Zero knowledge proof system which has received extensive attention since it was proposed is an important branch of cryptography and computational complexity theory. Thereinto, noninteractive zero knowledge proof system contains only one message sent by the prover to the verifier.

Zero-knowledge proofs of knowledge without interaction Abstract: A zero-knowledge proof system of knowledge is a protocol between two parties called the prover and the verifier. The prover wants to convince the verifier that he 'knows' the proof of a given theorem without revealing any additional information.

A Survey of Noninteractive Zero Knowledge Proof System and Its Applications

The zero-knowledge proof of knowledge, first defined by Fiat, Fiege and Shamir, was used by Galil, Haber and Yung as a means of constructing out of a trapdoor function an interactive public-key cryptosystem provably secure against chosen ciphertext attack. We introduce a revised setting which permits the definition of a non-interactive analogue, the non-interactive zero-knowledge proof of knowledge, and show how it may be constructed in that setting from a non-interactive zero-knowledge proof system for N P of the type introduced by Blum, Feldman and Micali.

Our transform outperforms the FS transform protecting the honest verifier from unbounded adversarial provers with no restriction on the number of RO queries.

The popularity of Internet of Vehicles IoV has made people's driving environment more comfortable and convenient. However, with the integration of external networks and the vehicle networks, the vulnerabilities of the Controller Area Network CAN are exposed, allowing attackers to remotely invade vehicle networks through external devices. Based on the remote attack model for vulnerabilities of the in-vehicle CAN, we designed an efficient and safe identity authentication scheme based on Feige-Fiat-Shamir FFS zero-knowledge identification scheme with extremely high soundness. We used the method of zero-one reversal and two-to-one verification to solve the problem that FFS cannot effectively resist guessing attacks. Finally, regarding time overhead, under the same parameters, compared with the existing scheme, the scheme can complete the authentication within 6. Regarding security and soundness, as long as private keys are not cracked, the scheme can resist guessing attacks, which is more secure than the existing scheme.

Provisional Application No. The Government has certain rights in this invention. The proof can be used to convince another that a statement in question belongs to the language, but the zero-knowledge property ensures that the proof will reveal nothing but the truth or falsity of the statement. NIZK proofs are fundamental cryptographic primitives used in many constructions, including CCA2-secure cryptosystems, digital signatures, and various cryptographic protocols. Both papers based their NIZK systems on certain number-theoretic assumptions specifically, the hardness of deciding quadratic residues modulo a composite number. Much research has been devoted to the construction of efficient NIZK proofs, but until now the only known method to do so has been the hidden random bits method wherein the prover has a string of random bits, which are secret to the verifier. By revealing a subset of these bits, and keeping the rest secret, the prover can convince the verifier of the truth of the statement in question.

 Моя просьба покажется вам безумной, - сказала она, заморгав красными глазами, - но не могли бы вы одолжить мне немного денег. Беккер посмотрел на нее в полном недоумении. - Зачем вам деньги? - спросил. Я не собираюсь оплачивать твое пристрастие к наркотикам, если речь идет об. - Я хочу вернуться домой, - сказала блондинка.

Secondly, the attacker in a chosen ciphertext attack is in general entitled to exploit this difficulty in proving knowledge by including the attacked ciphertext among.

 El vuelo a los Estados Unidos. Стоявшая за стойкой симпатичная андалузка посмотрела на него и ответила с извиняющейся улыбкой: - Acaba de salir. Вы на чуть-чуть опоздали.  - Ее слова словно повисли в воздухе. Все-таки он опоздал.

Акулы со скоростными модемами успеют скачать чудовищные объемы секретной информации через открывшееся окно. Из размышлений об этом кошмаре его вывела Соши, подбежавшая к подиуму со свежей распечаткой. - Я кое-что нашла, сэр! - возбужденно сказала .

 Конечно.  - Бринкерхофф рассеянно кивнул, стараясь не смотреть на лиф ее платья. - Когда знаменатель равняется нулю, - объясняла Мидж, - результат уходит в бесконечность. Компьютеры терпеть не могут бесконечности, поэтому выдают девятки.  - Она показала ему другую колонку.

    This paper describes the design and analysis of a new scheme for the authenticated exchange of confidential information in insecure environments within the Internet of Things, which allows a receiver of a message to authenticate the sender and compute a secret key shared with it.
