A method for realizing Policy and Charging Control (PCC), includes that: the Policy and Charging Rules Function (PCRF) receives a policy and charging rules request message sent by the Policy and Charging Enforcement Function (PCEF), then compares acquired service flow of user with accumulative used flow, and according to the comparing result, constitutes PCC rule in term of local configured or acquired flow control policy. PCRF of the present invention makes PCC rule decision according to acquired service flow of user, accumulative used flow and flow control policy, and transmits PCC rule to the PCEF to execute. And, PCEF reports to PCRF when the service flow of user arrives at a threshold, PCRF makes PCC rule decision again and transmits to PCEF to execute, consequently the purpose of policy and charging control according to the service flow of user is achieved.

The invention relates to an FPGA-based graph construction acceleration method and system, and the method comprises the steps: sampling the neighborhoods of all vertexes in storage data one by one, and recording the traversal sequence of all vertexes; according to the vertex traversal sequence, dividing all vertexes into a plurality of blocks, and processing according to the granularity of the blocks to at least solve the distance between sampling neighbors of each vertex in each block; updating the neighborhoods of the two vertexes according to the distance between the sampling neighborhoods of each vertex; and after all the vertex blocks are processed, executing the next round of iteration from the step 1 until the precision of the constructed graph meets the precision requirement or the number of iterations is limited. According to the method, the advantages of reconfigurability, low power consumption and high degree of parallelism of the FPGA platform are utilized, and the characteristics ...

The invention relates to an information encryption and trusted deletion method and system. The method at least comprises the following steps: dividing an information field into at least two sensitive levels based on the difference of sensitive degrees; generating encryption keys and key fragments based on a preset threshold value, establishing mapping between a target and the key fragments, encrypting information fields of corresponding sensitive levels based on the encryption keys of different sensitive levels, and deleting original information data; and under the condition that a recovery request is received, recovering the encryption key based on the key fragment and decrypting the encryption key to obtain original information data. Aiming at the problem that the information is difficult to store safely and delete trustingly, multi-party secure key deletion of the encrypted personal information is realized.
