Current solutions do not address the peculiarities of the security of XML information. Web servers may easily export XML documents, but their protection can typically be defined only at the file system level. Our proposal, presented in [3, 4], introduces an access control model for XML data that exploits the characteristics of XML documents, allowing the definition of access control policies that operate with a fine granularity, permitting the definition of authorizations at the level of the single element/attribute of an XML document.

Architectural and implementation issues of Author- are described, with particular attention to the authorization base and the access control mechanism. An application of Author- to the protection of a real XML source, derived from the Sigmod Record Articles XML Database [7], is presented. As far as we know, Author- is the first tool, we are aware of, supporting XML document protection. In fact, research work in this field has concentrated more on the development of access control models for Web documents [6].

32 DATA AND APPLICATIONS SECURITY 3 We assume that a message transmitted over a channel is guaranteed to be delivered. 4 We assume that all encryptions are strong enough that the receiver of an encrypted message is unable to decrypt the message without the appropriate key. 5 All parties use the same algorithm for encryption as well as for generating cryptographic checksums. 6 Financial institutions are assumed to be trusted. The customer and its financial institution shares a secret key that was established when the customer opened an account with the financial institution.
