Implementing Memory Encryption To Protect Data In Use


In my blog “The Methods of Memory Encryption to Protect Data in Use,” I discussed how the XTS/XEX mode of encryption was the appropriate choice for protecting data stored in and accessed from memory, also known as, protecting data in use. As a quick recap, XTS/XEX uses two keys, one key for block encryption, and another key to process a “tweak.” The tweak ensures every block of memory i... » read more

Maximize Memory Security Of HPC SoCs With Efficient Crypto IP


Data that is created and transferred between billions of devices and the cloud is growing exponentially. More and more devices are entering the market, the cloud is expanding to the network edge and new applications are emerging. These factors are drivers for technological advances in high-performance computing (HPC), reshaping system-on-chip (SoC) designs to address the need for more accelerat... » read more

The Methods Of Memory Encryption To Protect Data In Use


In my blog “The Importance of Memory Encryption for Protecting Data in Use,” I discussed the growing industry consensus on the imperative of incorporating memory encryption in computing architectures. In part two of this series, I’ll explore the cipher algorithms and modes that can be used to protect data stored in and accessed from memory, or in other words, used to protect data in use. ... » read more

The Importance Of Memory Encryption For Protecting Data In Use


Nowadays, as SoC (System-on-a-Chip) systems become more and more complex, security functions must grow accordingly to protect the semiconductor devices themselves and the sensitive information residing on or passing through them. While a Root of Trust security solution built into the SoCs can protect the chip and data resident therein (data at rest), many other threats exist which target interc... » read more
