Introducing Quantum Cryptography Based Secured Encryption and Decryption Algorithms

With the expansion in electronic communication, the significance of cryptography is apparently increasing every year. Encryption is a cryptography technique to send unintelligible information and decryption to restore the information. These techniques usually undergo difficulty with eavesdropping of plaintext and ciphertext. The conventional cryptography is vulnerable to attacks using high computational resources. Necessarily, an elegant concept of Quantum cryptography based on laws of quantum mechanics is introduced to offer secure and private communication. This paper gives a method for encryption and decryption using Toffoli quantum gate named as VBA Quantum Encryption and Decryption Algorithms. The incorporation of gate renders security which acts as a cumbersome to eavesdropping attack. Besides, a way to detect known plaintext, ciphertext only and chosen plaintext attack through public discussion is explained.
