如果您想更好的利用加密狗干工作或者其他方面,那对于一些问题就要来进行充分的了解了,下面浙大中控加密狗实施人员来为您讲解吧。
If you want to make better use of the dongle for work or other aspects, you need to fully understand some problems. The following is an explanation by the implementation personnel of zhongkong dongle of Zhejiang University.
问:微狗开发套件与软件狗有何区别?
Q: what is the difference between the micro dog development kit and the software dog?
答:主要区别为:并口狗和USB狗内置单片机,而软件狗则没有。
A: the main difference is that the parallel port dog and the USB dog have built-in microcontrollers, while the software dog does not.
问:单片机起什么作用?
Q: what is the role of single chip microcomputer?
答:单片机主要用来提高反跟踪的性能。它通过固化的软件(该软件不可读)对写入和读出的数据按一定的算法进行变换,并采用金天地公司独创的数据交换随机技术使得每次软件与狗交互的字节流都不一样(即使写入的数据是相同的)。这样就有效地防止了软件跟踪和逻辑分析仪的分析,保证了加密的可靠性。
Answer: single chip microcomputer is mainly used to improve the performance of anti tracking. It transforms the written and read data according to a certain algorithm through the solidified software (the software is unreadable), and uses the data exchange random technology created by Jintiandi company to make the byte stream of each interaction between the software and the dog different (even if the written data is the same). This effectively prevents software tracking and logic analyzer analysis, and ensures the reliability of encryption.
问:何为狗的密码及其作用?
Q: what is a dog's password and its role?
答:狗的密码是一种由软件开发者控制的、在对狗进行读写操作时校验的密码。狗的密码不影响检查及变换操作(DogCheck()、DogConvert())。微狗的密码为四字节长(32位),在出厂时密码设置为0。狗的密码可以由软件开发者用微狗开发套件发行盘上提供的工具软件(DogEdt32.EXE)进行修改。
Answer: the dog password is a password controlled by the software developer and verified when reading and writing to the dog. The dog's password does not affect the check and conversion operations (dogcheck(), dogconvert()). The password of the micro dog is four bytes long (32 bits), and the password is set to 0 at the factory. The password of the dog can be modified by the software developer with the tool software (dogedt32. Exe) provided on the distribution disk of the micro dog development kit.
注意:对修改后的密码一定要记录并保存好,若忘记密码,加密后的软件将无法对狗进行读写操作而导致软件运行失败。忘记密码后只能将狗送回至厂家进行清零。
Note: the modified password must be recorded and saved. If you forget the password, the encrypted software will not be able to read and write to the dog, resulting in the software failure. After forgetting the password, the dog can only be returned to the manufacturer for zeroing.

问:别人能买到和我买的一样的狗吗?他用他的随狗软件可以读出我在狗中写的内容吗?
Q: can others buy the same dog as I bought? Can he read what I wrote in the dog with his dog software?
答:您无需有此担心。狗中有一定的存储空间,其中一部分是系统区,另一部分是用户区。用户区可以供开发者读写,系统区用来存放狗的特征码及其它信息,任何用户都不能访问的。特征码是用来区分狗的一组数据,此数据在生产时随机产生,然后写到狗内。特征码重复的概率很小,只有几千万分之一。随狗的软件在对狗操作时,首先要检验狗的特征码,才能进行其它工作。所以随狗的软件和狗是一一对应的,别人的软件是读不出您在狗中写的内容的
A: you need not worry about this. There is a certain storage space in the dog, one part of which is the system area and the other part is the user area. The user area can be read and written by developers. The system area is used to store the dog's signature code and other information, which can not be accessed by any user. The characteristic code is a group of data used to distinguish dogs. This data is randomly generated during production and then written into dogs. The probability of repetition of the signature code is very small, only a few tens of millions. When the software with the dog operates on the dog, it must first check the dog's signature before other work can be carried out. Therefore, the software accompanying the dog and the dog are one-to-one correspondence. Other people's software cannot read what you write in the dog
问:能否带电插拔狗?
Q: can you plug and unplug the dog with power?
答:USB狗属于即插即用设备,可以带电插拔。
A: the USB dog is a plug and play device and can be plugged in and out with power.
