DATABASE TRANSACTION LOG WRITING AND INTEGRITY CHECKING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18608834 titled 'DATABASE TRANSACTION LOG WRITING AND INTEGRITY CHECKING
Simplified Explanation
The patent application describes a method for writing transaction log entries to a database system within a trusted execution environment, with the transaction log stored outside of this environment. It also includes a method for restoring the database system using transaction log entries and a secure count.
- The method involves writing transaction log entries to a transaction log for a database system executed within a trusted execution environment.
- The transaction log is stored outside of the trusted execution environment.
- A secure count is maintained to track the number of transaction log entries written for committed transactions.
- The method also includes restoring the database system using transaction log entries and the secure count.
Key Features and Innovation
- Writing transaction log entries within a trusted execution environment.
- Storing the transaction log outside of the trusted execution environment.
- Maintaining a secure count to track transaction log entries for committed transactions.
- Restoring the database system using transaction log entries and the secure count.
Potential Applications
This technology can be applied in various database systems that require secure transaction logging and restoration processes.
Problems Solved

Using a secure count helps in efficiently monitoring and managing transaction log entries for committed transactions, ensuring data integrity and reliability.
Original Abstract Submitted
In various examples, there is provided a computer-implemented method for writing transaction log entries to a transaction log for a database system. At least part of the database system is configured to be executed within a trusted execution environment. The transaction log is stored outside of the trusted execution environment. The method maintains a first secure count representing a number of transaction log entries which have been written to the transaction log for transactions which have been committed to the database and writes a transaction log entry to the transaction log. In other examples, there is also provided is a computer-implemented method for restoring a database system using transaction log entries received from the transaction log and a current value of the first secure count.
