27 Sep Cryptographic algorithms

Your task: You have been asked to give a presentation to the Chief Technology Officer’s (CTO’s) staff for their monthly “brown bag” luncheons. The subject of this session is: Use and Misuse of Encryption.

Background: Cryptographic algorithms provide the underlying tools to most security protocols used to implement encryption in enterprises and critical infrastructures. The choice of which type of algorithm to implement depends on the goal that you are trying to accomplish, e.g. ensuring data privacy or ensuring integrity of software or data. Cryptographic algorithms fall into two main categories: symmetric key and asymmetric key cryptography.

In the first part of your briefing to CTO Staff, please identify and discuss the strengths and weaknesses of

symmetric key cryptography

asymmetric key cryptography

For each type of cryptographic algorithm, you should provide an example of where this type of cryptography would be used within the software and services that the enterprise depends upon and the type of resource to be protected (e.g. passwords stored in hashed format).

In the second part of your briefing, identify and discuss at least three ways in which attackers and/or criminals use encryption and cryptography to further their goals and objectives. These could include using encrypted chat to avoid wiretaps or surveillance or using encryption to deny legitimate users access to data or systems (e.g. ransomware). If countermeasures are available, describe and discuss them.

Format: This week, the format for your deliverable (posting) will be “Talking Points.” Talking points are presented in outline format and contain the content that you would put on slides in a slide deck. Your outline should include 5 to 7 major points (“slide titles”) followed by 3 to 5 supporting points for each. Remember to put enough information into the talking points that your peer reviewers can understand what you intend to cover in each section of your briefing. Remember to introduce the topic at the beginning, present your analysis, and then close your briefing with an appropriate summary. Include a list of sources (3 or more) which attendees could refer to if they wish to fact check your work.
