HOTP: An HMAC-Based One-Time Password Algorithm

摘要: This document describes an algorithm to generate one-time password values, based on Hashed Message Authentication Code (HMAC). A security analysis of the is presented, and important parameters related secure deployment are discussed. The proposed can be used across a wide range network applications ranging from remote Virtual Private Network (VPN) access, Wi-Fi network logon transaction-oriented Web applications. This work joint effort by OATH (Open AuTHentication) membership to specify that freely distributed technical community. The authors believe common shared will facilitate adoption two-factor authentication Internet by enabling interoperability commercial open-source implementations. memo provides information for Internet community.
