This is the LOTP (Layered Object Transport Protocol) Security Model document. It describes a generic set of authentication/entryption operations and an API for LOTP services. The security requirements may be met by XML digital signatures, a secure transport security layer (like ssh or https).
This is a living document. While, some effort will be made to maintain the anchors from version to version, it is impossible to guarantee anchor or information persistence over the life of this document.
LOTP is still in experimental stages. It may evolved into an deployed generalized XML protocol or it may be used as a learning experience for designing another protocol.
