A\r\nsecurity analysis of the algorithm is presented, and important\r\nparameters related to the secure deployment of the algorithm are\r\ndiscussed. The proposed algorithm can be used across a wide range of\r\nnetwork applications ranging from remote Virtual Private Network (VPN)\r\naccess, Wi-Fi network logon to transaction-oriented Web applications.\r\n\r\nThis work is a joint effort by the OATH (Open AuTHentication)\r\nmembership to specify an algorithm that can be freely distributed\r\nto the technical community. The authors believe that a common and\r\nshared algorithm will facilitate adoption of two-factor\r\nauthentication on the Internet by enabling interoperability across\r\ncommercial and open-source implementations. This memo provides information for the Internet community.
