11. Countermeasure Evaluation and Validation Project (CEVP) Database Requirement Documentation

Author

Abstract

The initial focus of the project by the JSC laboratories will be to develop, test and implement a standardized complement of integrated physiological test (Integrated Testing Regimen, ITR) that will examine both system and intersystem function, and will be used to validate and certify candidate countermeasures. The ITR will consist of medical requirements (MRs) and non-MR core ITR tests, and countermeasure-specific testing. Non-MR and countermeasure-specific test data will be archived in a database specific to the CEVP. Development of a CEVP Database will be critical to documenting the progress of candidate countermeasures. The goal of this work is a fully functional software system that will integrate computer-based data collection and storage with secure, efficient, and practical distribution of that data over the Internet. This system will provide the foundation of a new level of interagency and international cooperation for scientific experimentation and research, providing intramural, international, and extramural collaboration through management and distribution of the CEVP data. The research performed this summer includes the first phase of the project. The first phase of the project is a requirements analysis. This analysis will identify the expected behavior of the system under normal conditions and abnormal conditions; that could affect the system's ability to produce this behavior; and the internal features in the system needed to reduce the risk of unexpected or unwanted behaviors. The second phase of this project have also performed in this summer. The second phase of project is the design of data entry screen and data retrieval screen for a working model of the Ground Data Database. The final report provided the requirements for the CEVP system in a variety of ways, so that both the development team and JSC technical management have a thorough understanding of how the system is expected to behave.

42. Parallel Prediction of Protein-Protein Interactions Using Proximal SVM.

Author

Ślezak, Dominik, JingTao Yao, Peters, James F., Ziarko, Wojciech, Xiaohua Hu, Yoojin Chung, Sang-Young Cho, and Shin, Sung Y.

Abstract

In general, the interactions between proteins are fundamental to a broad area of biological functions. In this paper, we try to predict protein-protein interactions in parallel on a 12-node PC-cluster using domains of a protein. For this, we use a hydrophobicity among protein's amino acid's physicochemical feature and a support vector machine (SVM) among machine learning techniques. According to the experiments, we get approximately 60% average accuracy with 5 trials and we obtained an average speed-up of 5.11 with a 12-node cluster using a proximal SVM. [ABSTRACT FROM AUTHOR]

43. Using Feedback Cycle for Developing an Adjustable Security Design Metric.

Author

Lipo Wang, Yaochu Jin, Shim, Charlie Y., Kim, Jung Y., Shin, Sung Y., and Jiman Hong

Abstract

In this paper, we develop a security design metric that can be used at system design time to build more secure systems. This metric is based on the system-wide approach and adopt a reliability model and scenario testing technique to produce a feedback cycle. [ABSTRACT FROM AUTHOR]

44. Design of a Lightweight TCP/IP Protocol Stack with an Event-Driven Scheduler.

Abstract

The traditional TCP/IP protocol stack is associated with shortcomings related to the context-switching overhead and redundant data copying. The software-based TOE (TCP/ IP Offload Engine), also known as lightweight TCP/IP, was developed to optimize the TCP/IP protocol stack to run on an embedded system. In this paper, we propose the design of a lightweight TCP/IP protocol stack that runs on an event-driven scheduler. An event-driven scheduler is one of the main components of a real-time operating system that provides essential functionalities for an embedded system in network communication. We discuss the problems involved in designing a lightweight TCP/IP with an event-driven scheduler, especially for the issues of TCP transmission and TCP retransmission. We implemented and evaluated the proposed TCP/IP stack on an embedded networking device and verified that the proposed TCP/IP stack is well suited for high-performance networking in embedded systems.

45. An Efficient Secure Deletion Scheme for Flash File Systems.

Abstract

Secure deletion for flash file systems is essential for enhancing the security of embedded systems. Due to the characteristics of flash memory, existing secure deletion schemes cannot be directly adapted to flash file systems. In this paper, we propose an efficient secure deletion scheme for flash file systems. It encrypts a file's data and stores all keys of the file in the same block. This ensures that a single erase operation is sufficient to securely delete a file. Experimental results show that our scheme significantly reduces secure deletion overhead compared with the simple encryption scheme. [ABSTRACT FROM AUTHOR]
