SECURING AUTOMATED OFFICE USING ADVANCED SECURITY METHODOLOGIES

Information Technology

In recent years, internet use is increased tremendously. Many devices such as smartphones and laptops are constantly connected to the internet daily for a long period of time. Also the Internet of things(IOT) has gained importance due to its wide range of applications. Therefore, many industries are acquiring IoT in their offices. Devices used in IOT such as sensors transfer data over the network all the time. This data is sensitive information. If this information is leaked, there might be a large threat to the industry. Therefore, Security and privacy issues occur in IOT which have been described as the most challenging problems in the IoT domain. We propose an Automated office system as a module for implementing secure data transfer over the network. The system controls fans and lights by constantly detecting temperature of the room and light present in the room. If the system detects smoke in office premises it sets the alarm off. If any intrusion is detected, the alarm is set and a notification is sent to the owner's mobile app. To enter the office the user needs to enter the password and after 3 unsuccessful attempts the alarm is set. In order to secure the data transfer between sensors and devices connected to the network, the data is encrypted with AES encryption, so that the data cannot be accessed by any unauthorized user. Server authentication is secure by 3 level kerberos authentication which uses MD5 and AES for ticket generation. Server maintains log of the data transferred on the network. This log is encrypted using Blowfish algorithm. This paper presents the design and implementation of one such system, Secure Office Automation system.
