密码术与防病毒策略的融合趋势

The Fusion Trend of Cryptography and Anti-virus Policy

密码术和病毒预防间的关系一点也不简单。自计算机病毒问题问世以来,人们已提出了不少涉及密码技术的解决方法;但实际上密码术目前只在防病毒中发挥较小的作用。另一方面,由于密码术在它所保护的对象内部为滤过性病毒提供了隐藏处,因此加密术也使得病毒预防更为困难。本文综述了加密技术同病毒预防和相关安全努力相抵触的现实。

This paper summarizes the conflicting facts between cryptography and virus prevention and related safety measures. Since computer virus came out, many solutions concerning cryptology have been raised. However, so far cryptology has made few contributions for virus prevention. On the contrary, as filterable viruses can hide in cryptographic files, it is more difficult to take precautions against virus.
