"Long-term Archive Protocol (LTAP)", Aleksej Jerman-Blazic, Peter Sylvester, Carl Wallace, 13-Jul-09. ( bytes)

This document describes a service operated as a trusted third party to securely archive electronic documents called a long-term archive service (LTA). We describe an architecture framework and a protocol allowing clients to interact with such a service. Bindings to concrete transport and security protocol layers are given.

"Extensible Markup Language Evidence Record Syntax", A. Jerman Blazic, Svetlana Saljic, Tobias Gondrom, 3-Aug-09. ( bytes)

In many scenarios, users must be able to demonstrate the (time) existence, integrity and validity of data including signed data for long or undetermined period of time. This document specifies XML syntax and processing rules for creating evidence for long-term non- repudiation of existence of data. ERS-XML incorporates alternative syntax and processing rules to ASN.1 ERS syntax by using XML language.

"Data Structure for the Security Suitability of Cryptographic Algorithms (DSSC)", Thomas Kunz, Susanne Okunick, Ulrich Pordesch, 29-Jul-09. ( bytes)

Since cryptographic algorithms can become weak over the years, it is necessary to evaluate their security suitability. When signing or verifying data, or when encrypting or decrypting data, these evaluations must be considered. This document specifies a data structure that enables an automated analysis of the security suitability of a given cryptographic algorithm at a given point of time which may be in the past, at the present time or in the future.
