FIELD: information technology.
SUBSTANCE: invention relates to devices and methods for encrypting and transmitting data. In the method, the apparatus comprises a processing unit configured to evenly separate the original data into N first data packets, where N is a positive integer, encrypting the first data packet in the N first data packets, to obtain N packets of encrypted first data, where the number of the first data packet has an N-1 maximum, and encoding, using the fountain code, N packets of encrypted first data to obtain M second data packets, where M is a positive integer, and M > N, and a transmission unit configured to transmit M second data packets received by the processing unit to the receiving side.
EFFECT: technical result is to ensure data security.
