APPARATUS AND METHOD FOR ACCESS CONTROL OF CONTENT IN DISTRIBUTED ENVIRONMENT NETWORK

摘要

An apparatus for generating a key for access control of content in a distributed environment network is provided. The apparatus includes a first key distributor configured to generate first encrypted keys by encrypting a first key corresponding to a key for write authorization using each public key of members having write authorization among members included in an access control list including information of at least one user and distribute the access control list and information about access authorization and the first encrypted keys to the members having write authorization, and a second key distributor configured to generate second encrypted keys by encrypting a second key corresponding to a key for read authorization using the first key using each public key of members having read authorization among members included in the access control list and distribute the access control list and second encrypted keys to the members having read authorization.
