Abstract

Application programs use randomized SQL statements can access the database and defend against SQL injection attacks in randomized SQL environment. This paper analyzed the challenges of randomization of SQL statements in application programs and proposed a SQL statement randomization method based on reverse data flow propagation. Reverse data flow propa-gation algorithm could quickly and accurately identify the SQL statements in application programs by tracing the data propagation of SQL statements in reverse, starting from the database operation function. Experiments show that the algorithm based on PHP 8.0 kernel recognizes SQL statements with an accuracy of 91.7%. The SQL statement randomization method based on reverse data flow propagation is more convenient and universal than the traditional method. Application processed by this method can be suitable for randomized SQL environment to defend against SQL injection attack.
