1. An encryption retransmission device for providing resiliency against attacks, the encryption retransmission device comprising:
at least one encryption unit configured for:
encrypting an egressing native packet received from at least one device using at least one encryption key to create an encrypted egressing native packet;
adding a connectionless header to the encrypted egressing native packet to form an egressing connectionless datagram;
receiving an ingressing connectionless datagram comprising an ingressing encrypted native packet; and
decrypting the encrypted ingressing native packet using the at least one encryption key;
at least one communication unit communicatively coupled with the at least one encryption unit, wherein the at least one communication unit is paired with at least one first communication unit of at least one first encryption retransmission device, wherein the at least one communication unit is configured for:
receiving the egressing connectionless datagram;
adding a complex header to the egressing connectionless datagram for forming an egressing packet for delivery to the at least one first encryption retransmission device;
receiving an ingressing packet comprising the encrypted ingressing native packet and a complex header from the at least one first encryption retransmission device;
removing the complex header from the ingressing packet; and
adding a connectionless header to the ingressing packet for forming an ingressing connectionless datagram, wherein the ingressing connectionless datagram comprises the encrypted ingressing native packet; and
at least one galvanic isolator electromagnetically coupled with the at least one encryption unit and the at least one communication unit, wherein the at least one galvanic isolator is configured for galvanically isolating the at least one encryption unit and the at least one communication unit.
