US Patent Issued to Circle Internet Group on May 12 for "Post-quantum constant-time key rotation verification" (California Inventor)

ALEXANDRIA, Va., May 12 -- United States Patent no. 12,627,489, issued on May 12, was assigned to Circle Internet Group Inc. (Boston).

"Post-quantum constant-time key rotation verification" was invented by Vipin Singh Sehrawat (Fremont, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Certain aspects of the disclosure provide a method for verifiable key rotation of an encryption key. The method includes generating a ciphertext by encrypting a plaintext with a homomorphic probabilistic encryption scheme based on a first key. The method further includes generating an updating token based on a difference between the homomorphic probabilistic encryption scheme based on a second key and generating a second c...
