Sécurisation du contrôle d'accès pour des documents XML

摘要: The erosion of trust put in traditional database servers and Database Service Providers the growing interest for different forms selective data dissemination are factors that lead to move access control from clients. Different encryption key schemes have been proposed serve this purpose. By compiling rules into process, all these methods suffer a static way sharing data. With emergence hardware security elements on client devices, more dynamic client-based can be devised. This thesis proposes tamper-resistant XML right controller supporting flexible policies. engine is embedded secure device therefore must cope with specific resources. takes benefit dedicated index quickly converge towards authorized parts – potentially streaming document. Additional mechanisms guarantee input document protected any form tampering replay attacks. Finally, we provide performance measurements show viability our approach smart cards various application contexts.
