Cryptography enables organizations to achieve several different security goals. In this video, Mike Chapple explains how cryptography achieves the goals of confidentiality, integrity, authentication, and nonrepudiation.
- [Instructor] Security professionals use cryptography … for several different reasons. … We describe those reasons … using the four goals of cryptography. … to preserve confidentiality. … Confidentiality ensures that unauthorized individuals … are not able to gain access to sensitive information. … If Alice and Bob are communicating … with each other using encryption, they want to ensure … that their communication remains private. … And even if a third party, Mal, … intercepts their communication, … she is unable to read the contents. … The second goal of cryptography is integrity. … Integrity protects data against unauthorized modification. … If Alice and Bob are communicating with each other, … they want to make sure that Mal is not able … The third goal of confidentiality is authentication. … Many systems that verify the identity … of users rely upon the use of encryption. … to provide authentication … when we discuss identity and access management. … The final goal of cryptography is nonrepudiation. …
