XML has been becoming popular for data
store, document representation and exchange over the
web. Security mechanisms for the protection of XML
document sources and their distribution are essential.
Author-X is a Java based system specifically conceived
for the protection of XML documents. It supports a
range of protection granularity levels and subject credentials,
but also supports push distribution for documents
broadcast. However, the proposed system has
certain disadvantages in terms of both security and dynamic
key management. For example, a sender has to
distribute the secret keys to all correspondent users for
different XML documents. Also, if one of the users
leave or a credential is changed, then the sender has to
re-encrypt all related documents and redistribute the
secret keys to all correspondent users. In this paper,
we present a novel scheme for securing XML documents
and their distribution. Our scheme has several advantages
over Author-X such as (a) one user needs only one
private key, (b) even when the user leaves or a credential
is changed, all the other users will be unaffected
(c) there is no need to establish a secure channel for
key distribution and (d) there is no need for checking
the XML documents for access control policies applied.
These make the security model more efficient and robust
as well as simplifying the programming and the
generation of the encrypted document base.
