ARX Releases Yubikey-Ready CoSign Digital Signature Solution

SAN FRANCISCO and PALO ALTO, Calif., Feb. 21, 2012 – ARX, Inc., a global provider of cost-efficient digital signature solutions, and Yubico, the leading provider of simple, open online identity protection, extended ARX CoSign® to support YubiKey authentication tokens, making it easy to protect digital signature functionality with secure and easy to use two-factor authentication.

Adding digital signature function to Yubico’s authentication device enhances cloud security. By pairing ARX’s CoSign® digital signature solution and Yubico’s YubiKey® authentication solution, businesses of all sizes gain the proper controls over user authentication and digital signatures in cloud computing environments, enhancing the security of online transactions, and business-critical data and applications in the cloud.

“Companies that conduct business in the cloud can examine verified, standard digital signatures with more certainty because CoSign-signed documents carry proper evidence and integrity represented by compliant NIST FIPS PUB 186 signatures,” said Stina Ehrensvard, CEO, Yubico. “This also makes it easier for organizations to accelerate the speed of business while minimizing transaction-related misunderstandings, creating new opportunities for companies to conduct business online with both identity and data integrity.”

Manufactured in Sweden, the YubiKey is a hardware authentication token that looks like a small USB memory stick. The USB token simplifies the process of user authentication with a one-time password (OTP) and can be used by cloud services, organizations, and end users that require secure access to IT applications, including CoSign digital signature credentials.

Pairing the solutions creates a seamless, automated process for applying a standard digital signature. CoSign is a network-attached secure digital signature solution that allows the organization to choose its authentication scheme according to its own governance policy.  CoSign will not allow a user to apply his or her signature until the user is properly authenticated in compliance with the organization’s security policy and authentication scheme.

Identities re-authenticated prior to signing when combined with standard digital signatures are an extremely valuable set of tools for managing B2C businesses or cloud based business processes that must have trusted exchanges with customers online.

“There are many instances where businesses and government agencies may need to reach out to customers or citizens online,” said John Marchioni, general manager and vice president of business development, ARX.  “Yubico provides an advanced, reliable and trusted source for two-factor authentication so that organizations can have greater confidence in business processes executed in the cloud.”

CoSign’s digital signature technology is used to streamline and scale business processes in many vertical industries. ARX CoSign solutions are used by business and government customers to transition to a complete paperless workflow using legally enforceable digital signatures.
