Whether you find a ready-made deck on SlideShare or build one yourself covering Block Ciphers, RSA, and IPsec, remember that the goal is practical understanding. In the words of Atul Kahate, "Security is not a product, but a process." cryptography and network security atul kahate ppt

Cryptography is the practice and study of techniques for secure communication in the presence of third-party adversaries. It involves the use of algorithms and protocols to protect data confidentiality, integrity, and authenticity. Network security, on the other hand, refers to the practices and technologies designed to protect computer networks from unauthorized access, use, disclosure, disruption, modification, or destruction. It involves the use of algorithms and protocols

Cryptography is the tool; network security protocols are the implementation. Kahate emphasizes the practical application of cryptography in network layers. the fundamental goals remain constant: confidentiality

While technology evolves, the fundamental goals remain constant: confidentiality, integrity, and availability. A robust understanding of these mechanisms is essential for any professional tasked with safeguarding digital assets in a connected world.
