COMPUTER-IMPLEMENTED METHOD, COMPUTER PROGRAM PRODUCT AND COMMUNICATION SYSTEM FOR DATA TRANSMISSION

A computer-implemented method for data transmission in a communication system is proposed. The method comprising:a) establishing a channel, including an input and an output, between a first unit and a second unit of the communication system, wherein an input IP is assigned to the input and an output IP is assigned to the output,b) receiving, a first IP-packet including first IP-addresses and a payload,c) matching, the first IP-addresses to first database IP-addresses for obtaining a channel-ID,d) generating, a second IP-packet including second IP-addresses, the channel-ID and the payload,e) matching, the channel-ID to a corresponding decryption key and decrypting the payload,f) matching, the second IP-addresses to second database IP-addresses for obtaining a physical destination IP-address, andg) generating, a third IP-packet and transmitting the third IP-packet to a physical destination IP-address.
