When you have completed this module, you will have an appreciation of the different types of attacks and under what kinds of situations each might be applicable.
Name:Hash Functions
Description:Continuing on our exploration of the fundamental concept of cryptography, this module will explain the Hash Function, its purpose and application, potential attack vectors, and the importance of hash functions on cryptographic design. Upon completion you will be able to understand the role that hash functions play in cryptography and how cryptographic hash functions differ from other types of hash functions.
Welcome to Introduction to Applied Cryptography. Cryptography is an essential component of cybersecurity. The need to protect sensitive information and ensure the integrity of industrial control processes has placed a premium on cybersecurity skills in today’s information technology market. Demand for cybersecurity jobs is expected to rise 6 million globally by 2019, with a projected shortfall of 1.5 million, according to Symantec, the world’s largest security software vendor. According to Forbes, the cybersecurity market is expected to grow from $75 billion in 2015 to $170 billion by 2020. In this specialization, you will learn basic security issues in computer communications, classical cryptographic algorithms, symmetric-key cryptography, public-key cryptography, authentication, and digital signatures. These topics should prove especially useful to you if you are new to cybersecurity Course 1, Classical Cryptosystems, introduces you to basic concepts and terminology related to cryptography and cryptanalysis. It is recommended that you have a basic knowledge of computer science and basic math skills such as algebra and probability.
