    • To provide for cryptographic separation, embodiments of the invention employ containment mechanisms provided by trusted operating systems to ensure that plaintext data which must be encrypted in accordance with a security policy (or, in reverse, ciphertext data which is to be decrypted) is processed by a suitable encryption routine before being sent onwards for transmission, storage, or the like. Such containment mechanisms usually include mandatory system access control rules which specify to which system resources the output of a system resource (such as an application) may be supplied. By specifying a suitable set of such rules, mandatory encryption can be enforced at the operating system kernel level.
    • 为了提供加密分离,本发明的实施例采用由可信操作系统提供的保密机制,以确保必须根据安全策略(或相反地,要被解密的密文数据)加密的明文数据由 在向前发送以进行传输,存储等之前的适当的加密例程。 这种容纳机制通常包括强制性系统访问控制规则,其规定可以提供系统资源(例如应用程序)的输出的哪个系统资源。 通过指定一套合适的规则,强制加密可以在操作系统内核级别执行。
