航空数据存储卡毁钥能力评价方法研究

为满足复杂战场态势下机载数据的安全性需求，需要建立对航空数据存储卡毁钥能力有效评价的方法。 建立航空数据存储卡毁钥能力有效性评价的目的是保证航空装备信息安全的重要措施，是科学、准确评价毁钥 设计是否满足需求的重要手段，是航空装备定型列装前必要的信息安全测评过程。通过对航空数据存储卡的典 型结构和硬件毁钥原理进行分析，对毁钥后电学、物理和化学等技术手段进行深入的研究，提出一种针对航空 数据存储卡毁钥能力的评价方法，从数据存储卡读取能力和存储介质损毁状态两个过程对毁钥效果开展评价， 从而规范了当前测评机构对数据存储卡毁钥能力评价过程中无统一方法的现状。本文利用该评价方法对某样品 航空数据存储卡经硬件毁钥试验后开展毁钥效果分析，验证方法的有效性。航空数据存储卡毁钥能力评价方法 可以很好的评估毁钥设计的效果，确保机载数据的安全。

Research on the Evaluation Method of Destroyed Key Abilityof Aviation Memory Card

To meet the safety requirements of airborne data in complex battlefield situations, it is necessary to establish an effective evaluation method of destroyed key ability of aviation memory card. The purpose of establishing the effectiveness evaluation of destroyed key ability is to ensure the information security of aviation equipment. It is of great significance to scientifically and accurately evaluate whether the destroyed key design meets the requirements. It is also a necessary information security evaluation process before aviation equipment finalization. The typical structure and the hardware destroyed key principle of aviation memory card are analyzed. By studying electrics, physics and chemistry analysis methods behind hardware destroyed key, an evaluation method for the destroyed key ability of aviation memory cards is proposed. The destroyed key effect is evaluated from the readability of the aviation memory card and the damage status of the storage medium. It standardizes the current situation that there is no unified method for the evalu-ation of the destroyed key ability by the evaluation organization. The effectiveness of the evaluation method is verified through practical application in analyzing the destroyed key effect of an aviation memory card after the hardware destroyed key experiment.
