Many cryptographic applications support a range of different cryptographic algorithms. (a) Which of the applications discussed in this chapter such as cryptography for wireless local area network, cryptography for mobile telecommunications, cryptography for secure payment card transactions, cryptography for video broadcasting cryptography for identity cards, and cryptography for home users support a range of cryptographic algorithms, rather than recommending a fixed encryption algorithm? (b) Discuss the pros and cons of supporting a range of cryptographic algorithms in an application. (c) Why might a relatively weak cryptographic algorithm be included amongst a set of supported cryptographic algorithms? (d) What security issues might arise from including a relatively weak cryptographic algorithm in a set of supported cryptographic algorithms?
