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 H(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.

Method of managing token and server for performing the same

A method for managing data by an electronic device is provided. The method includes receiving first data inputted from a user, generating second data by encrypting the first data using a public key, generating a query comprising the second data, transmitting the query to a server, receiving third data corresponding to the query from the server, generating fourth data by decrypting the third data using a secret key corresponding to the public key, and outputting the fourth data.

Method and system for communicating homomorphically encrypted data

A buffer amplifier includes an input stage and an output stage. The input stage has input high and low power voltages applied thereon for generating at least one transmission signal from an input signal. The output stage has output high and low power voltages applied thereon for generating an output signal from the at least one transmission signal. A first difference between the output high and low power voltages is less than a second difference between the input high and low power voltages for reducing the dynamic power consumption of the output stage.
