An increasing number of business functions from advertising to e-sales and services are being conducted over the Internet. These activities require a secure, reliable and efficient network. The basis of this is the encryption of data as it travels across networks. Students need to appreciate the strengths and weaknesses of the algorithms that are used to secure data. Steganography is often used to hide information in order to defeat an organisation’s defences.
Show an understanding of algorithms and procedures: steganography, encryption, keys, digital signatures and certificates; strengths and weaknesses.
- To appreciate and apply the methodology for steganography and encryption
- Understand the security needs of networks, users and applications.
