Encrypting and decrypting information

Abstract

Methods, systems, and devices for encrypting and decrypting data. In one implementation, an encryption method includes inputting plaintext into a recurrent artificial neural network, identifying topological structures in patterns of activity in the recurrent artificial neural network, wherein the patterns of activity are responsive to the input of the plaintext, representing the identified topological structures in a binary sequence of length (L) and implementing a permutation of the set of all binary codewords of length (L). The implemented permutation is a function from the set of binary codewords of length (L) to itself that is injective and surjective.

Description

Background technique [0001] Cryptographic encryption provides secure communications between parties even in the event that a third party (often referred to as an "adversary") intercepts communications. Encrypted communications are encoded such that only authorized recipients have access to the communication. Often, the communication itself is referred to as "plaintext," a term that includes both text messages and other messages. Algorithms for encrypted communications are often referred to as "ciphers," and encrypted communications are referred to as "ciphertext." Decrypting ciphertexts to gain access to encrypted communications is often very difficult, although ciphertexts may be intercepted or otherwise made available to adversaries. [0002] In general, encryption can be classified as "symmetric key" or "public key". In symmetric key encryption, the same key is used to encrypt plaintext and decrypt ciphertext. Since both the sender and receiver must have access to the s...
