Some barriers limit the e-Infrastructure adoption (*) The eResearch2020 report / Some barriers limit the e-Infrastructure adoption

Some introductory concepts and driving considerations Security is based on the Public Key Infrastructure (PKI) of X.509 certificates and the procedures to manage these certificates are unfortunately not straightforward There is a “scientific gap” we have to overcome before to get some benefits in using e-Infrastructures The adoption of robot certificates can reduce these barriers and help non-expert users to experience ICT-based platform technology! CHAIN-REDS School for Application Porting to Science Gateways –

Robot certificates in a nutshell  Robot certificates have been introduced to allow non- expert users to experience e-Infrastructures for research activity; – They are extremely useful, for instance, to automate Grid service monitoring, data processing production, distributed data collection systems; CHAIN-REDS School for Application Porting to Science Gateways –

 Introduction to the “light-weight” crypto library:  Java™ PKCS#11, Bouncy Castle  Java CoG Kits v  VOMS-Admin APIs v.3.0  Apache Tomcat as a Web Container  JAX-RS 1.2 Java APIs using Jersey implementation CHAIN-REDS School for Application Porting to Science Gateways –

The “light-weight” crypto library interface has been designed to provide seamless and secure access to computing e- Infrastructures, based-on gLite MW, using robot certificates The business logic of the library, combines different programming native interfaces and standards such as the: – “cryptoki” Java™ Cryptographic Token Standard Interface (PKCS#11) libraries – Open source BouncyCastle libraries – Java CoG Kits APIs – VOMS-Admin APIs – RESTful technology (JSR 311) The “light-weight” crypto library CHAIN-REDS School for Application Porting to Science Gateways –

List of SW packages adopted The Cryptographic Token Interface Standard (PKCS#11) is a standard introduced by RSA Data Security IncCryptographic Token Interface Standard (PKCS#11)RSA Data Security Inc – It defines native programming interfaces to access cryptographic tokens The Bouncy Castle APIs provide support for creating X.509 certificates (ver.1 and ver.3)Bouncy Castle The Java CoG Kits APIs allow users to provide Globus Toolkit functionality within their code without calling scripts, or in some cases without having Globus installed (v1.8.0)CoG Kits VOMS-Admin APIs (v3.0), developed in the context of the DILIGENT and D4Science projects, were used for interacting the VOMS server and retrieve the list of groups/roles per VO VOMS-AdminDILIGENTD4Science The JAX-RS (Java API for RESTful Web Services) specification presented in JSR 311 defines a standard way to deploy RESTful web servicesJAX-RS CHAIN-REDS School for Application Porting to Science Gateways –

 Deployed on Tomcat Application Server (v7.0.27) Application Server Caching of proxy certificates for each valid requestID – If lifetime(requestID)-12h>0  the cached proxy is sent to the Science Gateway Thread-safe access to the list of smart cards – Evaluated performance of the server using Apache JMeter™ – ~ 6-8 sec. Waiting time for a new proxy – 20 msec. If the proxy is cached CHAIN-REDS School for Application Porting to Science Gateways –

 To reduce security risks, robot certificate are saved on board of the Aladdin eToken USB smart cards The Aladdin eToken smart card can support several certificates: – 4 certificates per each eToken PRO 64KB – PKI Client supports maximum 16 slots! Hardware Tokens A token PIN is prompted every time the user needs to interact with the smart card Costs: – eToken PRO 64KB € 49,00 – eToken PKI Client € 15,90 – eToken Shell € 2,00 CHAIN-REDS School for Application Porting to Science Gateways –
