Rambus DAR (previously MatrixDAR from Inside Secure) is a high performance, FIPS 140-2-certified encryption solution that protects data-at-rest (DAR) in today’s Android smartphones and tablets. DAR provides full disk encryption to both the device and its removable storage media. It allows Android device manufacturers to quickly and cost effectively integrate FIPS140-2 certified encryption capabilities to meet the demanding requirements of carriers and governments.
256-bit encryption strength and hardened key management
FIPS and NIST Compliance
FIPS 140-2-certified cryptographic module and NIST compliant key management
Taking full advantage of multi-processors to ensure top performance
DAR replaces native Android cryptographic libraries with a FIPS cryptographic module (FIPS140-2 certificate #2389).
DAR takes special care of properly protecting the encryption key. The key is protected by a FIPS-certified crypto module in compliance with NIST Special Publication 800-132. As the crypto module is running in the user space, the keys are not distributed in both user space and kernel, as in the native Android solution. Instead, only a key identifier is passed to the kernel.
DAR integrates seamlessly in Android devices to provide higher security without modifying the existing user interface.
Despite using higher-strength encryption, DAR has consistently delivered a read-and-write performance better than the native Android solution. The data encryption (XTS-AES with 256-bit strength) is accelerated using native instruction set on ARMv8 or on x86 (AES-NI).
