Abstract: In the era of Big Data, the demand for secure data storage is rapidly increasing. To accelerate the complex encryption computation, both specific instructions and hardware accelerators are adopted in a large number of scenarios. However, the hardware accelerators are not so effective especially for small volume data due to the induced invocation costs, while the AES-NI (Intel® Advanced Encryption Standard New Instructions) is not so energy efficiency for big data. To satisfy the diversity performance/energy requirements for intensive data encryptions, a collaborative solution is proposed in this work. We proposed a feasible hardware-software co-design methodology based on the stack file system eCryptfs, with QAT (Quick Assist Technology), which is named as ACA-SDS: Adaptive Crypto Acceleration for Secure Data Storage. ACA-SDS is able to choose the optimal encryption solution dynamically according to file operation modes and request characters. Adjustable parameters, such as α, β and M are provided in our scheme to provide a better adaptability and trade-off choices for encryption computation. Our evaluation shows that ACA-SDS can get 15%-25% performance improvement for big-data blocks compared with only software or hardware accelerations. Furthermore, our methodology provides a wide range of practical design concepts for the further research in this field.
