Knowledge ProofZME Science
•69% Informative
A zero -knowledge proof demonstrates that a statement or a condition is true without revealing any additional information beyond the validity of the statement itself.
The concept was introduced in the 1980s by Shafi Goldwasser , Silvio Micali , and Charles Rackoff .
It paved the way for modern cryptography and revolutionized proofs in general.
Zero -knowledge proofs are not “proofs” in the strictest sense, because there is some small probability (called a soundness error) that the proof is wrong.
Instead of having proofs where you kind of verify line by line, in your model, proofs are actually an interactive process.
By repeating this test multiple times and always going into the room your friend is in, you demonstrate knowledge of the password without revealing it.
ZKPs are a pivotal leap in how we approach the balance between transparency and privacy, says Wigderson .
The same approach could be used to protect the privacy of people in criminal investigations, for instance, says Kalai .
The researchers’ comments come from press conferences and interviews conducted at the Heidelberg Laureate Forum 2023 .
