CPU refers to door, Intel publicly clarified-Intel, Intel,CPU-IT information

IT news , July 1, hardware security expert Damien Zammit has claimed that Intel's 32-bit processor (x86) has a subsystem, the system is able to play the role of secret back door.

Zammit said the backdoor built into Intel 32-bit processors of the Intel management engine (Intel Management Engine, ME), he believed that the engine is able to establish secret TCP/IP service, without the user's knowledge access Active memory, the engine cannot be closed.

Intel Security Chief technician Steve Grobman on the matter was clarified. He said Intel management engine is not the back door, but Intel to push firmware upgrade tool. Grobman pointed out that CPU design philosophy has greatly changed, the processor is just a block, each of which has its own role. The engine helps Intel and OEM manufacturers provide processors with the latest firmware upgrade of security in a timely manner.

CPU被指留后门，Intel公开澄清 - 英特尔,Intel,CPU - IT资讯

IT资讯讯 7月1日消息，硬件安全专家Damien Zammit此前声称英特尔32位处理器（x86）中拥有一个子系统，该系统能够起到秘密后门的作用。

Zammit所说的后门与英特尔在32位处理器中内置的英特尔管理引擎（Intel Management Engine ，ME）相关，他认为该引擎能够建立秘密的TCP/IP服务，在用户不知情的情况下访问活动内存，该引擎无法关闭。

英特尔安全部门的首席技术员Steve Grobman对此事进行了澄清。他表示，英特尔管理引擎并非后门，而是英特尔借以推送固件升级的工具。Grobman指出，CPU的设计理念已经发生很大改变，处理器仅仅是一块块积木，每个都有自己的作用。该引擎的存在有助于英特尔和OEM厂商及时为处理器提供最新的安全固件升级。
