Abstract

A sensitive point in public key cryptography is how to protect the private key. We outline a method of protecting private keys using cryptographic camouflage. Specifically, we do not encrypt the private key with a password that is too long for exhaustive attack. Instead, we encrypt it so that only one password will decrypt it correctly, but many passwords will decrypt it to produce a key that looks valid enough to fool an attacker. For certain applications, this method protects a private key against dictionary attack, as a smart card does, but entirely in software.

软件智能卡通过加密伪装
如何保护私钥是公钥密码学中的一个敏感问题。我们概述了一种使用加密伪装保护私钥的方法。具体来说,我们不会使用一个太长的密码来加密私钥,因为密码对于穷举攻击来说太长了。相反,我们加密它,这样只有一个密码可以正确地解密它,但是许多密码可以解密它,从而产生一个看起来足够有效的密钥来欺骗攻击者。对于某些应用程序,这种方法可以保护私钥免受字典攻击,就像智能卡一样,但完全是在软件中。
