China. Grid Security Requirements (1) • Security requirements for China. Grid platform v Interoperate with existing security infrastructures v Adapt to domain autonomy v Meet the security requirements of various applications v Construct security architecture v Trusted computing for platform legality 13
China. Grid Security Requirements (2) • Security requirements for image processing grid v Basic security requirement (encryption transfer and authentication) v Protect sensitive information produced by remote image processing v Service (including key data, key software, key hardware) authorization requirement - for virtual human and remote sensing image processing grid v User-profile based sensitive record authorization requirement (a decentralized trust management problem) - for medical image diagnosis grid v Security requirement for virtual organization based collaboration processing (more general and abstract level) 14

China. Grid Security Requirements (3) • Security requirements for massive information processing grid v Basic security requirement (encryption transfer and authentication) v Database security operation requirement (to deal with federation of distributed information) for UDMGrid and DPKDD Grid v Data access authorization for different users in cooperative processing 16

Open Issues for China. Grid Security (1) • Technical aspects v Standard policy and assertion presentation v Attribute based authorization and access control v Autonomous authorization delegation v Dynamic and flexible secure virtual organization collaboration v Secure group communication (provide secure group communication mechanism for VO participants) 18
Open Issues for China. Grid Security (2) • Practical aspects v Support Web Service/Grid Service v Adopt standard draft and implement for policy and assertion (SAML, XACML) v Conform to some security drafts, such as WS Security, Liberty Alliance v Adopt ideas from some existing authorization infrastructure, such as PERMIS, AKENTI, CARDEA v Adopt ideas from Single Sign-on (SSO) systems, such as Shibboleth and Source. ID (for the SSO in a virtual organization) v Adopt some ideas from decentralized trust management for Authorization Delegation 19
Open Issues for China. Grid Security (3) • Some aspects need to be further discussed v Security policy negotiation and reconciliation inside the virtual organization (because of security policy conflict in VO) v China. Grid security architecture v Evaluation for China. Grid security technology and policy v Trusted computing mechanism for China. Grid 20
