Non-repudiated Time Source Adds Additional Dimension of
License Flexibility and Security
May 3, 2006 - Sentinel Hardware Keys Real Time Clock (RTC), a software rights management token that protects software vendors from unauthorized use or distribution of their products and includes a non-repudiated time source.
Sentinel RTC Keys contain a clock stored inside the hardware key that allows software developers to reliably and securely offer time-based license models such as trial, demo or subscription. With Sentinel RTC Keys, developers are able to meet their customers' needs for flexible time-based licensing while protecting their revenue streams with the highest level of protection against time tampering. RTC Keys also allow end users to place timestamps (hours, minutes, seconds) and date (day, month, year) on the output of an application for definitive time recording purposes.
"The availability of Sentinel Hardware Keys with a physical clock increases the high level of security because the key does not need to rely on the users' system time," said Eric Gruenke, Security Analyst at Hal-Tec Corporation. "Hal-Tec was concerned about the vulnerability of the communications pipe between the hardware token and the software application. We considered different products and found the Sentinel Hardware Key to be the most secure token available particularly because of the encryption protecting the communications."
Sentinel Hardware Keys are the first to incorporate public key cryptography, AES encryption and internal authentication. The result is an ultra-secure hardware token that still offers the highly flexible licensing for which the Sentinel product line is known. Additionally, with Sentinel Business Layer APIs™, developers can obtain the highest level of security and control over license designs without spending time on lower level programming.
With the real time clock, software developers using Sentinel Keys now have the highest level of protection against time tampering in addition to the strongest security for protecting their intellectual property.
Sentinel Hardware Keys, the industry-leading hardware tokens which, when attached to a computer or network, monitor and enforce the licensing of products which have been protected using this solution. Sentinel Hardware Keys deliver military-grade security through public key cryptography, AES encryption and internal authentication.
