STORAGE DEVICE INCLUDING PROTECTED AREA AND DATA WRITE METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240354448 titled 'STORAGE DEVICE INCLUDING PROTECTED AREA AND DATA WRITE METHOD THEREOF
The abstract of this patent application describes a method for writing data in a replay protected memory block (RPMB) area of a storage device in response to a request from a host device. This method involves receiving a write request from the host device, which includes a message authentication code, data, and a bitmap index. The storage device then verifies the write request by calculating a message authentication code based on the data and bitmap index received from the host device, comparing it with the message authentication code of the write request, and checking the bitmap index against stored indexes to prevent replay attacks.
- Verifying write requests in RPMB area of storage device
- Calculating message authentication code based on data and bitmap index
- Comparing calculated code with request code for verification
- Checking bitmap index against stored indexes to prevent replay attacks
- Enhancing security and data integrity in storage devices
Potential Applications: - Secure data storage in mobile devices - Preventing unauthorized access to sensitive information - Protecting against replay attacks in storage systems
Problems Solved: - Ensuring data integrity in storage devices - Preventing unauthorized modifications to stored data - Enhancing security measures against replay attacks
Benefits: - Improved data security and integrity - Enhanced protection against unauthorized access - Increased trust in storage devices for sensitive information
Commercial Applications: Title: Secure Data Storage Technology for Mobile Devices This technology can be used in smartphones, tablets, and other mobile devices to ensure secure storage of sensitive data, such as personal information, financial records, and passwords. By preventing unauthorized access and replay attacks, this technology enhances the overall security of these devices, making them more reliable for users who value data privacy and protection.
Questions about Secure Data Storage Technology for Mobile Devices: 1. How does this technology improve data security in mobile devices? This technology enhances data security by verifying write requests in the RPMB area of storage devices, preventing unauthorized access and replay attacks.
2. What are the potential commercial applications of this technology? This technology can be used in smartphones, tablets, and other mobile devices to ensure secure storage of sensitive data, enhancing trust and reliability for users.
Original Abstract Submitted
a method of writing data in a replay protected memory block (rpmb) area of a storage device in response to a request of a host device includes receiving a write request, including a message authentication code, data, and a bitmap index, from the host device and verifying the write request based on the message authentication code and the bitmap index. the verifying the write request may include calculating a message authentication code based on data and a bitmap index received from the host device, comparing a message authentication code, calculated in the storage device, with the message authentication code of the write request, and comparing the bitmap index of the write request with bitmap indexes, stored in the storage device, to check whether a replay attack has been made.
