Cryptography and Digital Certificates

How does cryptography secure our communication?

Explore the core principles of encryption and cryptography and how they can be applied to enhance cyber security models in real-life settings.

You’ll investigate different encryption methods, digital signatures and certificates, and relevant cyber security laws.

Understand hash functions and encryption methods

Discover how hash functions are used to compress a bulk of message length to a short random-looking, fixed-length message digest.

You’ll also study the two key types of encryption, symmetric encryption, and asymmetric encryption. The course also unpacks the use of digital signatures and certificates as well as other techniques and protocols used for securing communications over a network.

You’ll evaluate different types of attacks on cryptosystems and how to defend against them.

Build your understanding of cyber law

You’ll consider the different types of cybercrime faced by organisations, including cyber-dependent crimes such as hacking and disruption of computer functionality.

You’ll also examine the legal response to cyber crime, including applicable cyber laws and data privacy requirements in the EU.

The course concludes with a look at cloud security issues, studying the emergence of bring your own device policies (BYOD), the emerging trend of employees using their personal devices, and the associated risks.
