Password Authenticated Key Exchange (PAKE) is when two or more parties, solely on the basis of their knowledge of a password, establish a cryptographic key by exchanging messages, so that an unauthorized party (who controls the communication channel but does not have the password) cannot participate in the method and is, where possible, limited by password brute force rates. (The optimal case gives exactly one guess per pass exchange.) Two forms of PAKE are balanced and augmented methods. Internet Key Exchange (IKE) is the protocol that sets up a secure and authenticated communication channel between two parties. IKE uses X.509 PKI certificates for authentication and the Diffie Hellman key exchange protocol to create a common secret key. Password-authenticated key request is a process in which a client receives a static key in a password-based negotiation with a server that knows the data associated with the password. This type of protocol allows the user to obtain the necessary data from the server after authenticated by password. It is important that even after N-1 of all N servers has been compromised, none of the N-1 servers can hide either client server or N server. This makes these schemes useful when a variation of the threshold signature or other threshold algorithm needs to be implemented. AUTHENTICATION, convenient. A certificate from an ordinary official attesting that a registration complies with the law and that the person certifying it is the official designated by law. 2.
The Constitution of the United States, section 4, p. 1, states: „In each State, the trust and recognition of public documents, registrations and judicial proceedings of any other State shall be fully recognized. And Congress can dictate, through general laws, how these acts, recordings, and procedures are to be proven, and their effects. The purpose of authentication is to provide all other evidence of the data set. United States laws provide for a method of authenticating public registers and office documents; These acts are transcribed here. 3. In the act of 26 May 1790 provides that „the act of the legislators of the various states shall be certified by affixing the seal of their respective states: that the registrations and judicial proceedings of the courts of a State be proved or admitted before any other court of the United States, attached by the attestation of the author of the court and the seal of the court, if there is a seal, accompanied by a certificate from the judge, supreme judge or presiding judge, as the certificate is in good shape….
