目前,在较为混乱的解密市场中,随着加密的最新技术不断出现、芯片烧断数据脚、解密开盖过程中存在的漏酸 的可能以及电路修改过程中误操作等,这些都有可能造成解密的失败;另外目前单片机的程序存储是靠内部电子 作为介质来存储的,当芯片使用周期比较长或受到外部强磁场等环境的影响,也会导致解密失败。如果采用纯软 件的方式破解,和母片的编程软件和编程方式甚至编程语言等有很大关系,也存在失败的概率。
但是,邦凯科技经过多年的研究,对AT87C52X2解密等单片机的算法、架构和工艺进行了深入的研究,精心设计 的解密技术流程在确保解密芯片绝对安全的同时,也把芯片解密的周期降到最低,极大的保证了客户在解密过程 中的工程控制和经济效益。
芯片解密、IC解密、单片机解密技术通常以高时间分辨率来监控处理器在正常操作时所有电源和接口连接的模拟特性,并通过监控它的电磁辐射特性来实施攻击。因为单片机是一个活动的电子器件,当它执行不同的指令时,对应的电源功率消耗也相应变化。这样通过使用特殊的电子测量仪器和数学统计方法分析和检测这些变化,即可获取单片机中的特定关键信息。
单片机解密探针技术是直接暴露芯片内部连线,然后观察、操控、干扰单片机以达到攻击目的。

AT87C52X2 概述
TS80C52X2 is high performance CMOS ROM, OTP, EPROM and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller.
The TS80C52X2 retains all features of the 80C51 with extended ROM/EPROM capacity (8 Kbytes), 256 bytes of internal RAM, a 6-source, 4-level interrupt system, an on-chip oscilator and three timer/counters.
In addition, the TS80C52X2 has a dual data pointer, a more versatile serial channel that facilitates multiprocessor communication (EUART) and an X2 speed improvement mechanism.
The fully static design of the TS80C52X2 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data.
The TS80C52X2 has 2 software-selectable modes of reduced activity for further reduction in power consumption. In the idle mode the CPU is frozen while the timers, the serial port and the interrupt system are still operating. In the power-down mode the RAM is saved and all other functions are inoperative.
