Question

When a message is encrypted in two different experiments, the ciphertext should be different. This is an important requirement for encryption. How do AES-128-CBC and RSA encryptions achieve this property?

A) AES-128-CBC uses different IVs and RSA uses random paddings.


B) AES-128-CBC uses different paddings and RSA uses random paddings.


C) AES-128-CBC uses a given padding and RSA uses a random padding.


d) They both use random paddings.

Answer 1

A) AES-128-CBC uses different IVs and RSA uses random paddings.
