Hybrid Approach for Providing Security by Using Quantum and Elliptic Curve Cryptography

ABSTRACT Cryptography is the best way to provide security to unprotected storage of data. In this paper providing more security by using two techniques 1. Elliptic Curve Cryptography 2.Quantum key. Elliptic curve cryptography (ECC) is a modern type of public-key cryptography wherein the encryption key is made public, whereas the decryption key is kept private. Quantum key generation (BB84 Protocol) is used to generate a strong key for encryption of the data. In existing system key of the ECC is generated randomly within the range of prime number N. In proposed Quantum Elliptic Curve QECC algorithm the Key for the Elliptic curve cryptography is generated by the Quantum key distribution algorithm. If the key is not within the range of prime number N then it can regenerate the key value by using BB84 protocol until it accepts by the ECC. By combining this two algorithms security of the data is more increased by the Quantum Elliptic Curve Encryption algorithm. Keywords: Quantum Key, Elliptic Cryptography
