Ming crafted a proposal for the OATH Time based OTP algorithm: ------------------------------------------------------------------- 8.4.4.3. TOTP (OATH Time based OTP) Common Name: TOTP Class: OTP URI: http://www.ietf.org/keyprov/pskc#totp Algorithm Definition: http://www.ietf.org/internet-drafts/ draft-mraihi-totp-timebased-00.txt Identifier Definition (this RFC) Registrant Contact: IESG Profile of XML attributes and subelements of the Key entity: For a Key of this algorithm, the <Usage> subelements MUST be present. The "OTP" attribute of the <Usage> MUST be set "true" and it MUST be the only attribute set. The element <ResponseFormat> of the <Usage> MUST be used to indicate the OTP length and the value format. For the Data elements of a key of this algorithm, the following subelements MUST be present in either the Key element itself or an commonly shared KeyProperties element. * Secret * Time * TimeInterval * TimeDrift An example of the Key of this algorithm is as follows. <?xml version="1.0" encoding="UTF-8"?> <KeyContainer Version="1.0" xmlns="urn:ietf:params:xml:ns:keyprov:pskc:1.0"> <Device> <DeviceInfo> <Manufacturer>TokenVendorAcme</Manufacturer> <SerialNo>987654323</SerialNo> </DeviceInfo> <Key KeyAlgorithm="http://www.ietf.org/keyprov/pskc#totp" KeyId="987654323"> <Issuer>Issuer</Issuer> <Usage OTP="true"> <ResponseFormat Length="6" Format="DECIMAL"/> </Usage> <Data> <Secret> <PlainValue> MTIzNDU2Nzg5MDEyMzQ1Njc4OTA= </PlainValue> </Secret> <Time> <PlainValue>0</PlainValue> </Time> <TimeInterval> <PlainValue>30</PlainValue> </TimeInterval> <TimeDrift> <PlainValue>4</PlainValue> </TimeDrift> </Data> </Key> </Device> </KeyContainer> ------------------------------------------------------------------- Ciao Hannes _______________________________________________ KEYPROV mailing list KEYPROV@ietf.org https://www.ietf.org/mailman/listinfo/keyprov
