Public-key cryptographic scheme ideal for short messages and small spaces
MISSISSAUGA, Ontario – (June 7, 2005) –The leading innovator in the mailing industry, Pitney Bowes worked with Certicom to improve methods of authentication for digital postage marks (DPM). Today, Certicom Corp. (TSX: CIC), the authority for strong, efficient cryptography announced that Pitney Bowes has licensed the Nyberg Rueppel (NR) signature scheme, which will give Pitney Bowes more effective protection against fraud without compromising the speed at which DPMs are generated.
Nyberg Rueppel outperforms traditional digital signature schemes because the message itself is encrypted as part of the signature and can be calculated from its signature and the signing public key—all in one step. This approach not only provides tamper-proof authentication, it saves bandwidth and computational power. Nyberg Rueppel is especially valuable for authenticating short messages, such as instant messaging, or for securing messages in an environment with limited space, such as DPMs and smart cards.
Nyberg Rueppel is the foundation for the Elliptic Curve Pintsov-Vanstone signatures (ECPVS) which offers partial message recovery where part of the message is embedded in, and recovered from, the signature. Anticipating global adoption of this technology, Certicom acquired worldwide rights to the Nyberg Rueppel scheme from Entrust. Previously Certicom held rights as an exclusive licensee for North America.
“Digital signatures have always been a valuable security mechanism, especially in e-commerce, and will continue to be so. As more information moves to digital format and threats such as identity theft become more commonplace, sophisticated and flexible signature schemes such as ECNR and ECPVS are needed,” said Dr. Scott Vanstone, Certicom founder and EVP strategic technology. “The addition of ECNR adds further breadth and strength to our intellectual property portfolio and provides another mechanism for securing customers’ valuable data.”
Over the past 20 years, Certicom has built a strong, well-managed intellectual property portfolio that now includes more than 300 individual patents and patents pending worldwide. Certicom’s intellectual property portfolio includes patents covering many key aspects of elliptic curve cryptography, including software optimizations, efficient hardware implementations, methods to enhance the security, and various cryptographic protocols.
