RFC 3504 IOTP v1 Errata March 2003

1. Introduction

The Internet Open Trading Protocol (IOTP), Version 1.0, is specified
in [RFC 2801, 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 RFC 2801, which was the largest RFC ever issued. These
are listed, with their fix, in this document.

2. DTD Errata

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.

Eastlake Informational [Page 3]

RFC 3504 IOTP v1 Errata March 2003

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.
