US 11,082,211 B2 · Systems and methods for secure communication using random cipher pad cryptography

Abstract

Systems and methods with multiple different modes for bidirectional data transfer of messages encrypted with Random Cipher Pads (RCPs) are disclosed. A direct mode is from one single endpoint to another endpoint in a peer-to-peer fashion. A throughput mode may be configured as a communication between endpoints with a cryptographic data server (CDS) managing communications and additional encryption between the endpoints. The CDS further encrypts the messages such that there is a peer-to-peer encryption between the source endpoint and the CDS and a different peer-to-peer encryption between the CDS and destination endpoints. The throughput mode may also be configured as a broadcast communication between a sender and multiple destinations, each with its own different RCP encryption. A router-to-router mode may be thought of as a specific type of peer-to-peer transfer where the peers on each end are routers, servers, Virtual Private Network servers, and gateways rather than user endpoints.

Dependent claims

A computer-implemented method for performing cryptography, comprising:

encrypting a message with a source Random Cypher Key (RCK) to develop an encrypted message, wherein a length of the source RCK is the same as a message length of the message;
determining a destination system for the encrypted message;
maintaining the message in an encrypted state and further encrypting the encrypted message with a combined RCK associated with the destination system to develop a destination encrypted message wherein a length of the combined RCK is the same as the message length;
and
decrypting the destination encrypted message using a destination RCK to restore the message, wherein a length of the destination RCK is the same as the message length.
