Question

How are IVs used in association with RSA Encryption?

Can someone explain why we use them in this RSA context?

Answer 1

IV is not commonly used in RSA Encryption.

Do you mean:

1. AES Encryption? AES Encryption in some modes, for instance CBC or CFB uses IV (Initial Vector), which is (often) unpredictable value that never repeats for the same key. It is fairly common to generate IV randomly
2. Random padding in RSA Encryption? There are several padding mechanisms defined for RSA Encryption, including e.g. PKCS#1v1.5 padding and OAEP. In RSA encryption, parts of the padding commonly are random, just like some IV's used for symmetric encryption.

In case you are thinking of RSA Encryption padding where IV is actually used, please, provide name of the padding scheme in the question.
