The IEEE 802.15.4 is the most common standard development protocol that is applied to the current industrial wireless sensor network. Specific standards and requirement for IWSN has been regulated by international standard organization, which consider security as one of the most important parameters that need to be considered. The encryption method is a commonly used method in data protection on a wireless sensor network system, but nevertheless there are still several limitations that need to be improved. In this work, a stream cipher rabbit algorithm encryption was proposed as an alternative solution to securing IWSN for oil and gas industry sector. From simulation, the rabbit algorithm with a 50% shorter key length compared to the RC4 algorithm has shown, a better-quality security algorithm of 9% for the entropy and 25.56% from minimum standard avalanche effect compare to RC4.

Employee mobility is an important issue for companies that have a goal to become global company. The company often asks the employees to do some assignments outside the office area, either inside or outside of their home country. A portable virtual private network (VPN) is a device that enables the employees to perform remote access connection to internal computer resources via internet. Therefore, the employee can still work on their assignments in company server while doing business travelling. In this paper, the secure and low power portable VPN prototype is being proposed. The prototype of the VPN portable gateway device is built using OpenVPN-R core applications that are modified from OpenVPN version 2.3.10 with OpenSSL version 1.0.2h. It is implemented into a single board computer (SBC) Raspberry Pi 3 Model B +. The modification performed in this system is the inclusion of rabbit stream cipher algorithm to OpenSSL as one of the alternative options of TLS ciphersuites on OpenVPN. The prototype portable VPN gateway device generated from this research has rabbit ciphersuites, platform independent, and has additional features inbuilt firewall. The simulation results show that the proposed prototype can perform secure data transfer. On the other hand the proposed rabbit stream cipher algorithm shows better performance than other algorithm in terms of data transfer rate, CPU utilization, and memory usage which leads to smaller power consumption.
