Multi-sensor data fusion techniques combine evidences from multiple sensors in order to get more accurate and efficient meaningful information through several process levels that may not be possible from a single sensor alone. One of the most important parts in the data fusion system is the identification fusion, and it can be categorized into physical models, parametric classification and cognitive-based models, and parametric classification technique is usually used in multi-sensor data fusion system by its characteristic. In this paper, we propose a novel heuristic identification fusion method in which we adopt desirable properties from not only parametric classification technique but also cognitive-based models in order to meet the realtime processing requirements.

OTAR system is a highly authentic key management system that has functions with access control. data integrity and data confidentiality, In this paper, we analyze the existing TIA/EIA Over-The-Air-Rekeying key managements protocol. focused to symmetric ciphers. It can be used to understand the technical trend on technologies about TIA/EIA OTAR standardization. This results can be used to evaluate security properties of a remote rekeying, The proposed system contains a highly reliable system synchronization.

This paper describes an implementation method for the people counting system which detects and tracks moving people using a fixed single camera. This system counts the number of moving objects (people) entering the security door. Moreover, the detected objects are tracked by the proposed tracking algorithm before entering the door. The proposed system with In-tel Pentium IV operates at an average rate of 10 frames a second on real world scenes where up to 6 persons come into the view of a vertically mounted camera.

The RFID system is very useful in various fields such as the distribution industry and the management of the material, etc. However, the RFID system suffers from various attacks since it does not have a complete authentication protocol. Therefore, this paper propose the authentication protocol that used key server to resist various attacks including DoS(Denial of Service) attack. For easy implementation, the proposed protocol also uses CRC, RN16 generation function existing in EPCglobal class 1 gen2 protocol. This paper performed security analysis to prove that the proposed protocol is resistant to various attacks. The analytical results showed that the proposed protocol offered a secure RFID system.

Advanced Persistent Threat (APT), aims a specific business or political targets, is rapidly growing due to fast technological advancement in hacking, malicious code, and social engineering techniques. One of the most important characteristics of APT is persistence. Attackers constantly collect information by remaining inside of the targets. Enterprise Security Management (EMS) system can misidentify APT as normal pattern of an access or an entry of a normal user as an attack. In order to analyze this misidentification, a new system development and a research are required. This study suggests the way of forecasting APT and the effective countermeasures against APT attacks by categorizing misidentified data in data-mining through threshold ratings. This proposed technique can improve the detection of future APT attacks by categorizing the data of long-term attack attempts.

E-BLP security model considers the reliability of the processes that are real subjects in systems. This paper deals with the implementation of the E-BLP model for secure embedded systems. Implemented EBSM(E-BLP Based Security Module) consists of three components: identification and authentication, access control and BRC(Dynamic Reliability Check) that checks the process behavior dynamically. Access Control of EBSM ensures unreliable processes not to access the sensitive objects and the DRC detects the buffer overflow attack by normal user. Besides, the performance overhead of the embedded system applying the EBSM is introduced.

The advent of personal healthcare record(PHR) technology has been changing the uses as well as the paradigm of internet services, and emphasizing the importance of services being personalization. But the problem of user's privacy infringement and leaking user's sensitive medical information is increasing with the fusion of PHR technology and healthcare. In this paper, we propose a security labeling scheme for privacy protection in PHR system. In the proposed scheme, PHR data can be labeled also manually based on patient's request or the security labelling rules. The proposed scheme can be used to control access, specify protective measures, and determine additional handling restrictions required by a communications security policy.

This paper proposes a performance analysis model of security servers comprising IPSec accelerators. The proposed model is based on a M/M1 queueing system with traffic load of Poisson distribution. The decoding delay has been defined to cover parameters characterizing hardware of security sorrels. Decoding delay values of a commercial IPSec accelerator are extracted yielding less than 15% differences from measured data. The extracted data are used to simulate the server system with the proposed model. The simulated performance of the cryptographic processor BCM5820 is around 75% of the published claimed level. The performance degradation of 3.125% and 14.28% are observed for 64byte packets and 1024byte packets, respectively.
