摘要： A method of data encryption according to one embodiment includes generating a structured query language (SQL) syntax that includes manipulation target data and encryption policy identification information in the form of an annotation regarding the manipulation target data, receiving encryption policy information that corresponds to the encryption policy identification information in the form of an annotation from an encryption policy server, and converting the manipulation target data in the SQL syntax into cipher text on the basis of the encryption policy information.

摘要： Disclosed is a data transmitter including: a plurality of write tasks configured to transmit data in parallel to a receiver over a network; and a control task configured to control the plurality of write tasks so that the plurality of write tasks are operated in a fixed transmission rate operation mode or a variable transmission rate operation mode in which a transmission rate varies depending on network conditions. Thus, network bandwidth can be efficiently shared with cross traffic even when a parallel TCP stream is used.
