Abstract

Here, we propose a quantum asymmetric key cryptography scheme using Grover's quantum search algorithm. In the proposed scheme, Alice generates a pair of public and private keys, keeps the private keys safe, and only discloses public keys to the outside. Bob uses Alice's public key to send a secret message to Alice and Alice uses her private key to decrypt the secret message. Furthermore, we discuss the safety of quantum asymmetric key encryption techniques based on quantum mechanical properties.

Asymmetric cryptography system uses an encryption key that consists of a public key and private key pair. Security in asymmetric key encryption systems relies on managing private keys without exposing them to the outside world. In contrast, public keys can be released to others. Anyone with a public key can create and send a secret message at any time, whereas someone with a private key can open the secret message at any time. In this figure, Bob, who shares Alice's public key P(A), encrypts the message m he wants to send to Alice, and Alice decrypts the message using her private key S(A).
