    • A technique is provided for generating and interpreting secure and system dependent software license keys. According to one or more embodiments of the present invention, a device executing an encoding algorithm may generate a software license key by applying several layers of security. Illustratively, the device may initially define a license data representing a software license for the software. The device may also compute an authentication code based on a unique identification of hardware upon which the software is configured to operate. The license data and authentication code may be combined and encrypted into an encrypted result, which may be transformed into a software license key (e.g., human readable). Also, the device may apply a predetermined encryption technique (e.g., cipher) during the transformation as an additional layer of security. Conversely, a device configured to operate the software may execute a decoding algorithm to interpret the software license key similarly in reverse.
    • 提供了一种用于生成和解释安全和系统相关软件许可证密钥的技术。 根据本发明的一个或多个实施例,执行编码算法的设备可以通过应用几层安全性来生成软件许可证密钥。 说明性地,设备可以最初定义表示软件的软件许可证的许可证数据。 该设备还可以基于软件被配置为在其上操作的硬件的唯一标识来计算认证码。 许可证数据和认证码可以被组合和加密成加密的结果,其可以被转换成软件许可证密钥(例如,可读的)。 而且,该设备可以在转换期间应用预定的加密技术(例如密码)作为附加的安全层。 相反,配置为操作软件的设备可以执行解码算法以相反地类似地解释软件许可证密钥。
