Abstract:
1. A computer-implemented method for secure communications on a digital network, comprising: receiving, at a processor, a first packet at a first node of a network; determining, by a processor, whether a subscription exists between the first node and a second node associated with the packet, wherein the subscription comprises a predefined relationship between the first node and the second node; dropping, by the processor, the packet if no subscription exists; performing, by the processor, an authentication of a connection between the first node and the second node if the subscription exists, the authentication comprising: performing, by the processor, a first synchronization of the connection between the first node and the second node if the subscription exists, the first synchronization comprising: encrypting data of the first packet using the first symmetric key; sending, over the network, the first packet to the second node; performing, by the processor, a second synchronization of the connection between the first node and the second node if the subscription exists, the second synchronization comprising:
