Abstract

Data security becomes one of the things that need to be considered. The Sum of Product (SOP) Encryption is one of simple algorithm. The SOP encryption is not a public-key system to encrypt data. it is almost unbreakable through brute force method and vulnerable to attack because the encryption models have a fixed pattern. However, this drawback can be avoided through the compression process to remove the pattern file. SOP encryption algorithm can use a Boolean algebra combination functions such as AND gate and OR gate. Simple algorithm in hardware language VHSIC Hardware Description Language (VHDL) is on data bits level. The purpose of this research is implementation of image encryption algorithm to produce a quick image encryption system. From result test, the image processing time without encryption average 4.999ns/px and 13.51ns/px with encryption.

Abstract

 Nowadays, Internet social media has enriched the way people to communicate and interact each other. Will it be possible for people to interact with their home appliances around? This paper proposes a new approach in smart home system that made possible for people to remotely interact with their appliances using social media networks. In this paper, we present a smart home prototype system that leverages Twitter’s Application Program Interface (API) to remotely control home appliances over the Internet. Experiment results showed that the system immediately responds to remote commands sent over a social media account to control home appliances. The system responds the command in 3672.96 ms. Publish-subscribe method work better in mass announcement communication system. Home system could notice all householders in less than 6 s independenly from number of householder. Our proposed method gives alternative solution to build reliable, fast and simple control method.
