Sentinel Hardware Keys now support Microsoft Windows Vista.

Secure Communications

Sentinel Hardware Keys are the most secure hardware token available in the world. Both public key cryptography and 128-bit AES encryption are used to secure communications between the key and the protected application. Middle layer attacks such as record and playback, and driver emulation are effectively stopped. A unique encryption key is used for every communication session between the application and the hardware token, making brute force attacks virtually impossible. In addition, the keys include internal authentication, which effectively prevents cloning of the keys.

Speed Implementation - Business Layer APIs™

The best implementation of any protection scheme should include complete integration into your application through APIs. By using Sentinel Business Layer APIs, you can obtain the highest level of security and control over sophisticated license designs without spending time on lower level programming. Business Layer APIs are pre-configured, higher level APIs for popular license models such as subscription, evaluation and pay-per-use. These tools typically reduce the programming time required to secure a new application by up to 60% or more compared to other hardware key solutions.

Quickly Add Protection - Sentinel Shell

Sentinel Hardware Keys are the first to enable wrapping protection for Microsoft .NET framework version 2.0, in addition to the most commonly used platforms. The Sentinel Shell offers a way to quickly add protection and obfuscation to your application without requiring any alteration to the source code. With the Sentinel Shell, you can enhance overall security by adding multiple layers to thwart hacking attempts, preventing memory dumping and protecting against debuggers. The Sentinel Shell enables you to embed licensing and protect your application in minutes, even if don't have access to source code.

Simplify Updates and Activation

Sentinel APIs also include Logical Addressing which allows developers to add or change implementations without being concerned about specific memory address usage. This greatly speeds development time as well as reducing risk of error from overwriting information in memory cells.

With Sentinel Hardware Keys, you can also program multiple keys at once and customize license models at the production stage. License configuration can be altered without requiring further development changes. Sentinel technology allows ISVs to send updates or additional licenses to keys in the field in a secure, controlled manner. Updates are sent using the same high level of security as communications between the hardware token and the software application.

Implement Time-Based Licensing - Sentinel V-Clockk™

The Sentinel Hardware Key V-Clock allows you to reliably and securely offer time-based license models such as trial, demo or subscription. Sentinel V-Clock resists time tampering and requires no on-board battery, enabling secure time-based licensing without added costs.

Secure Your Distribution Channels - Sentinel Distributor Keys™

Sentinel Hardware Keys allow you to carefully control and regulate your distribution channels through the use of Distributor Keys. You can assign and securely imbed encryption keys during the manufacturing process in order to control the creation of licenses through your channels.
