Large Language Models (LLMs) have revolutionized Generative Artificial Intelligence (GenAI) tasks, becoming an integral part of various applications in society, including text generation, translation, summarization, and more. However, their widespread usage emphasizes the critical need to enhance their security posture to ensure the integrity and reliability of their outputs and minimize harmful effects. Prompt injections and training data poisoning attacks are two of the most prominent vulnerabilities in LLMs, which could potentially lead to unpredictable and undesirable behaviors, such as biased outputs, misinformation propagation, and even malicious content generation. The Common Vulnerability Scoring System (CVSS) framework provides a standardized approach to capturing the principal characteristics of vulnerabilities, facilitating a deeper understanding of their severity within the security and AI communities. By extending the current CVSS framework, we generate scores for these vulnerabilities such that organizations can prioritize mitigation efforts, allocate resources effectively, and implement targeted security measures to defend against potential risks. 展开更多

唐诗一字平仄两读而义有异同问题之二——唐诗一字平去两读而义同问题论析 被引量:3

文章对唐诗中48个单字具有词义不变而可变调为平去两读的特殊用法作出论析,认为:(一)诸字的平去两读,唐诗中实有常读与偏读之分,但偏读不能忽视,否则会误读唐诗,曲解声律。其中31字以平声为常读,17字以去声为常读。今音一读是对常读的... 文章对唐诗中48个单字具有词义不变而可变调为平去两读的特殊用法作出论析,认为:(一)诸字的平去两读,唐诗中实有常读与偏读之分,但偏读不能忽视,否则会误读唐诗,曲解声律。其中31字以平声为常读,17字以去声为常读。今音一读是对常读的继承。(二)其中8字表示名词义,9字兼表名、动(或形)义,30字表示动词义,1字表示副词义。可据这种音义关系掌握各字用法。(三)一字平去义同适应了唐诗用韵和格律平仄的需要,为诗人依律用字提供了更为自如的选择余地。这种用法始于魏晋南北朝,而兴盛于唐代,后代虽仍延用,但仅限于少数常用字。 展开更多
