Since times immemorial, security of data to maintain its confidentiality, proper access control, integrity and availability has been a major issue in data communication. This paper focuses mainly on the realization of data encryption using the famous Advanced Encryption Standard Algorithm in Vb.net framework. The study is based on the development of a computer oriented encryption program, using Advanced Encryption Standard (AES) that will ensure the security of data on transit. The data encryption and decryption system described and realized in this work using AES codes is aimed at improving data security and integrity. It has been programmed, tested and proved satisfactory with all the needed modifications and upgrading.

In recent times, Wireless communication has announced its arrival on big stage and the world is going with Smartphone technology. This work describes the design and implementation of a microcontroller based messaging display system. The messaging display system will be interfaced with an android application which will then be used to display information from the comfort of one‘s phone to an LCD screen using the Bluetooth application interface. The work employs the use of an ATMEGA328p Microcontroller mounted on an Arduino board, a Bluetooth Module (HC-06) and an LCD screen. Most of these electronic display systems were using wired cable connections, the Bluetooth technology used in this work is aimed at solving the problem of wired cable connections.The microcontroller provides all the functionality of the display notices and wireless control. A desired text message from a mobile phone is s...

Encryption is one of the ways to ensure high security of images as they are used in many fields such as in secure medical imaging services, military intelligence, internet and intranet communication, e-banking etc. These images are stored or transmitted through a network; hence the security of such image data is important. In this work, recently developed encryption techniques are studied and analyzed to promote further development of more encryption methods to ensure additional security and versatility. All the techniques reviewed came into existence within the last five years (2011-2015) and are found to be useful for the present day encryption applications. Each technique is unique in its own way, which might be suitable for different applications. As time goes on, new encryption techniques are evolving. Hence, fast and secure convent...

In this work, a fuzzy logic-based simple water level indicator and controller was designed and implemented. For simplicity, the fabricated electronic level indicator defines only two (2) levels; minimum and maximum through the use of Light Emitting Diodes (LEDs). The fuzzy logic controller (FLC) was based on Mamdani type Fuzzy Inference System which has two inputs; error in level and rate of change of error with one output; valve position. The fuzzy controller was implemented in MATLAB and then simulated in Simulink to test the behavior of the system when the inputs change. The response of the fuzzy controller was then compared with a conventional PID controller for system performance check and reliability. The results obtained show that Fuzzy logic has little overshoot and steady-state error and stabilizes quickly providing accurate level control, hence can be used for rapid control with coarse adjustment. This designed controller can be tested with periodically varying liquid level tracking applications. And For better and higher accuracy, and optimized FLC by tuning the fuzzy parameters may be employed in future designs.
