Securing Information using Cryptography

Cryptography is a process used to keep information secret and safe by transforming it into an unrecognizable form that unwanted and unintended recipients cannot understand. In this course youll explore how cryptography can be used for confidentiality and integrity. Discover when to use symmetric and asymmetric encryption and discover the advantages and disadvantages of both. Explore practical use cases for cryptography and explore how hashing can be used to ensure data integrity. Discover how digital signatures can provide message integrity authenticity and non-repudiation and learn how to implement digital signatures. Discover how to differentiate between rights and permissions and explore access control methods such as discretionary access control mandatory access control and role-based access control. Lastly explore how steganography can be used to hide secret information in or on another object and how digital rights management (DRM) tools can be used to control access to protected data. This course was originally created by Global Knowledge (GK).
