Welcome to our AES256-XTS-STG series demo! Discover how AES-XTS encryption enhances NVMe SSD data security without compromising speed. <\/p>\n\n\n\n

Our AES256-XTS-STG-IP series offers efficient data encryption and decryption for various NVMe SSD speeds\u2014Gen3, Gen4, and Gen5. <\/p>\n\n\n\n

Experience outstanding write speeds up to 25.6 GB\/s, securing your data without performance loss. With no CPU or external memory required, it’s user-friendly and easy to implement.<\/p>\n\n\n\n

In a typical scenario, an NVMe SSD performs reads and writes to store user data.<\/p>\n\n\n\n

The data written to the NVMe SSD includes user data, and this data is stored on the SSD in a format that allows anyone with access to the NVMe SSD to directly read it.<\/p>\n\n\n\n

In other words, the data on the NVMe SSD is typically not encrypted by default, making it accessible to anyone who has physical access to the storage device.<\/p>\n\n\n\n

To enhance data security, data encryption has been implemented, and the chosen algorithm for encrypting data for storage is AES-XTS.<\/p>\n\n\n\n

This algorithm helps protect the data stored on the storage device, ensuring that it remains confidential and secure.<\/p>\n\n\n\n

DG offers AES256-XTS-STG as a solution for securing your data storage with high performance, without negatively impacting the transfer speed of NVMe SSDs.<\/p>\n\n\n\n

It’s designed to be user-friendly, it does not require a CPU or external memory, simplifying its implementation and operation.<\/p>\n\n\n\n

DG provides AES256-XTS-STG-IP demonstration with NVMe SSD on Agilex7 I-Series development kit.<\/p>\n\n\n\n

During the demonstration, the AES256-XTS-STG IPs are employed to showcase the encryption and decryption of data between the test logic and an NVMe SSD within an FPGA environment.<\/p>\n\n\n\n

This serves as a practical illustration of how the IP cores can secure data communication between these components.<\/p>\n\n\n\n

AES256-XTS-STG can encrypt data and decrypt data without significantly impacting the write and read speed of the NVMe SSD.<\/p>\n\n\n\n

This efficient encryption process ensures that data security is maintained without sacrificing the storage device’s performance.<\/p>\n\n\n\n

Write data to NVMe SSD<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

To measure the performance of data transfer, we\u2019ve designed a test logic to writes 32-bit incremental data pattern.<\/p>\n\n\n\n

When 156 GB data is written to 2 TB CFD Gaming Gen5 SSD, the outstanding write speed is displayed on serial console which is about 10,000 MB\/s.<\/p>\n\n\n\n

The results of capturing the incoming and outgoing pins of AES256-XTS-STG, it’s observed that the incoming data is 32-bit incremental data pattern, while the outgoing data is encrypted.<\/p>\n\n\n\n

Read data from NVMe SSD<\/h3>\n\n\n\n

Testing reads from the same SSD is conducted. 156-GB data is read and decrypted to user.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The report shows an outstanding write speed of 8,474 MB\/s.<\/p>\n\n\n\n

The results of capturing the incoming and outgoing pins of AES256-XTS-STG, it’s observed that the incoming data is encrypted, while the outgoing data is 32-bit incremental data pattern.<\/p>\n\n\n\n
