Understanding Cryptography Basics

Cryptography is the backbone of secure communication. It ensures that information remains confidential and unaltered during transmission. Understanding the basics of cryptography is essential for completing your CEN 455 assignment successfully.

The Importance of AES Encryption

AES (Advanced Encryption Standard) is widely used for securing sensitive data. It is crucial to understand how AES works, including its various steps such as SubBytes, ShiftRows, MixColumns, and AddRoundKey. Each step plays a vital role in transforming plaintext into ciphertext.

RSA Encryption: A Key Component

RSA (Rivest-Shamir-Adleman) is another fundamental algorithm in cryptography. It relies on the mathematical properties of prime numbers. Understanding how to calculate n, ϕ(n), and the values of e and d is essential for RSA encryption and decryption.

GCD and Its Applications

The GCD (Greatest Common Divisor) is a concept from number theory that has practical applications in cryptography. Knowing how to compute the GCD using the Euclidean algorithm is crucial for various cryptographic tasks.

The CIA Triad: A Security Framework

The CIA Triad consists of three core principles: Confidentiality, Integrity, and Availability. Understanding how these principles interact and can be compromised is essential for evaluating security measures in your assignment.

Hashing Algorithms: The Role of SHA-8

Hashing is a critical process in securing data. SHA-8 is an example of a hashing algorithm that transforms input data into a fixed-size string of characters. Implementing SHA-8 will enhance your understanding of how hashing works in practice.

By mastering these concepts, you will be well-prepared to tackle your CEN 455 assignment and achieve the grades you desire. Remember, we are here to support you every step of the way. Don't hesitate to reach out for help!
