Intel SGX SDK通过ecall和ocall为SGX应用程序提供了一个函数调用机制.具体来讲,ecall是进入enclave去调用可信函数的操作,而ocall是退出enclave去调用不可信函数的操作[4].因此,用户应用程序可以通过调用ecall执行enclave内的代码,并获得返回值;enclave可以调用ocal...
(2) 更低的性能消耗:SCONE提供了一个安全C语言静态库接口用于透明的加解密I/O数据; 降低了因线程同步和系统调用导致的高性能消耗; 支持用户级线程和异步系统调用. 通过实验评估表明:SCONE能够通过SGX保护未被修改的应用程序, 并实现0.6~1.2倍的吞吐量. ...
计算机通过连接到系统总线的I/O设备与外部世界通信,如键盘、显示器和网卡。设备主要响应处理器发出的请求。但是,设备也能够发出中断请求,将外部事件通知处理器,例如用户按下键盘上的某个键。 中断触发将在2.12中讨论。在现代系统上,设备通过向特殊的总线地址发出写入来发送中断请求。中断被认为是硬件异常,就像故障一样...
