Challenge overview

The Internet and its security: where computational thinking affects lives

A reliable world-wide fast network: transforming the modern world

Secure and Safe: what would happen if this Network were to collapse?

The Internet:

A network of communicators

Resilient: No link is essential. The Internet routes around breakages

Secure: We can prevent unwanted eavesdropping

Reliable: We can be certain that every message gets through

Flexible: One protocol that can contain any payload package

Scalable−Seamlessly add/remove nodes

It’s the Algorithms that make it Tick

Curriculum links

This STEM challenge will support the new Computing Curriculum

Algorithmic thinking

Exciting programming tasks

An understanding of the Internet and networks in general

An understanding of security vulnerabilities and attacks

Each topic will be studied with a variety of learning methods: role play, individual research, programming and maths challenges, competition etc.,

Aims for the newly published Computing Curriculum

Can understand and apply fundamental principles of computer science

Can analyse problems in computational terms, and have experience of writing programs

Can evaluate and apply IT analytically to solve problems

Are responsible, competent, confident and creative users of ICT

We Tick the Boxes

Examples of activities

Routing past problems (the RIP algorithm):Self-organising networks protect the independence of the Internet

Fix it (Error Correcting Codes): Keeping data coherent across unreliable channels has allowed space exploration, CDs, cheap memory, allowing computational power into almost all human spheres

What’s in a name? (Domain Name Service): Makes the Internet available to people and allows communication between individuals

Public key cryptosystems (RSA):Simple data encryption and signing gives confidence in transactions. This enabled online shopping!

How the Internet speaks (TCP/IP): Overcoming inherent limits of technology with simple techniques and algorithms
