SEED Encryption: A Highly Secure Method for Protecting Sensitive Data

Understanding the Advantages, Disadvantages, and Applications of SEED Encryption Algorithm | Karthikeyan Nagaraj

Introduction:

In today’s digital world, securing data has become a crucial aspect of every business or organization. Encryption is a method that is used to protect sensitive data from unauthorized access. SEED encryption is one such method that is widely used for securing data.

What is SEED Encryption?

• SEED encryption is a symmetric key encryption algorithm developed by the Korean Information Security Agency (KISA).
• It is a block cipher encryption method that uses a 128-bit key length and operates on 16-byte blocks of data.
• The SEED encryption algorithm uses a combination of substitution and permutation techniques to scramble the plain text data into cipher text.
• The algorithm uses a Feistel network structure that applies multiple rounds of encryption to produce the final cipher text.

How does SEED Encryption work?

• SEED encryption uses a key schedule to generate round keys that are used in each…
