  2. Outline • Introduction to the RESTfull “lightweight”crypto library API: • The Architecture; • SW/HW Requirements; • Success stories. • Investigation of new solutions for the design of a general purpose Grid portal for scientific applications; • GriF: a collaborative tool for grid empowered computational applications.

  3. Introduction to the RESTful “lightweight” crypto library API: • The Architecture; • Software Requirements: • Java™ PKCS#11, Bouncy Castle and Java CoG Kits; • JAX-RS 1.2 Java APIs using Jersey implementation; • VOMS-API v.3.0; • Apache Tomcat 6.0.32 as a Web Container; • Success Stories: • The DECIDE, ViralGrid and EUMEDGrid-Support use cases.

  4. Why a RESTful “lightweight” crypto library ? • REST (Representational State Transfer) is nowadays a de facto standard to access distributed resources in a web-affine manner. • Every resources is uniquely represented by a URI: • Eg.: https://infn-lb-01.ct.pi2s2.it:9000/cANG8Wt2C8PYcL6h8YiLRg • The JAX-RS(Java API for RESTful Web Services) specification presented in JSR 311 defines a standard way to deploy RESTful web services; • Jersey is the open source, JAX-RS (JSR 311) Reference Implementation for building RESTful Web services.

  5. Additional SW/HW Requirements … • The Cryptographic Token Interface Standard (PKCS#11) is a standard introduced by RSA Data Security Inc; • It defines native programming interfaces to cryptographic tokens, (hardware cryptographic accelerators, smart cards, … ); • The Bouncy Castle APIs provide support for creating two kinds of X.509 certificates (ver.1 and ver.3); • CoG Kits allow users to provide Globus Toolkit functionality within their code without calling scripts, or in some cases without having Globus installed; • VOMS-Admin library (ver. 3.0), 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; • eToken PRO smart cards (32/64KB) with the pki-client software (ver. 4.55-34).

  6. The 4-tier architecture of the “lightweight” crypto library Grid Portals / Science Gateways Client Applications Users

  7. Main Features Deployed on Tomcat Application Server (ver. 6.0.32); SafeNet eToken PRO (32/64KB) smart cards; Thread-safe access to the list of smart cards; SSL encryption using a trusted host certificate; Caching of proxy certificates for each valid requestID = serial + vo + fqan If lifetime (requestID) – threshold > 0the proxy cached will be sent to the Science Gateways Evaluated performance of the server using Apache Jmeter: ~ 6-8 s waiting time for a new proxy; 20 ms for a cached proxy.

  8. The working scenario ask for a service eTokenServer get results store long proxy ask for VOMS AC attributes VOMS Server MyProxy Server (*) SSL encryption list/createrequest (*) retrieveserials/proxy (*) execute service get results

  9. Success Stories • The new crypto libraryis currently used by: • The DECIDE Science Gateway (See the DECIDE demonstration at EGI-UF 2011 here); (Abstract [47] – “The DECIDE project Science Gateway”, on Sept. 20th, 14:00 – 14:15, Rhone 3) • The ViralGrid Science Gateway ( web ); • The EUMEDGRID-Support Service Challenge ( web ) and Science Gateway (Abstract[57] – “The EUMEDGRID-Support User Forum”, on Sept. 23rd, 09:00 – 12:30, Rhone 2)
