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： A system and method for communication between devices are provided. According to the embodiments of the present disclosure, it is possible to easily authenticate a counterpart device using a one-time key HN(T) for a D2D communication between a first device and a second device, without using a separate secure channel (e.g., secure sockets layer (SSL), transport layer security (TLS), or the like) in an environment where it is difficult to synchronize the first device with the second device without intervention of a server.

摘要： A method of managing a token and a server for performing the same are provided. According to the embodiments of the present disclosure, it is possible to easily authenticate a counterpart device using a one-time key HN(T) for a D2D communication between a first device and a second device, without using a separate secure channel (e.g., secure sockets layer (SSL), transport layer security (TLS), or the like) in an environment where it is difficult to synchronize the first device with the second device without intervention of a server.
