Wireless Data encryption and Decryption for secured communication using RF. https://www.hvstechnologies.in/product/hvs-3514-wireless-data-encryption-and-decryption-for-secured-communication-using-rf/ https://www.hvstechnologies.in/product/hvs-3514-wireless-data-encryption-and-decryption-for-secured-communication-using-rf/#respond Fri, 25 Jul 2025 11:44:10 +0000 https://www.hvstechnologies.in/?post_type=product&p=1084 Data security is primary concern for every communication system. There are many ways to provide security data that is being communicated. However what if the security assured irrespective of the hackers are from the noise. This project designing standard algorithm for encryption and decryption

 

The project aims in designing a system which is capable of providing wireless data messaging using RF technology. The modules in the project are: LAPTOP with PL2303 application to enter the data, LCD display to display the messages, Buzzer .RF modules to establish wireless communication between both systems. The communication between two sections can be possible using wireless RF network for message transmission like emergency services, breaking news, messaging, she team, helpline, ambulance & fire etc.

RF Communication ranges in between 30 KHz to 300 GHz. RF communication works by creating electromagnetic waves at a source and being able to pick up those electromagnetic waves at a particular destination. These electromagnetic waves travel through the air at near the speed of light. The wavelength of an electromagnetic signal is inversely proportional to the frequency; the higher the frequency, the shorter the wavelength.

The controlling device of the system is a PIC Microcontroller. This system consists of two Microcontrollers on either side to which Laptop with USBTTL, LCD display, RF modules are interfaced. The Microcontroller is programmed in such a way that the message typed by using pl2303 application in laptop, one system will be processed by the controller and transmitted through RF module which will be received by the RF present on other side. This received data is processed by the controller and displayed on the LCD screen along with Buzzer. The Microcontroller is programmed using Embedded ‘C’ language.

 

The main objectives of the project are:

 

  1. Design a Secured data transmission system.
  2. Wireless transmission using RF technology.
  3. Usage PL2303 application for data entry.

 

The main building blocks of the project are:

 

  • Regulated power supply.
  • PIC Microcontrollers.
  • LCD display with Driver.
  • Buzzer.
  • USB TTL.
  • Crystal Oscillator
  • RF TX, RX modules.
  • Reset
  • LED Indicators.
  • PL2303 Application.

 

Software’s used:

 

 

  1. PIC-C compiler for Embedded C programming.
  2. PIC kit 2 programmer for dumping code into Micro controller.
  3.  Express SCH for Circuit design.
  4. Proteus for hardware simulation.
