Universal Open Strong Authentication for Public Health Grid

Application of GRID technologies as high performance distributed resource sharing to public health shows great promises.  Grid technology allows resources in different geographical domain, different security domain to participate in collaborative data sharing.  The GRID Security Infrastructure uses proxy certificate to address the security issues across difference domains.  Unfortunately, security compromises at any individual site typically results in rapid compromises to the other sites that share the same user population.  Widespread vulnerability can occur given the ability of attackers to harvest the usernames and passwords.  One Time Password (OTP) authentication is an important component in addressing the security issues.  It is recommended that OTP based authentication be added to GRID security infrastructure.  However, commercial OTP technologies are expensive.  And solutions from different vendors are not compatible.  Those issues add further overheads to the building of strong authenticated public health Grid. This presentation proposes the application of Universal Open Strong Authentication to Public Health Grid as a cost effective, standard based, universally compatible OTP security extension to the public health Grid Security Infrastructure.
