Challenge overview
The Internet and its security: where
computational thinking affects lives
 Resilient: No link is essential. The
A reliable world-wide fast network:
transforming the modern world
 Secure: We can prevent unwanted
Secure and Safe: what would happen if
this Network were to collapse?
 Reliable: We can be certain that every
The Internet:
A network of
communicators
Internet routes around breakages
eavesdropping
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
Aims for the newly published
Computing Curriculum
 Algorithmic thinking
 Can understand and apply fundamental
 Exciting programming tasks
 An understanding of the Internet and
networks in general
principles of computer science
 Can analyse problems in computational
terms, and have experience of writing
programs
 An understanding of security
vulnerabilities and attacks
 Can evaluate and apply IT analytically
Each topic will be studied with a variety
of learning methods: role play, individual
research, programming and maths
challenges, competition etc.,
 Are responsible, competent, confident

to solve problems
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
