Data security is paramount for modern data centers. To protect sensitive data from cyberattacks and also from exfiltration after the devices are decommissioned. Several industry and government regulations mandate strict end-to-end data security framework. The data at rest encryption in an SSD is a key component of this framework. The implementation of these technologies in SSDs faces several challenges. One of them is related to fundamental limitations of the AEAD (Authenticated Encryption with Associated Data) algorithms used. This presents an overview about some of the challenges and mitigation strategies that SSD designs can deploy.
