Abstract: The emergence of large language model has greatly propelled the rapid application of artificial intelligence across various domains. In practice, however, there are a series of security and trust challenges in the applications of large language models caused by “model hallucinations”. These challenges make it difficult for practical applications to trust and adopt the results returned by the large language models, especially in securityrelated application domains. In many professional fields, we find that there lacks a unified technical framework to ensure the trustworthiness of results returned by large language models, which seriously hinders the application of largescale model technology in professional fields. To address this issue, a largescale model trusted application framework DKCF, integrating sufficient data (D), expertise knowledge (K), intellectual collaboration (C), and efficient feedback (F), is proposed. This framework is developed based on our practical applications in professional fields such as finance, healthcare, and security. We believe that DKCF can shed light on secure and reliable applications of large language models, and facilitate the intellectual revolution across various professional domains.

摘要： 大模型技术的出现极大推动了人工智能在各行各业的快速应用，但大模型在实际应用过程中面临着一系列由“模型幻觉”导致的安全可信挑战.这些挑战导致大模型应用落地时，尤其是安全攸关的专业性推理和研判时，其给出的结果难以被轻易信任采纳.在诸多专业领域实践中发现，大模型应用过程中缺乏一个统一的技术框架保证其结果的可信，严重阻碍了大模型技术在专业领域的应用. 针对这个问题，结合在金融、医疗、安全等专业领域的应用实践，提出一种集充足数据(data，D)、专业知识(knowledge，K)、能力协同(collaboration，C)、高效反馈(feedback，F)为一体的大模型可信应用框架DKCF. 希望DKCF可以推动行业大模型安全可信，助力大模型应用变革，推动越来越多的行业迎来革命.
