Crown Sterling Decrypts RSA Asymmetric Public Keys in Live Demonstration

Sponsored by Businesswire

Crown Sterling, an emerging digital cryptography firm, today announced that yesterday at approximately 5:15 p.m. Pacific Time, the company conducted a live demonstration and decrypted two RSA asymmetric public keys at a public gathering at Pelican Hill Resort in Newport Beach, California. Crown Sterling hosted the event with 100+ academics and business professionals in attendance, where Crown Sterling Computer Scientists decrypted two 256-bit asymmetric public keys in approximately 50 seconds from a standard laptop computer. Crown Sterling also announced the consistent decryption of 512-bit asymmetric public key in as little as five hours also using standard computing. The video of the decryption demonstration can be found here:

Crown Sterling also announced the completion of a new white paper to be submitted for peer review, “Novel Geometric Methods for Semiprime Factorization,” co-authored by Robert Edward Grant, Co-Founder and CEO, Crown Sterling, and Talal Ghannam PhD., Physicist and Number Theorist. The paper includes four different geometric and arithmetic methods for public key (semiprime) factorization and one of the methods titled, “The Reciprocal Factoring Method” includes an analysis of reciprocal values of public keys and their embedded private keys (prime factors) found within their period decimal extensions.

“Today’s decryptions demonstrate the vulnerabilities associated with the current encryption paradigm,” said Grant. “We have clearly demonstrated the problem which also extends to larger keys.”

In March of 2019, Grant identified the first Infinite Prime Number prediction pattern where the discovery was published on titled: “Accurate and Infinite Prime Number Prediction from Novel Quasi-Prime Analytical Methodology.” The paper was also co-authored by Ghannam.
