Publicly vs Universal Deniable Encryption

Deniable encryption provides a way for the user to prove the existence of an encrypted file or message as some other value to the adversary instead of the actual value which he/she has encrypted in the ciphertext.

In the deniable encryption, the fake algorithm generates fake randomness so that the same ciphertext maps to a different message but it requires the user to remember the previous randomness used during honest encryption. But Publicly Deniable Encryption does not require the user to remember the previous randomness to obtain the mapping and just has to provide the ciphertext and the message which he/she wishes the adversary to show.

I got the difference between Deniable Encryption and Publicly Deniable Encryption but there is another concept called Universal Deniable Encryption which I did not understand clearly.

What is the change in Universal Deniable Encryption compared to Publicly Deniable Encryption?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
