Introduction

Cryptography serves as the cornerstone of cybersecurity and privacy. Classical cryptography primarily addresses the security and privacy of data while it is in transit. In contrast, contemporary cryptography has broadened its application to encompass safeguarding security and privacy in various aspects of digital communication, computation, automation, interaction, transaction, and data preservation.

In this course, learners will acquire a solid grounding in the essentials of symmetric key ciphers, hash functions, and public key ciphers. They will gain a comprehensive understanding of encryption and authentication mechanisms commonly employed in practical settings. Moreover, the course delves into the critical examination of these cryptographic systems, identifying vulnerabilities and potential attack vectors. Consequently, learners will learn how to effectively employ cryptographic tools within sight and proficiency.

Ultimately, this course equips learners with the technical knowledge and skills necessary to appreciate the myriad applications of cryptography within the field of cybersecurity.

 

    This course is part of:

    - Graduate Certificate in Cybersecurity and Digital Trust
     - FlexiMasters in Cybersecurity and Digital Trust

    Learners are encouraged to complete the following core courses before enrolling in the remaining courses:

    1. Foundations of Cybersecurity (1 AU)
    2. Basic Cybersecurity Risk Management (1 AU)
    3. Intermediate Cybersecurity Risk Management (1 AU)

     

    Learners will be exposed to both private and public key cryptography, but without the indepth technical and mathematical details, on how different cryptographic algorithms work and how they can be used for 
    1. protecting data confidentiality 
    2. digital signatures 
    3. maintaining the integrity of data and communication 
    4. considerations of the potential sources of vulnerabilities so that cryptography can be 
    put to effective use. 

    At the end of the course, learners will be able to: 

    • describe how cryptographic algorithms work
    • identify the problems associated with the application of cryptography in real-world scenarios, and
    • explain the operation of various cryptographic mechanisms. 

    Learners will be exposed to both private and public key cryptography, but without the indepth technical and mathematical details, on how different cryptographic algorithms work and how they can be used for
