptography is one of the common and widely used techniques to securely send information from one end to the other. The goal of combining 3DES and OTP is to take advantage of both encryption methods. Strong cryptographic security is provided by 3DES through its multiple encryption rounds, while perfect secrecy is achieved by OTP through the use of a randomly generated key that is the same length as the plaintext message. Comparison of the Triple DES algorithm using a one-time pad with other algorithms like RSA, Blowfish, DES, Triple DES, and AES has been done that basically involves assessing various factors such as security strength, computational efficiency, key length, and practicality in different use cases. Each algorithm has its unique strengths and weaknesses, making it essential to evaluate them based on specific security requirements and performance considerations.
