    • Methods for using integrity checking techniques to identify and locate computer viruses are provided. A method for virus localization for each of three types of virus infections is provided, including the steps of computing a sequence of file blocks, calculating hashes for the sequences of file blocks from a host file and calculating hashes for the same or related sequences of file blocks from an infected file, and comparing the hashes from host file to the hashes from the infected file from the same or related sequences of file blocks such that when some of said first hashes and said second hashes do not match, a location of a virus is output. Methods are provided for computing the sequence of file blocks depending on the type of virus infection, and for calculating the hashes using a collision resistant hash function, a digital signature scheme, a message authentication code, or a pseudo-random function.
    • 提供了使用完整性检查技术来识别和定位计算机病毒的方法。 提供了用于三种类型的病毒感染中的每种病毒定位的方法,包括计算文件块序列的步骤,从主机文件中计算文件块序列的散列,以及计算相同或相关文件序列的散列 来自被感染文件的块,并且将来自主机文件的散列与来自受感染文件的散列从文件块的相同或相关序列进行比较,使得当所述第一散列和所述第二散列中的某些不匹配时,病毒的位置 被输出。 提供了用于根据病毒感染的类型来计算文件块序列的方法,以及使用防冲突散列函数,数字签名方案,消息认证码或伪随机函数计算散列的方法。
