Abstract
The present disclosure relates to a secure transmitting and receiving method that crates a dynamic key on the basis of the features of real-time data, thereby performing authentication operation. A secure transmitting method for real time data according to an embodiment of the present disclosure includes: collecting an n-th datum; compressing the n-th datum; creating and storing an n-th dynamic key in a memory on the basis of a feature extracted in the compressing; creating an n-th security key using an n-m-th dynamic key stored in the memory and transmitting the n-th security key to a server; and transmitting the compressed n-th datum to the server when receiving an authentication success signal from the server.
Claims10
A secure transmitting method for real time data, performed by a plurality of terminals, each of which includes a processor, the secure transmitting method comprising:
- collecting, by each of the plurality of terminals, an n-th datum;
- compressing, by each of the plurality of terminals, the n-th datum;
- creating and storing, by each of the plurality of terminals, an n-th dynamic key in a memory on the basis of a feature extracted in the compressing;
- creating, by each of the plurality of terminals, an n-th security key using an n-m-th dynamic key stored in the memory and transmitting, by each of the plurality of terminals, the n-th security key to a server;
- and
- transmitting, by each of the plurality of terminals, the compressed n-th datum to the server when receiving an authentication success signal from the server.
A secure receiving method for real time data, comprising:
- transmitting a challenge to a terminal in response to an authentication request signal from the terminal;
- receiving an n-th security key from the terminal as response to the challenge;
- creating an n-m-th dynamic key on the basis of a feature extracted from an n-m-th datum received from the terminal;
- creating an n-th authentication key using the n-m-th dynamic key;
- transmitting an authentication success signal to the terminal when the n-th security key and the n-th authentication key are the same;
- and
- receiving an n-th datum from the terminal.
