摘要： Methods in OMA SEC_CF for providing security services to traffic over UDP between a client and a server and the relevant entities are provided. A pre-shared key is pre-shared between the client and the server. A pair of IPSec ESP SAs between the client and the server is established without shared key negotiation, wherein traffic data cryptographic algorithms are determined. Traffic data security keys are derived from the pre-shared key via the determined traffic data cryptographic algorithms. Then, data of the traffic can be provided with security services with the traffic data security keys through use of IPSec ESP.

摘要： The present invention provides a method for shortening signaling delay of ISC session transfer procedure, a network element for controlling ISC session transfer, a network element for anchoring a media path in ISC session transfer and a communication system including at least two terminals and the above two network elements. In the present invention, the SCC AS decides if a media path needs to be anchored in a media anchor point MRF, and if yes, then instructs a MRF to assign respective media endpoints for a local UE and a remote UE and connect the two media endpoints together, so as to divide the session between the local UE and the remote UE into two independent sub-sessions: a session between the local UE and the MRF, and a session between the remote UE and the MRF. For these two sub-sessions, the SIP signaling is terminated and sent out in the SCC AS. Thus, when a local UE or a remote UE triggers handover, only one sub-session needs to be updated/influenced.

摘要： The present invention proposes a method for providing the user with the customized DRM software by the service provider, wherein a universal DRM system is installed and operated in said service provider, and a standard DRM software template is as well stored in said service provider, when the user makes a request for customizing DRM software to the service provider, a customized DRM software is generated from the standard DRM software template and a universal Rights Object of this use is generated; then the customized DRM software and the universal Rights Object are sent to this user. The customized DRM software operates in the user's system containing at least one client and server. A client utilizes the information associated with said one client to decrypt a customized Rights Object which is associated with the protected content and directed to said one client when it is about to access the protected file within the system; and accesses the protected file according to the decrypted customized Rights Object; wherein said customized Rights Object is generated according to the customized Rights Object template of the user's customized DRM software. A new service conception is therefore realized, that is, operators/service providers provide SMEs with “DRM service” to safely manage their proprietary files. Under such service, a layered DRM structure is accomplished, that is, the customized DRM software is protected by the universal DRM system and universal Rights Object operated by the service provider. In addition, the customized DRM software is produced by tailoring the standard DRM software template, it is small and light weight.

摘要： The present invention is directed to promoters of flax conlinin and ω-3 desaturase genes. The promoters guide high levels of the expression exclusively in flax developing seeds. This specific expression pattern concomitant with the biosynthesis of storage lipids and proteins make these promoters particularly useful for seed-specific modification of fatty acid and protein compositions in plant seeds.
