Research and Development
1. Information Technology for Rural Community Vitalization Under IT Valley Project Mae Hong Son for Celebrating the Auspicious Occasion of HM the King's 80th Birthday Anniversary:
The Project of Human Resource Development through Utilizing the Information Technology for Rural Community Vitalization Under IT Valley Project Mae Hong Son for Celebrating the Auspicious Occasion of HM the King's 80th Birthday Anniversary is a development research pilot project. This pioneering project utilizes wireless broadband technology (WiMAX) to reduce digital gap between urban and rural area by founding communication infrastructure to remote area. Project's goal is to help increase accessibility of data communication and to support knowledge sharing and development of rural community within Mae Hong Sorn area. The project has been supported by National Telecommunication Commission of Thailand (NTC), allocating a WiMAX license (in the 5GHz frequency) for implementing the system. This helps create an opportunity to promote education in rural areas in Mae Hong Son. Furthermore, the existing infrastructure will be an advantage to boost up development process of other projects under IT Valley Project Mae Hong Son for Celebrating the Auspicious Occasion of HM the King's 80th Birthday Anniversary.

2. Research and Development Project of Wireless Broadband System for National Security
For national security, especially for military, both voice and data communication systems are highly essential for protecting nation security. The communication system can increase the performance of information exchange, data access for every situations, and information superiority. This information is important for decision in critical events. Today wireless broadband technologies have continuously progressed and can support higher speed data rate and longer communication’s range. They can be adapted for use in national security’s activities. The goals of this wireless broadband research and development project are to apply in-house developed wireless broad equipment for national security activities and to reduce importing of equipment from outside country.
3. Research and Development Project of Electronics Instruments for National Security
At the present, a large number of departments have an increasing need for hi-tech electronics instruments for security affairs. We therefore set up a number of projects aimed at responding their needs. For example, we have led the development of jammers which defuse the frequently used improvised explosive devices and provide safe operations in the risk area, resulting in the decreasing activities of terrorists in the southernmost provinces of Thailand. Furthermore, we have developed sensor technology for the detection of attacks to help improve the efficiency of operations.
4. Research and Development Project of Ultra-wideband Technologies for National Security
Ultra-wideband technology has been applied to both high speed wireless communications and security applications. Impulse-based ultra-wideband signal is proposed for research and development in this project. This type of signal possesses a number of unique properties because it is very narrow pulses in time domain imply ultra wide bandwidth in frequency domain. The resulted bandwidth is much wider than typical spread spectrum technique. The ultra-wideband signal are robust to interference, inherited power efficiency due to discontinuous transmission, and less complex in signal generation because it does not need modulation and carrier frequency. From existing research literature, the impulse signal can be adjusted both in shape and form in order to change the bandwidth and its pulse repetition can be changed to adjust the center frequency for different purpose. If very low frequency components are included in the signal, the ultra-wideband signal can penetrate different solid materials such as ground. Moreover, the narrow pulse of ultra-wideband has good time resolution in the order of nano- and pico-second which implies that it can be used to estimate a range or a distance with high accuracy. Thus, it can be used for estimate location of object with high accuracy in radar application. There are several major applications of ultra-wideband signal that can answer the need of the national strategic plan
5. Design and Development of RFID Tags in Ultra-high Frequency Band
The Radio Frequency IDentification (RFID) is a rapidly growing technology and is widely used for identifying data of objects or persons. In a RFID system, data are stored in a tag and read by a reader. In an animal tracking and traceability system, a RFID tag in ultra-high frequency (UHF) band is used for tracking and identifying the poultry cage transferred from farm to slaughterhouse. This is because of the need for the identification of the origin of the animal and data in case of the animal disease outbreak. Most RFID tags sold in the market perform well in free space. However, the performance may decrease when a RFID tag is placed near conductors or high dielectrics and lossy materials. The design and development of RFID tag for a specific application with specific materials can increase the performance of the system. Our RFID tag design will be focused on the antenna design to fit the RFID tag into the selected area and to match the impedance of the antenna to the microchip which results in high performance for the selected application. Furthermore, the development of the RFID tag performance test system is also needed to test the design prototype and also the RFID tag when used in different applications.
6. Research and Development Project of Intrusion Detection System for Wireless Local Area Network
Due to dramatically increase in the adoption of wireless local area network and the growth of new users, the security of this technology has become more important. The conventional case of wired local area network in the enterprise which allows easy intrusion detection of any access to the network at physical layer is no longer applied. In wireless local area network, the wireless signal allows mobility and freedom of access for many users per location which is different from conventional wired network that limits the service connection to only one user per location with access port. This creates an opportunity for intruder of wireless network to be anywhere that the wireless signal can propagate to and allow intruder to steal the access if the wireless network does not have sufficient security built-in.
Intrusion from outsiders can happen via insecure access points of wireless network that did not have proper configuration and sufficient security mechanisms. This usually occurs in the case of rogue access points set up by ordinary workers for their own convenient without security consideration. Currently, National Science and Technology Development Agency (NSTDA) does not deployed intrusion detection and prevent unauthorized setting up of access points which is a serious threat which can happen to large organizations. The goal of this project is to develop a system that has a capability to detect an installation of access point in the local area network and proposes a format of data collection in the database for future research and development.
7. Research and Development Project of Computer Security in Healthcare
We are involved in the project of Smart Heath, aiming to standardize Thai healthcare information. We found that at the present departments under the Ministry of Public Health send medical data through computer networks to the Ministry’s centralized system which aims to process all the data collected for other national purposes. As such data include patient data, treatment data, and other related statistical data, they could be indicated as highly important and confidential. Transmitting these data through unsecured Internet connections is highly risky to be attacked and the confidential data could be easily accessed. We therefore conduct this research to apply security technology for the healthcare system in Thailand.
8. Advisor of Communication & Information Systems for the Control of Avian Influenza (CISCAI):
As of 28 May 2008, there were 383 confirmed human cases and 241 reported deaths due to Avian Influenza (AI) around the world. Out of these, 274 cases and 186 deaths were found in the Association of Southeast Asian Nations (ASEAN) Member Countries, making the Southeast Asia region a “hotspot”; for AI infections and fatalities and therefore a reason for global health concern.
To successfully combat AI is like fighting fire, i.e. catch or detect them early on, and then try to nip them in the bud by timely and swift response. For this to occur, having a robust surveillance system with adequate capacity to effectively monitor and analyze the situation, both in the poultry as well as human sectors, in as close to real time as possible and covering a sufficiently extensive area, is essential. Moreover, it is equally important to be able to present the gathered inter-sectoral information in a form which is readily understood by the concerned officials who have to make quick and well-informed decisions or take immediate actions in a relatively short period of time.
ASEAN Foundation and National Electronics and Computer Technology Center has signed an agreement of cooperation on Aug 20, 2008 to have National Security Technology and Innovation R&D section acting as technical support advisor for the CISCAI project
9. Thai Computer Emergency Response Team (ThaiCERT)
Thai Computer Emergency Response Team (ThaiCERT) project has its main mission in promoting safe and secure computer and network usage for the country. It monitors news and incidents around the world to alert and warn general public in Thailand. Our public service includes:
Response to threats and incidents in computer systems and networks for government entities and any other entities per request
Publish information in forms of digital articles, advisories, and alerts for computer security to general public. Raise awareness and understanding about computer and information security
ThaiCERT is currently an active member of Asia Pacific Computer Emergency Response Team (APCERT) which is formed as a network of specialists for increasing coordination and collaboration among CERTs in Asia Pacific region to counteract the growing threats in computer systems and networks. Moreover, ThaiCERT is also a member of Forum of Incident Response and Security Team (FIRST) which is a coordination network of CERT at the global level.
10. Secretary of the Subcommittee on Security under the Committee on Electronics Transaction
We act as a secretary and subcommittee of the Subcommittee on Security. We have main missions in studying, researching, and giving suggestions on standards or policies related to security in order to raise security awareness of the use of computer and network system. For example, we developed the national security standard based on ISO/IEC 27001:2005 and ISO/IEC 17799:2005. Our responsibilities also include raising security awareness of private sectors and providing critical information about computer security for general public.
11. Operation and maintenance service project for wireless local area network in Thailand Science Park under National Science and Technology Development Agency (NSTDA):
WIS under the national electronics and computer technology center (NECTEC) is entrusted by NSTDA to design, install, and manage secure wireless local area network using our own software tool on the campus of Thailand Science Park. This network is aimed to expand the networking capabilities for every department within the Thailand Science Park. WIS installed and opened our services of wireless local area network for NSTDA on February 1st, 2007. WIS recognized the important of maintaining the wireless local area network in order to provide efficient and secure service to every user within the Thailand Science Park. We propose this operation and management project to maintain business continuity and secure service.
