Digital Lock Based on Arduino Uno and Android Encrypted a Combination of the Vigenère and Xor Algorithm

Introduction

In today's digital era, the security of data communication is a crucial issue, especially in the use of digital locks. Many digital locks are integrated with Android smartphones through a Bluetooth connection because of its operational ease. However, without adequate protection of orders and passwords, the security of digital locking is vulnerable. To overcome this problem, the application of a combination of cryptographic algorithms is a must. One effective combination is to use Vigenère Cipher and Xor Cipher. Both of these algorithms are symmetrical cryptographic algorithms that have advantages in an efficient calculation time, so that plaintext processing can be done quickly.

The Importance of Secure Digital Locks

Digital locks are widely used in various applications, including homes, offices, and public places. With the increasing use of digital locks, the need for secure communication between devices has become a pressing issue. A digital lock that is not secure can be easily hacked, compromising the security of the entire system. This is where the combination of Vigenère Cipher and Xor Cipher comes into play. By using these two algorithms, we can create a secure digital lock that is resistant to hacking and ensures the confidentiality of communication between devices.

Arduino and Bluetooth Interface

To apply the concept of a combination of cryptographic algorithms above, a digital locking prototype is needed. Arduino Uno is an optimal choice of microcontroller for the development of electronic devices. After being connected to the Bluetooth module, Arduino Uno can communicate with other devices such as Android smartphones. Through special applications on smartphones, users can control the digital lock directly. The Arduino Uno board is a popular choice among hobbyists and professionals due to its ease of use and flexibility. It can be programmed using the Arduino IDE, which provides a user-friendly interface for writing code.

The Vigenère Cipher Algorithm

The Vigenère Cipher is a polyalphabetic substitution cipher that uses a dynamic moving key to encrypt the data. This algorithm is named after the 16th-century French cryptographer Blaise de Vigenère, who first described it. The Vigenère Cipher uses a keyword to determine the substitution of each letter in the plaintext. The keyword is repeated to match the length of the plaintext, and each letter of the plaintext is substituted with the corresponding letter of the keyword. This algorithm is considered to be one of the most secure ciphers in the world, making it an ideal choice for secure communication.

The Xor Cipher Algorithm

The Xor Cipher is a simple logic operation that is used to encrypt the data. This algorithm uses the bitwise XOR operation to encrypt the data. The Xor Cipher is a symmetric-key block cipher that uses a key to encrypt and decrypt the data. The key is used to perform the XOR operation on the plaintext, resulting in the ciphertext. The Xor Cipher is a fast and efficient algorithm that is widely used in various applications, including digital locks.

Combining the Vigenère and Xor Algorithms

By combining the Vigenère Cipher and Xor Cipher algorithms, we can create a secure digital lock that is resistant to hacking and ensures the confidentiality of communication between devices. The Vigenère Cipher provides a high level of security, while the Xor Cipher provides a fast and efficient encryption method. By combining these two algorithms, we can create a digital lock that is both secure and efficient.

Trials and Results

After testing the system repeatedly, the results show that the combination of the Vigenère and Xor algorithm can increase the confidentiality of communication between devices. This test includes various scenarios to ensure the reliability and security of the system, including sending a lock opening command and lock closure. The results show that the system is secure and efficient, making it an ideal choice for digital locks.

Conclusion

Application of the combination of the Vigenère and Xor algorithm to the Arduino Uno-based digital lock provides an efficient solution to improve the security of data communication. By integrating digital locks with an Android smartphone using the Bluetooth module, users can feel the ease and security in accessing and controlling their devices. With developing technology, further research and development of cryptographic-based security systems will be increasingly important to maintain information and information security in this digital age.
