Abstract

Audit logs are very important part of any secure system and should be highly considered. The content of them which is past events is so sensitive and poses a threat to privacy and information security, so should be protected against any illegal reading and modification. The best way to do this is encryption. Important challenges in an encrypted audit log are speed of log and search process, correctness and semantic of search results and log size. In this paper a novel algorithm in order to build a secure searchable encrypted audit log by generating a record authenticator is presented. SQL command keywords along with their places, form record authenticator. Our new algorithm brings remarkable advantages such as: fast and high accurate search without decrypting any record, fast logging process, keeping tamper resistance of the log, decreasing log size and improving the correctness of search results by recognizing all irrelevant records in search time.
利用记录认证器建立高效、可搜索的加密日志
审计日志是任何安全系统中非常重要的一部分,应该得到高度重视。他们的内容是过去的事件是如此敏感,对隐私和信息安全构成威胁,因此应防止任何非法阅读和修改。最好的方法是加密。加密审计日志中的重要挑战是日志和搜索过程的速度、搜索结果的正确性和语义以及日志大小。本文提出了一种通过生成记录认证器来构建安全可搜索的加密审计日志的新算法。SQL命令关键字连同它们的位置,形成记录验证器。该算法具有快速、高精度的搜索,无需解密任何记录,记录速度快,保持日志的抗篡改性,减小日志大小,在搜索时间内识别出所有不相关记录,提高搜索结果的正确性等显著优点。
