"Unique" is relatively straight forward. It's something you haven't used before. Unique usually only applies to the individual party, you only need to verify that the IV is unique for your usage with the current key. "Strong" relates to the requirements that your mode of operation has for the IV.

WebSome encryption algorithms require an initialization vector, which is a randomly generated number that is used along with a secret key to encrypt data. This prevents repeated encryption of the same data using the same secret key. The recipient requires this initialization vector to decrypt the message, and hence, is placed in the JWE token. WebMany encryption methods use initialization vectors to provide additional randomization to the data.
