Read Abstract +

Quantum computing is coming; and, with it, the security of modern cryptography will be compromised. Technologies such as industrial control systems, banking, and smartphones depend on cryptography to ensure the confidentiality and integrity of operations. Any data sent over the internet relies on cryptography. In some cases, information is so sensitive that if the encryption is broken years in the future the results could be catastrophic. A post-quantum cryptographic solution is required today. Variable World Length is a proposed quantum-proof symmetric cryptography algorithm. It is low-labor, low-latency, and low-power; with a keyspace of 10⁵¹¹ in its simplest form (for comparison, AES-256 is 2²⁵⁶). Variable Word Length performs bit manipulation to send “words” of varied length. Without the key, an attacker would need to brute force all possible combinations. Due to the design of the algorithm, some of these combinations will decrypt real plaintext that was not the encrypted message. Additionally, the keyspace can be increased without an exponential tax on computing resources.
