摘要
An authentication method for trusted communication between a first party (A) and a second party (B) is intended to be efficient and secure.;For this purpose, provision is made to combine password-based authentication and certificate-based authentication. For certificate-based authentication, the first party (A) has a static key pair consisting of a private static key and a public static key and a certificate for the public static key issued by a certification body (C). The certification body (C) is assigned a public key which is known by the second party (B). During the certificate-based authentication, the party A calculates a transformation between its own ephemeral key pair from the password-based authentication and its own static key pair from the certificate-based authentication so as to obtain a transformation parameter for carrying out the transformation. The practice of reusing the party's own ephemeral key pair from the password-based authentication in the certificate-based authentication reduces the overall calculation and communication complexity, on the one hand, and links the two protocols, on the other hand, thus ensuring that both protocols are executed by the same party. This increases the security while simultaneously reducing the complexity.;The novel method is suitable for authenticating electronic passports.
