Why is symmetric encryption also called private key cryptography?
What will be an ideal response?
Symmetric cryptographic algorithms use the same single key to encrypt and decrypt a document. It is therefore essential that the key be kept private (confidential), because if an attacker obtained the key he could read all the encrypted documents. For this reason, symmetric encryption is also called private key cryptography.

Critical Thinking Questions Case 1-1 Roark has just joined a company and in his role as a lead analyst, he will be responsible for determining which systems development method the team uses to create a new application for a major medical supplier. It is a new day at the firm. Roark has been in place for a few weeks, strengthening the communications skills of his employees, getting them to work much better together. Now, the challenge that he faces is not an internal one; it lies with the client, which is increasingly incapable of sticking with decisions. Roark, based on his past experience with other clients like this, is afraid that the client will throw them a curveball and want to make changes late in the game—but that they also will be unwilling to absorb the costs of those changes. For this reason, which method of development will Roark eliminate? A. Structured analysis B. Agile/adaptive methods C. Object-oriented analysis D. Rapid application development
