Galois field block cipher IP core as a post-AES alternative
This patent describes a new method for encrypting data in blocks using a mathematical structure called a Galois Extension Field. The approach takes a key generated by a random number generator and plaintext data, lifts both into a higher-dimensional mathematical space, combines them through matrix multiplication, then collapses the result back down into encrypted output. The key innovation is using these algebraic field operations as the core mixing mechanism rather than the substitution boxes and permutations found in standard ciphers like AES. The encryption and decryption are designed to be reversible and mathematically rigorous.
What you could build
A cryptographic library or hardware IP core implementing this cipher, sold or licensed to chip designers, secure communications vendors, or government contractors seeking cipher diversity or post-AES alternatives for embedded and edge devices.
Who in Virginia should care
Northern Virginia defense and intelligence contractors, secure communications firms, and federal IT vendors would have standing interest in novel cipher designs for certification evaluation.
Readiness: Concept
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
