TEMPORAL, DELEGABLE AND CHEAP UPDATE ACCESS CONTROL TO PUBLISHED XML DOCUMENTS
Halboob · Journal of Computer Science · 2013
Providing access control for published XML documents on the Web is an important topic.It involves the use of cryptographic techniques, addressing different requirements and, as a result, facing several challenges.Existing solutions still have some weaknesses such as system update cost, number of required secret encryption/decryption keys, size of encrypted document and supporting temporal and delegable access.This study propose a push--based access control policy enforcement mechanism for addressing these issues using a Dynamic Key Management Table (DKMT) and based on Identity Based Encryption (IBE).The proposed mechanism addresses the existing challenges and provides a more acceptable solution.
