摘要： The present invention relates to a method and a system for performing digital rights management. The idea of the invention is that a master right associated with a content is stored at a first authorized device (211). An authorized device is a device which can be considered trusted and performs actions with contents according to the associated rights. These devices enforce rights that are bound to contents, and perform the security tasks of the DRM system employed. A subright is derived from the master right, which subright controls what type of access a second authorized device (261) is given to the associated content. Finally, the subright is distributed to the second authorized device, given that the second device complies with predetermined distribution criteria associated with the master right. The device distributing the subright authenticates the device which is to receive the subright, ensuring that the second device can be trusted.

摘要： The present invention discloses a method for code channel allocation and related multiuser detection in a wireless communication system. The method for code channel allocation includes: establishing a relation between at least one channel estimation window and a channelization code, wherein the at least one channel estimation window corresponding to the channelization code includes the channel estimation windows corresponding to all the spread spectrum code branches of a node in which the channelization code exists; and performing code channel allocation according to the relation established. In the method for code channel allocation of the invention, there exists a one-to-many relation between the channelization code/channelization code number established and the at least one channel estimation window. Therefore, during the multiuser detection, the channelization code/channelization code number determined via the at least one channel estimation window activated is unique. Thereby, the efficiency of the multiuser detection process may be increased.

摘要： Inhibition of HIV-1 replication by disrupting the processing of the viral Gag capsid (CA) protein (p24) from the CA-spacer peptide 1 (SP1) protein precursor (p25) is disclosed. Amino acid sequences containing a mutation in the Gag p25 protein, with the mutation resulting in a decrease in the inhibition of processing of p25 to p24 by dimethylsuccinyl betulinic acid or dimethylsuccinyl betulin, polynucleotides encoding such mutated sequences and antibodies that selectively bind such mutated sequences are also included. Methods of inhibiting, inhibitory compounds and methods of discovering inhibitory compounds that target proteolytic processing of the HIV Gag protein are included. In one embodiment, such compounds inhibit the interaction of the HIV protease enzyme with Gag by binding to Gag rather than to the protease enzyme. In another embodiment, viruses or recombinant proteins that contain mutations in the region of the Gag proteolytic cleavage site can be used in screening assays to identify compounds that target proteolytic processing.
