In today’s digital age, safeguarding our information has become more critical than ever. One of the cornerstone technologies that power data security is cryptography, and understanding it can seem like a daunting task. Fortunately, Coursera’s “Cryptographic Hash and Integrity Protection” course does an excellent job of breaking this complicated subject down into digestible parts.
### Overview of the Course
The course begins with an introduction to cryptographic hash functions, which are integral to modern cryptography. You will learn the fundamental characteristics that differentiate cryptographic hash functions from ordinary ones, and how these functions are structured to meet various security requirements.
One of the standout features of the course is its comprehensive look at how these hash functions are applied. The course delves into the concept of hash chains, which is critical for generating secure one-time passwords using schemes like S/Key, and the fascinating hash trees, particularly Merkle trees, which bolster the security of decentralized digital currencies like Bitcoin.
As the course progresses, you’ll explore message authentication codes (MAC) that protect message integrity and sender authenticity. The nuanced discussion comparing MAC to general encryption techniques and analyzing its resistance to brute-force attacks provides invaluable insights for anyone interested in information security.
The latter part of the course dives into the world of digital signatures, drawing an important parallel between physical and digital authentication. By learning how public-key pairs enforce sender authentication and non-repudiation, participants will come to appreciate the underlying principles that support real-world applications such as RSA signatures and Digital Signature Standard (DSS).
