Question

Quizplus · Accepted Answer

Asymmetric encryption uses two keys, one to encrypt and one to decrypt data.

Answer: B 
 Collision-free means that it is impossible for two different inputs to produce the same output in hashing.

Answer: C 
 Symmetric encryption uses the same key to encrypt and decrypt data.

Answer: D 
 A certificate is an electronic document that verifies the identity of a network user or device.

Answer: E 
 Hashing is the process of converting data into a fixed-size output that cannot be reversed to its original form.

Answer: F 
 A collision is the result of two different inputs producing the same output in hashing.

Answer: G 
 A stream cipher encrypts data one bit or byte at a time, making it suitable for real-time communication.

Answer: H 
 A message digest is a fixed-size output that is generated by hashing a message or data.

Answer: I 
 A block cipher encrypts data in fixed-size blocks, typically 64 or 128 bits at a time.
