Desaware Licensing System は .NET のための暗号ベースのライセンスシステムです。サーバ / マシン毎とコンポーネントライセンスのために設計され、簡単な利用でき、手ごろでかつ高いセキュリティーシナリオのために構成を設定するることができます。128ビットの端末間接続の暗号のライセンスで、 Desaware Licensing Systemは隠しファイル、レジストリエントリあるいは他の外部の技術に依存しません。
Using unique security features in the .NET Framework such as strong named assemblies and XML signatures, the Desaware Licensing System relies on end to end cryptographic techniques, avoiding the use of hidden files, registry entries and other traditional licensing schemes.
A selection of the new features in this product include:
The Desaware Licensing System is itself licensed on a per-server/development system basis using its own technology.
The Desaware Licensing System is designed for per-machine licensing of applications or components. Installation codes are generated on a server for use during installation of Microsoft .NET Framework-based applications and components. During activation, the code is verified by the server before it issues a licensing certificate bound to the client machine. The Microsoft .NET Framework technology prevents techniques traditionally used to avoid licensing (modifying programs or substituting alternate licensing code). XML signatures prevent modification of the certificate, and certificates will only work on the machine for which they are created. The server controls how many systems each installation code supports, allowing for licensing multiple machines using a single installation code. The result is hardware quality security, without the use of external hardware.
