Which of the following is true about cryptographic primitives?
A) each performs several tasks
B) a single primitive makes up an entire cryptographic protocol
C) primitives are usually not the source of security failures
D) a primitive that provides confidentiality usually also provides authentication

Question

Quizplus · Accepted Answer

Cryptographic primitives are typically individual functions used in conjunction with other primitives to create a complete cryptographic protocol. They are designed to perform a specific task, such as encryption, decryption, or hashing. Cryptographic primitives are usually well-studied and peer-reviewed, making them unlikely to be the source of security failures. However, the way in which they are implemented may introduce vulnerabilities. The statement in option A is incorrect because primitives usually perform a single task. The statement in option B is also incorrect because a single primitive is not typically sufficient for an entire cryptographic protocol. The statement in option D is incorrect because some primitives provide confidentiality without authentication.
