密码管理器系统的设计

Design of Password Manager System

随着计算机网络在人们的日常生活中所占的比重越来越大,输出信息环境的安全就变得至关重要。在信息交流传输中,常面临信息被截获,中断,篡改,伪造的威胁。为保障信息安全,密码加密因而出现,把明文通过密匙加密变成密文传送的方法就更加安全。为了使加密的安全系数更高,更多的密码算法不断的被创造,与此同时,密码被破解的威胁就变得越来越普遍。针对这种现象,人们采取加入字母字符、用繁杂的方式组合密码等方法,为自己的讯息创造更高的安全系数。这也让密码的组合方式更加多样,而记忆密码的负担也愈发沉重,一个方便记忆、设置密码的工具就变得帮助巨大。本文以人们丢失密码的具体情境为出发点,设计一个既可以记忆密码又可以保证安全的密码管理器以解决这一问题。

With the increasing proportion of computer networks in people's daily lives,the security of the output information environment becomes critical.In the exchange of information,we often face the threat of interception,interruption,tampering and forgery of information.In order to ensure the security of information,password encryption has emerged.It is more secure to convert the plain text into encrypted text by encrypting it with a key.In order to make the encryption more secure,more cryptographic algorithms have been continuously created,and at the same time,the threat of password cracking has become increasingly common.In response to this phenomenon,people have adopted methods such as adding alphabetic characters and combining passwords in a complicated manner to create a higher security factor for their own messages.This also makes the combination of passwords more diverse,and the burden of remembering passwords is getting heavier.A tool that is convenient to remember and set passwords has become hugely helpful.This article takes the specific situation where people lose their passwords as a starting point,and designs a password manager that can both remember passwords and ensure security to solve this problem.
