    Abstract: A processor is adapted to manage security risk by updating and monitoring a taint storage element in response to receipt of taint indicators, and responding to predetermined taint conditions detecting by the monitoring. The processor can be operable to execute instructions of a defined instruction set architecture and comprises an instruction of the instruction set architecture operable to access data from a source and operable to receive a taint indicator indicative of potential security risk associated with the data. The processor can further comprise a taint storage element operable for updating in response to receipt of the taint indicator and logic. The logic can be operable to update the taint storage element, process the taint storage element, determine a security risk condition based on the processing of the taint storage element, and respond to the security risk condition.

    Abstract translation: 处理器适于通过响应于接收到污点指示器而更新和监视污染存储元件以及响应由监视检测到的预定污点状况来管理安全风险。 处理器可操作以执行定义的指令集架构的指令,并且包括可操作以从源访问数据并且可操作以接收指示与数据相关联的潜在安全风险的污点指示符的指令集结构的指令。 该处理器可以进一步包括一个可用于响应于接收到该污点指示符和逻辑而进行更新的污物存储元件。 逻辑可以用于更新污染存储元件,处理污染存储元件,基于污染存储元件的处理来确定安全风险状况,并响应安全风险状况。
