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, which simply wastes computing resources (such as memory, time, and power) especially in mobile environment. To overcome this limitation, this paper proposes a new approach for compressing and encrypting large XML documents while maintaining queriability over the intermediate document representation. The proposed approach separates document structure from its contents using a variation of the Ctree XML indexing approach (known as the Ctree(+)), then applies context-free lossless encryption and compression techniques over the resulting Ctree(+) intermediate representations. Experiments results show that the proposed approach dramatically enhances queries response times when compared with existing approaches. However, the proposed approach provides lesser compression ratios when compared with context-based compression techniques.

A comparative evaluation of XML repositories Ünal, Özgül; Doğaç, Asuman; Department of Information Systems (2002) Recently XML has established itself as the standard for representing data in scientific and business applications. Starting out as a standard data exchange format over the web, it has become instrumental in all kinds of applications. Almost all standardization efforts on the web today are based on XML. As a consequence, the amount of XML data being stored and processed is large and will be increasing at a very rapid rate. This has caused XML data management to become a focus of research efforts in the datab...
Privacy preserving database external layer construction algorithm via secure decomposition for attribute-based security policies Turan, Uğur; Toroslu, İsmail Hakkı; Kantarcıoğlu, Murat; Department of Computer Engineering (2018) Relational DBMS’scontinue to dominate th emarket an dinference problem on external schema has preserved its importance in terms of data privacy. Especially for the last 10 years, external schema construction for application-speciﬁc database usage has increased its independency from the conceptual schema, as the deﬁnitions and implementations of views and procedures have been optimized. After deﬁning all mathematical background, this work offers an optimized decomposition strategy for the external schema, wh...
Improving the performance of Hadoop/Hive by sharing scan and computation tasks Özal, Serkan; Toroslu, İsmail Hakkı; Doğaç, Asuman; Department of Computer Engineering (2013) MapReduce is a popular model of executing time-consuming analytical queries as a batch of tasks on large scale data. During simultaneous execution of multiple queries, many oppor- tunities can arise for sharing scan and/or computation tasks. Executing common tasks only once can reduce the total execution time of all queries remarkably. Therefore, we propose to use Multiple Query Optimization (MQO) techniques to improve the overall performance of Hadoop Hive, an open source SQL-based distributed warehouse sy...
Design and analysis of hash functions Koçak, Onur; Doğanaksoy, Ali; Department of Cryptography (2009) Hash functions are cryptographic tools that are used in various applications like digital signature, message integrity checking, password storage and random number generation. These cryptographic primitives were, first, constructed using modular arithmetical operations which were popular at that time because of public key cryptography. Later, in 1989, Merkle and Damgard independently proposed an iterative construction method. This method was easy to implement and had a security proof. MD-4 was the first has...
Analysis of recent attacks on SSL/TLS protocols Özden, Duygu; Cenk, Murat; Department of Cryptography (2016) Transport Layer Security(TLS) and its predecessor Secure Socket Layer(SSL) are two important cryptographic, certificate based protocols that satisfy secure communication in a network channel. They are widely used in many areas such as online banking systems, online shopping, e-mailing, military systems or governmental systems. Being at the center of secure communication makes SSL and TLS become the target of attackers and an important field of study for researchers. So many vulnerabilities and attacks towar...
