XML Signatures and Encryption

2016
Many XML uses today need security, particularly in terms of authentication and confidentiality. Consider commercial transactions. It should be clear why purchase orders, payments, delivery receipts, contracts, and the like need authentication. In many cases, particularly when the transaction involves multiple parties, different parts of a message need ...

Exploring queriability of encrypted and compressed XML data

2009 24th International Symposium on Computer and Information Sciences, 2009
When large XML documents are shared, documents compression and encryption become simultaneously important for efficient and secure access. Existing approaches for compressing and encrypting large XML documents provide a non-queriable intermediate document representation, creating a need to decompress and decrypt the whole document before any access ...

Encrypted XML Data Query Processing with Range Query

Applied Mechanics and Materials, 2011
Without decrypting the encrypted blocks, it is difficult to query encrypted XML data. Inspired by Query-Aware decryption scheme, the paper extends the scheme to support range query with value index. Value index is based on order preserving encryption.

A novel model for query over encrypted XML databases

2009 IEEE International Conference on Network Infrastructure and Digital Content, 2009
In recent years, there has been increasing concern about “Database as a Service”(DAS) architectures. Data security is the overriding concern in DAS, and encryption is a natural solution. However, queries over encrypted databases are usually inefficient due to a heap of time on the encryption and decryption.

Developing an efficient query system for encrypted XML documents

Journal of Systems and Software, 2011
XQuery is a query and functional programming language that is designed for querying the data in XML documents. This paper addresses how to efficiently query encrypted XML documents using XQuery, with the key point being how to eliminate redundant decryption so as to accelerate the querying process.

Offline Data Sharing Model Based on Encrypted XML Files

Advanced Materials Research, 2012
A confidentiality system generally needs to operate under a non-network environment. Hence, the adoption of an offline model is necessary to realize data sharing. An offline data-sharing model based on encrypted Extensible Markup Language (XML) files is designed. The combination of various techniques, such as XML mode, XML encryption, and XML signature,

A Retrieve Model of WESU for Encrypted XML Database

2010 2nd International Workshop on Database Technology and Applications, 2010
To resolve the problems of poor security and low retrieve efficiency for XML DAS, a new retrieve model of WESU foe encrypted XML database is presented in this paper. It establishes the value index and structure index in the encrypted XML database, and executes the barrel management algorithm to record the entrance addresses in the value index and ...

Research on Index Scheme of Encrypted XML Data Structure

2020 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery (CyberC), 2020
This paper proposed a B+ tree encrypted XML structure index scheme and further discussed a query model using Dewey coding. In the process of XML document encryption, the XML encrypted data is stored together with the B+ tree index based on the encrypted data on the server-side, to complete the structural index of the encrypted data on the server-side ...
