Apply a new product of durations in security

Bùi Vũ Anh, Phan Trung Huy


Whenever we need to conduct a privacy assessment, Zero-knowledge protocol is the one that we can consider. It is used in consulting for privacy and security solutions. In this protocol, there are often two parties: one party has to prove to the other that a statement is true, without revealing anything accepting the veracity. They have an agreement on the way of asking and answering questions. There are two ways to use the protocol: one-time checking and interactive. Some applications require only one-side proof or both-side proof. This paper introduces an algebraic structure of durations and its application to design a Zero-knowledge protocol with high reliability and easy to implement. The complexity for cracking this protocol is O(2^n \times (2n)!) and for implementing is O(n) where n is the length of the key.
