2014 journal article

Scalable Distributed Service Integrity Attestation for Software-as-a-Service Clouds

IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS, 25(3), 730–739.

By: J. Du*, D. Dean n, Y. Tan*, X. Gu* & T. Yu n

author keywords: Distributed service integrity attestation; cloud computing; secure distributed data processing
TL;DR: The experimental results show that IntTest can achieve higher attacker pinpointing accuracy than existing approaches, and does not require any special hardware or secure kernel support and imposes little performance impact to the application, which makes it practical for large-scale cloud systems.

Anonymizing bipartite graph data using safe groupings

Cormode, G., Srivastava, D., Yu, T., & Zhang, Q. (2010, February). VLDB JOURNAL, Vol. 19, pp. 115–139.

author keywords: Privacy; Microdata; Graph; Query answering
TL;DR: This work introduces a new family of anonymizations for bipartite graph data, called (k, ℓ)-groupings, which preserve the underlying graph structure perfectly, and instead anonymize the mapping from entities to nodes of the graph. (via Semantic Scholar)

Denial of service attacks and defenses in decentralized trust management

Li, J., Li, N., Wang, X. F., & Yu, T. (2009, April). INTERNATIONAL JOURNAL OF INFORMATION SECURITY, Vol. 8, pp. 89–101.

By: J. Li*, N. Li*, X. Wang* & T. Yu n

author keywords: Trust management; Denial of service; Access control; Trust negotiation; Game theory
TL;DR: This paper studies low-bandwidth Denial-of-Service (DoS) attacks that exploit the existence of trust management systems to deplete server resources, and proposes a defense technique using credential caching, and shows that it is effective in the presence of intelligent attackers.

On the Modeling of Honest Players in Reputation Systems

JOURNAL OF COMPUTER SCIENCE AND TECHNOLOGY, 24(5), 808–819.

By: Q. Zhang*, W. Wei n & T. Yu n

author keywords: reputation; trust; user behavior modeling; collusion-resilient behavior testing
TL;DR: A statistical model is built for the transaction histories of honest players that serves as a profiling tool to identify suspicious entities and is combined with existing trust schemes to ensure that they are applied to entities whose transaction records are consistent with the statistical model.

SecureMR: A Service Integrity Assurance Framework for Map Reduce

25TH ANNUAL COMPUTER SECURITY APPLICATIONS CONFERENCE, pp. 73–82.

By: W. Wei n, J. Du n, T. Yu n & X. Gu n

TL;DR: The proposed SecureMR consists of five security components, which provide a set of practical security mechanisms that not only ensure MapReduce service integrity as well as to prevent replay and Denial of Service (DoS) attacks, but also preserve the simplicity, applicability and scalability of Map Reduce.
