Grid tends to be increasingly demanded in a variety of scientific areas such as Medicine and Bioinformatics. However, Grid would be prevalent among the users in such scientific areas only if their data and privacy can be adequately protected and Grid provides users with adequately scalability and robustness in computation. Thus we view IPv6 and Internet Protocol Security (IPSec) are important technologies for the future global computing. Needless to say, users of Grid want easy, affordable, ubiquitous, broadband access to the Internet.

To satisfy such users’ demands we combine Grid Security Infrastructure (GSI) and IPSec to realize a secure Grid environment that can also balance the trade-off between high-performance and security and have ported Globus (globus2.2.3) to run over native IPv6 network, which is becoming a de facto standard implementation of Grid.

In ccgrid2003, we will show the architecture of our secure Grid environment, performance issues and future directions.
