Abstract

With the widespread nature of wireless internet and internet of things, data have bloomed everywhere. Under the scenario of big data processing, privacy and security concerns become a very important consideration. This work focused on an approach to tackle the privacy and security issue of multimedia data/information in the internet of things domain. A solution based on Cryptographical Digital Signal Processor (CDSP), a Digital Signal Processor (DSP) based platform combined with dedicated instruction extension, has been proposed, to provide both programming flexibility and performance. We have evaluated CDSP, and the results show that the algorithms implemented on CDSP all have good performance. We have also taped out the platform designed for privacy and security concerns of multimedia transferring system based on CDSP. Using TSMC 55 nm technology, it could reach the speed of 360 MHz. Benefiting from its programmability, CDSP can be easily expanded to support more algorithms in this domain.

Highlights

We have entered the era of Big Data
We focused on solving the privacy and security issue of multimedia surveillance system in internet of things domain, where high quality video and audio recorded by cameras needs to be compacted, encrypted and transferred to the control center through network, and be replayed in real-time on the monitors
This paper proposes our approach and experiences for designing a platform based on Cryptographical Digital Signal Processor (CDSP), a clustered very long instruction word (VLIW) Digital Signal Processor (DSP) with ISA extension for cryptographic algorithms

Summary

Introduction

We have entered the era of Big Data. Since the process of multimedia communication systems involves data generation, storage, sending, receiving, sharing and so on, various security issues should be concerned. Data encryption algorithms could be adopted in multimedia communication systems to guarantee the security of data. Many kinds of data encryption algorithms have been released. This provides people with more options to choose according to their own needs. It imposes a challenge for hardware design to have a large level of flexibility to adapt to different kinds of data encryption algorithms with limited time
