Patent Holders Must License ECC
ECC's intellectual property has been cited as the main factor in slowing or stalling adoption, the researchers said. Currently, Certicom, a subsidiary of BlackBerry, holds more than 100 patents related to elliptic curves and public key cryptography. Researchers at security firm IOActive are urging BlackBerry to freely license implementations of Suite B. Suite B currently supports the Elliptic Curve Diffie-Hellman protocol. The National Security Agency purchased a license that covers all of its intellectual property in a restricted field of use and can be sublicensed to vendors building products that support ECC.
