受基因理论启发的计算机病毒进化模型

作为一种重要的网络空间安全威胁，计算机病毒及其生存与繁衍一直是网络空间安全领域研究热点。该文借鉴生物基因理论和人工生命思想，提出了一种基于基因理论的计算机病毒进化模型:给出了计算机病毒形式化定义，构建了计算机病毒在基因、DNA、染色体等3个层次的进化数学模型，以模拟计算机病毒在自然选择中的进化模式。仿真实验表明，即使遭遇严酷的外部环境，具有算法特性与生命特性的计算机病毒仍具极强的进化能力。

Gene-Inspired Model for Computer Viruses Evolution

As an important sort of cyberspace security threats, computer viruses have been a hotspot in cyberspace security research. Inspired by the gene theory and the artificial life theory, we present a gene-based model of computer viruses evolution. The form definition of the computer virus is given and the mathematical models of computer viruses evolution in the three levels of gene, DNA, and chromosome are constructed. And then the computer viruses evolution process in natural selection is simulated. Experimental results show that, even in face of harsh external environment, computer viruses which have characteristics of both algorithm and life still have strong ability of adaptation and evolution.
