Digital Identity & Security – Introduction to PKI

О курсе

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. In this course, you will explore the essential aspects of digital identity and Public Key Infrastructure (PKI) through practical, hands-on learning. You'll gain an in-depth understanding of encryption methods, digital certificates, and secure communication processes. The course provides real-world examples, demonstrating how encryption ensures data security and integrity in online interactions. The course begins with an introduction to PKI, helping you understand how encryption and digital certificates are used to secure data. Throughout the lessons, you'll progress from basic concepts such as symmetric and asymmetric encryption to more advanced topics like certificate authorities, digital signatures, and secure key management. Each video module is paired with practical examples, reinforcing your learning through interactive demonstrations. As you move forward, the course dives deeper into key exchange algorithms, encryption key lengths, and trusted platform modules (TPM). You will also explore tools like HSMs, KMS, and secure enclaves that enhance cryptographic security. The course covers vital topics such as hashing functions, blockchain technology, and SSL/TLS protocols, ensuring you're well-prepared to implement security measures in real-world digital environments. This course is perfect for IT professionals, cybersecurity enthusiasts, and anyone interested in understanding and applying encryption and PKI in the modern digital world. A basic understanding of computing concepts is helpful but not required. The course is beginner-friendly and provides practical insights for enhancing security in digital systems. By the end of the course, you will be able to understand and apply the concepts of digital identity management and PKI. You’ll also gain proficiency in using cryptographic algorithms, secure digital communication techniques, and encryption tools in real-world settings.
