    The Korean Access Federation (KAFE) is a union formed to connect user authentications in research and education fields based on identity federation technology.

    Research/educational institutes and related entities are allowed to join the KAFE organized by the Korea Institute of Science and Technology (KISTI). The members of the KAFE are able to use diverse resources and services of other colleges, research institutes and service providers, using their authentication information (ID and password) just as people freely travel around the world with their passport. Identity Federation is a solution in which an web application service grants service access authority based on the results of user authentication performed by the user’s institute and user attribute information unlike the conventional web application service in which user authentication is done based on internal user database.


    • High Energy Physics High Energy Physics High Energy Physics (HEP) represents global collaboration research led by CERN in Switzerland, which owns the world’s largest large hadron collider (LHC). This co-research is joined by about 3,000 people from 38 countries. For connection between tier centers to transmit HEP data in a hierarchical manner, transmission/reception of experimental data and sharing of computational resources, KREONET and GLORIAD resource are essential.

    •  GENOME/BIO GENOME/BIO In a bio-sector, it is critical to quickly transmit and receive globally distributed data and store them into database as knowledge and information. Furthermore, joint research with global institutes and preparation of cyber research space are very important to keep research activities competitive. Data transmission through hyper-speed, high-tech research network, efficient use of computing resources and fast analysis of results would be international competitiveness in a bio-sector.
      03 10
    •  HIGH-TECH MEDICINE HIGH-TECH MEDICINE Current critical issues in a healthcare sector include cultivation of competent medical staff, expansion of the use of medical equipment & resources and telemedicine support on disadvantaged regions. In particular, realtime network connection in a stable fashion is essential in video-centered tele-laparoscopic surgery and medical robots where the transmission and precision of high-resolution image data from medical imaging and pathology are required. In tele-education, competent medical staff in capital regions and others and fair education are required. In terms of personnel exchange, multimedia-sharing technology such as multicast is needed for teleconference.
      04 10
    • WEATHER/CLIMATE WEATHER/CLIMATE For accurate climate prediction and weather forecast under abnormal temperature and rapid climate changes, researchers need more observation data and climate information. For this, they should be fast connected with supercomputer-level massive computational resources. The exchange of climate information and data between Korea Meteorological Administration and international organization through KREONET and GLORIAD bring fast growth and development in climate and meteorological research sectors and improve the accuracy of weather forecast.
