A method on safe data transmission with lossless compression
Ying Shi, Shuang Zhang · 2012
We propose a method on safe data transmission for the embedded system, which is convenient and of high computational efficiency. This method not only removes the redundancy by re-encoding the not frequently changed information between two adjacent data, but also encrypts the frame by Rivest-Shamir-Adleman (RSA) algorithm after scrambling it with a random matrix. The experimental results show a good security of data transmission and a certain compression effect. Due to the slow variance in the collected data of embedded system and the existence of large historical data redundancy, the method mentioned above is more suitable for the embedded system than the conventional methods.
