Frequency of chip flaw problem is sent, was turn for Ying Weida this. Defeat solution technically to hold the post of heaven (Nintendo) the flaw detail that Switch sport lead plane announced a name to be E of é of Fus é E Gel a few days ago with implementing the ReSwitched group that contains software, this is conceal in chip of Nvidia Tegra X1 of core of Switch lead planeSafeFlaw, will allow be astonished guest to implement aleatoric form, and allege cannot repair namely after lead plane leaves factory. Since 2018, intel, AMD was introduced to by chip flaw problem early or late where the wind and the waves are highest, chip flaw is ceaseless by exposure, also let at present networkSafeThe problem makes target of public criticism, want performance or want security, it is a proposition that needs a balance to chip manufacturer.

Chip flaw initiates a trade attention

The chip 2018The marketBe destined one year be rough every, the core segment of resurgence offers event here fermenting continuously, tycoon of a few big chip there exposes to the sun often a chip flaw problem.

Nvidia Tegra chip exposed to the sun recently flaw, first years the Switch of Ren Tiantang new leader with respect to make a great coup used put on sale chip of NVIDIA Tegra X1, according to media coverage, the gold of Mu of peaceful of road of beautiful jade of triumphant a twenty-five-stringed plucked instrument of ReSwitch hacker group (Katherine Temkin) the flaw in announcing she uses chip of NVIDIA Tegra X1 is broken saw Switch lead plane, this flaw allows anybody to run aleatoric code on its, this is meant abstain system and pilfer editionSoftwareCan move at will. According to technical documentation, in the Bootrom of chip of consist in of this one flaw, EquipmentAfter leaving factory, cannot seal through the patch, hold the post of heaven to also do not have a law to pass namelySoftwareWill newlier repair it, only repair method is to return a factory to replace processor. Simple for, the flaw that discovers this is a blemish of the chip of Ying Weida Tegra X1 that use. It is Ren Tiantang not just, all use of this chipEquipmentWill be affected.

Because this flaw is the consist in area that start, have repair impossibly through simple patch procedure so. This also is meant, theoretic, switch of existent all Ren Tiantang is OK and perfect broken solution.

Besides Nvidia, in January 2018, intel chip is exploded to give existence technology blemish to cause great and safe leak, the hacker can use this flaw to read take equipment memory, obtain the sensitive information such as password, close key. Two designs flaw is called ” fusing ” (Meltdown) and ” ghostliness ” (Spectre) . Former the applied program that allows level of low attributive, user ” cross the border ” the memory that visits systematic level, latter can have cheated safety to check an order, make apply a program to visit the aleatoric place of memory. Among them, “Specter ” the chip that affects AMD, ARM, Ying WeidaProduct, affect almost world of whole computer processor. “Specter ” flaw, be thought to will surely not get be settlemented thoroughly inside several years. Malic company response says, all Mac and IOS system will be affected. To this, malic Ceng Hui should say, all Mac and IOS system will be affected, because the Mac computer of malic company and partial IPhone all use Intel chipProduct.

One is not made the same score, one rises again, germany records of a computer exposed to the sun recently piece, researcher says to find 8 new flaw between computer CPU chip again, these flaw and before the Intel chip hole that makes bubbling with noise ” Meltdown ” and ” Specter ” special likeness, researcher expresses, intel has prepared to give out a patch to go repair these flaw, of course, ARM also is done not have this by escape by sheer luck, its a few chip also got affect.

Actually, intel is some earlier this year moment is mentioned in statement, flaw is not Intel of bureau be confined to, include the friendly business such as AMD, ARM to also be put in similar problem. Just as one would expect, be exposed to the sun besides Intel outside major flaw, CTS Labs of company of an Israel security also issued a safe white paper recently, point out among them, computer chipMakeAMD is put in 13 safe flaw in the chip of carry out on. According to the report, the flaw that CTS reveals this needs to obtain administrator attributive ability to be discovered, these flaw involve processor of center of data of mobile processor of processor of processor of AMD Ryzen desktop, Ryzen Pro company, Ryzen, EPYC, the platform of different flaw correspondence is different, had been succeeded to use below 21 kinds of environments among them, still have the possibility that 11 existence are used.

Chip flaw entail untold troubles

As ” chip flaw door ” ferment with upgrade, its consequence and affect limits also is estimated hard. In the beginning of the year ” flaw door ” in incident, although be Intel,give priority to, but this crosses a manufacturer, cross national boundaries, crossFramework, the major flaw incident that crosses an operating system, swept across whole IT industry almost. Connect ARM, high, the chip of processor of major main trend such as AMD also is affected by flaw, the processor of IBM POWER detail is influential also. The terminal unit such as server of the mainstream operating system such as the Windows that uses these chip, Linux, MacOS, Android and computer, flat computer, mobile phone, cloud suffers the effect of afore-mentioned flaw.

Current, we existed much information with digital form personal computer and high in the clouds. The design flaw that comes from processor can cause these data to be mixed to abuse by theft, bring about user loss personal property. The expert warns network safety, the industry that use cloud computation serves may be assaulted easily especially. If aggressor pays a certain field that this kind of service is able to enter after cost, they obtain the information of other client likely, for instance, bit money exchange, process of gregarious chatting application, many even government orgnaization, metropolis general password or it is data storage is on cloud server. The hacker passes the boy or girl friend that atttacks cloud service likely, bit money purse is possible by filch, the important data of governmental orgnaization flows to a hacker possibly also from this.

The enterprise such as Yamaxun, Microsoft, Gu Ge is affected in succession. Below Yamaxun’s AWS or the cloud service that are Microsoft, Gu Ge, user of same server connective group in, if hacker attack used a device, they can read the data that takes another device that uses same chip likely. The industrial catenary of the high-grade such as computation of net of prospective content couplet, cloud, artificial intelligence has the figure of chip. And in these chip if haveHardwareThe existence of the trojan, once spark,will bring about data invalidation of missing, function even the system breaks down.

Hole of shot-off of loss needs whole industry effort

Manufacturer people seeking chip rate while, to information safety also cannot treat sth lightly, but if where,two respects get efficiency and security evenly, still need discreet processing. “Spectre ” gram of Paul road section points out one of detector, “Ghostliness ” of the influence is microprocessor of almost all high speed, they are brought about to appear easily to the high demand of speed when designing new chip safe problem. “Whole industry hopes to had been jumped over more quickly all the time, achieve security at the same time. But ‘ ghostliness ‘ make clear, fish and bear’s paw cannot hold concurrently… this is a meeting asHardwarethe problem that lifecycle worsens ceaselessly. “

Industry also has an analysis to think, relevant rehabilitate patch will affect the operation rate of processor. Linux system develops personnel to express, the rehabilitate of safe to chip flaw will affect operating system traversal speed, typical performance drops extent is 5% . How is American land entirely in a statement say, safe patch is to settle the protective way with chip best flaw, but function of the computer after hitting a patch may drop amount to 30% , and chip flaw is by central processorFrameworkSoftware of and rather than is caused, hit a patch so and can not solve chip flaw thoroughly. If security asks the problem solved a result to bring about CPU function to change however,differred, is this to the loss outweights the gain?

To this, a few experts also express, each are at present big the supplier was offerred alleviate accordingly measure, although reduced the risk that chip is atttacked, but also be only ” take temporary solution not effect a permanent cure ” . What they need to consider more is, whether do next generation products need to change new framework, solve this kind of problem from essential before last thereby.

Chip flaw already was become ” caustic of one caustic all ” entire industry event, those who need whole industry catenary is close cooperate, solve jointly. Solve well, everybody head off a danger, and in case occurrence safety atttacks incident, those who damage is Intel or which manufacturer not only, however whole industry.
