Encryption inventor sues Microsoft
-- EDN, July 27, 2007
The inventor of a computer software encryption scheme filed a patent infringement lawsuit against Microsoft, claiming the operating system giant is illegally using that technology in Windows XP and Vista.
The patent for “computer implemented secret object key block cipher encryption and digital signal device” was granted in 2001 to Luciano Paone, then of Safecourier Software in Kings Park, N.Y. Paone is seeking damages, triple damages and an injunction against Microsoft.
The technology in question is based on a 4,096-bit encryption model and a 2,048-bit secret key digital signature process. In addition, the object keys are dynamic, changing throughout the encryption process.
