Example text

The preprocessing required by the client device creates a weakness in system security, as the individual tag is used for access control only. If the decryption keys are recovered for one consumer, the content would become available in-the-clear and there would be no trace to the illegal distributor. Wireless Network Security. Key management in wireless networks is a more complicated problem because of the mobility of group members [114,115]. When a member joins or leaves a session, the group key needs to change for backward access control and forward access control.

With headquarters in Geneva, Switzerland, it is 1 of the 16 specialized agencies of the United Nations system of organizations. WIPO has currently 179 member states, including the Unites States, China, and the Russian Federation. The legal means of protecting copyrighted digital content can be classified into two categories: 1. 2. National laws (copyright laws and contract laws) International treaties and conventions Two WIPO treaties — the WIPO Copyright Treaty and the WIPO Performances and Phonograms Treaty — obligate the member states to prohibit circumvention of technological measures used by copyright owners to protect their works and to prevent the removal or alteration of copyright management information.

Periodic batch rekeying provides a trade-off between performance improvement and delayed group access control. A new member has to wait longer to join the group, and a leaving member can stay longer with the group. The period of the batch rekeying is, thus, a design parameter that can be adjusted according to security requirements. To accommodate different application needs, three modes of operation are suggested: 1. 2. 3. Periodic batch rekeying. The key server processes both join and leave requests periodically in a batch.
