Data Encryption and Compression

This course provides a comprehensive introduction to the essential concepts of data security and compression, equipping learners with the tools to safeguard information and optimize data storage. Beginning with the need for security and encryption, the course explores the significance of protecting sensitive data in a digital age, followed by an overview of types of attacks, including phishing, malware, and cryptographic vulnerabilities. Learners will delve into cryptographic techniques such as RSA (Rivest-Shamir-Adleman) and DSA (Digital Signature Algorithm) to understand secure communication and digital signatures. The course also highlights the need for data compression, discussing its role in reducing storage and transmission costs. Advanced compression techniques, including Huffman coding and Lempel-Ziv algorithms, are covered to illustrate their practical applications in modern data systems. This holistic course is ideal for anyone interested in cybersecurity, cryptography, and data optimization.
