Encryption method and smart home system

Abstract

The invention provides an encryption method and a smart home system. The method comprises the steps that a sending device sends transmission encryption data to a receiving device; the method only comprises the following steps: generating a first random number by the sending device, processing the first random number and original data to obtain first encrypted data, segmenting the first encrypted data to obtain a plurality of segmented data, segmenting the first random number to obtain a plurality of segmented random numbers, and pairing the segmented data and the segmented random numbers to obtain a paired data pair; processing the segmented data and the segmented random numbers corresponding to the segmented data to obtain segmented encrypted data, merging the segmented encrypted data to obtain second encrypted data, calculating check codes of the second encrypted data and the first random number, merging the first random number, the second encrypted data and the check codes to obtain transmission encrypted data, and transmitting the transmission encrypted data to the server. And sending the transmission encryption data to the receiving equipment. According to the method, when the receiving equipment is provided with the small processor for decryption, excessive processor resources do not need to be wasted for processing.
