Hidden Markov model based method for detecting assembler instruction level vulnerability

The invention relates to a hidden Markov model based method for detecting assembler instruction level vulnerabilities, belonging to the technical field of information security. The method comprises the following steps of: (1) constructing a vulnerability instruction library (VIL); (2) respectively selecting a plurality of executable programs with the vulnerability as training data of the vulnerability for each vulnerability in the vulnerability instruction library by aiming at all the vulnerabilities in the vulnerability instruction library constructed in the step (1); (3) obtaining assembler instruction segments of the training data of each vulnerability in the vulnerability instruction library; (4) obtaining a numerical code sequence of the training data; (5) sequentially obtaining a parameter lambda r=(Ar, Br, pi r) of the corresponding hidden Markov model of each vulnerability in the vulnerability instruction library; and (6) recognizing the vulnerability of an executable program to be detected. Compared with the prior art, the hidden Markov model based method for detecting the assembler instruction level vulnerability has the following advantages of establishing a model for the assembler instruction with context correlation and recognizing vulnerability characteristics by using the HMM (Hidden Markov Model) for the first time, increasing vulnerability detection efficiency and reducing error report rate and missing report rate.

Official document error correction method

The invention discloses an official document error correction method, which comprises the following steps of: a text detection step: carrying out text recognition model training by utilizing machine learning, and classifying document texts into notification, report, approval, notification, letter, conference summary and ask-for-leave types; an error detection step: making word segmentation througha Chinese word segmentation device, detecting errors from the aspects of word granularity and word granularity, integrating suspected error results of the two types of granularity detection, to forma suspected error position candidate set; using a bidirectional character-level N-gram LM deep learning model for scoring characters in sentences, regarding the position with the low score as a position to be corrected, conducting dictionary word checking on the position to be corrected and context combinations, and when all the combinations cannot be found in a dictionary, regarding the combinations as wrong characters and added into a wrong position candidate set. According to the scheme, auditing requirements such as row text specifications, incomplete contents, unknown questions, grammar error correction, smoothness detection, context association and the like are combined, the characteristics are used for innovating, reconstructing and combining the existing technical scheme, and the error correction effect of the enterprise electronic official document can be effectively improved through tests.
