The TrustME of China state electron? Safety shines put a technology to be in the applied case of domain of net of couplet of industrial other people

TrustME of China state electron? Safety shines put a technology to there is case of a lot of application in domain of net of couplet of industrial other people, among them typical is Hua Bang electron and ability of new Tang Ke, Qing Lianyun the cloud that collaboration rolls out arrives net of the couplet that carry matter solution. Relevant introduction is as follows:

• Plan is formed: This plan with new the Tang Dynasty small controller of safety of net of M2351SF content couplet is a foundation, use much chip to enclose, integrated small controller of safety of net of M2351 content couplet and Hua Bang W77Q TrustME? Safety shines put. New the Tang Dynasty M2351 small controller is core with Arm Cortex-M23 safe processor, use TrustZone technology. The stack of TinyTEE safety software that Qing Lianyun rolls out is inside the M2351 that gets TrustZone protection move.
• Working principle: Safety of Hua Bang W77Q shines put as small as M2351 controller to have link through adding close SPI interface, can prevent eavesdrop attack, ensure data passes the integrality that be defeated and security. W77Q safety shines put offer 32Mb safety to store, when OTA firmware is updated, can supply safe trustful chain, safeguard high in the clouds shows the data that collect to transmit safety to W77Q safety, be atttacked remotely not easily or cause privacy data to divulge.
• Functional advantage: This plan can offer facility status test and verify, safe memory, add builder of really close engine, random number to wait for complete content couplet network equipment governs a function, the TEE safety that accords with international standard to organize GlobalPlatform evaluates attestation, can ensure equipment of network of couplet of industrial other people arrives to the data of end is transmitted and store in the cloud the security in the process and dependability.
