One-time pads encryption hub

Abstract

A system comprising: at least one hardware processor; and a non-transitory computer- readable storage medium having stored thereon program instructions, the program instructions executable by the at least one hardware processor to: receive, by a routing hub in a computer network, from an origin node, a communication intended to a destination node, wherein said communication is encrypted with a one-time pad (OTP) associated with said origin node, apply, by said routing hub, to said communication, a customized OTP configured to simultaneously (i) encrypt said communication with said OTP associated with said destination node, and (ii) decrypt said communication with said OTP associated with said origin node, and deliver said communication to said destination node for decrypting said communication with said OTP associated with said destination node.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Provisional Patent Application No. 62 / 789,636, filed January 8, 2019, the contents of which are incorporated herein by reference in their entirety. Background technique [0003] The present invention relates to the field of data encryption. [0004] In cryptography, a one-time pad (OTP) is an encryption technique that cannot be broken, but requires the use of a one-time pre-shared key that is the same size or longer than the message being sent. In this technique, plaintext is paired with a random key (also known as a one-time pad). Each bit or character of the plaintext is then encrypted by combining it with a corresponding bit or character from the codebook using one of several functions. [0005] If the key is truly random, never reused in whole or in part, and kept secret, it is clearly mathematically impossible to decipher the ciphertext without a copy of the ...

AI Technical Summary

Problems solved by technology

[0006] However, one-time pad cryptography faces several implementation difficulties

First, the secure generation, exchange, and disposal of OTP material, which must be at least as long as the message, is difficult to achieve

Furthermore, the possibility of interception, copying or forensic recovery of the codebook by a third party would completely compromise the security of the method
