1. Introduction
The Internet Open Trading Protocol (IOTP), Version 1.0, is specified in [RFC2801, 2802, 2803]. It provides a payment system independent framework for Internet commerce oriented to consumer to business transactions. It provides mechanism for different portions of the business function, such as fulfillment or payment handling, to be distributed or outsourced. It does not require a prior relationship between the consumer and business.
Several errors have been noted in the IOTP v1.0 specification, particularly RFC2801, which was the largest RFCever issued. These are listed, with their fix, in this document.
OLD/INCORRECT: <!ELEMENT Attribute ( ANY ) > <!ATTLIST Attribute type NMTOKEN #REQUIRED critical ( true false ) #REQUIRED >
NEW/CORRECT <!ELEMENT Attribute ANY > <!ATTLIST Attribute type NMTOKEN #REQUIRED critical ( true false ) #REQUIRED >
3. Other Errata
3.1 Re: Combining Authentication Transactions with other Transactions
Section 9.1.13. page 234, restarted->continued:
OLD/INCORRECT: if the Authentication transaction is successful, then the original IOTP Transaction is restarted
NEW/CORRECT: if the Authentication transaction is successful, then the original IOTP Transaction is continued
3.2 Type attribute of Element called Attribute
Section 7.19.1, Page 150, insufficient list of signature types:
OLD/INCORRECT: There must be one and only one Attribute Element that contains a Type attribute with a value of IOTP Signature Type and with content set to either: OfferResponse, PaymentResponse, DeliveryResponse, AuthenticationRequest, AuthenticationResponse, PingReq or PingResponse; depending on the type of the signature.
NEW/CORRECT: There must be one and only one Attribute Element that contains a Type attribute with a value of IOTP Signature Type and with content set to either: OfferResponse, PaymentResponse, DeliveryResponse, AuthenticationRequest, AuthenticationResponse, PingReq, PingResponse, AuthenticationStatus, InquiryRequest, or InquiryResponse; depending on the type of the signature.
AND a similar change extending the list of values in Section 12.1, Page 262.
And at Section 6.1.2, Page 82, add the following:
AuthenticationStatus any role
InquiryRequest any role
InquiryResponse any role
4. Security Considerations
The errata listed herein are not particularly security related. Never the less, incorrect implementations due to uncorrected errors in the specification may compromise security.
