Cybersecurity attacks are rising day by day due to the explosive growth of the internet. Many encryption techniques and authentication mechanisms also came into existence to avoid or minimize cybersecurity attacks. However, these traditional encryption algorithms are facing new challenges because of quantum computers. Due to their high computational capacity, quantum computers will be able to decipher the messages which are encrypted by the encryption algorithms. To guard against these sophisticated cyber attacks, the Quantum-Key Distribution (QKD) protocol and the Time-Released Encryption(TRE) algorithms are becoming popular. The paper proposes a Time-Based Quantum Key Distribution Protocol (TB-QKD), that enables a secure key exchange and decryption process between two trusted parties on an arbitrary time. The proposed TB-QKD protocol allows the sender and receiver to share the keys securely through the quantum channel with the help of QKD protocol. The algorithm encryption and decryption times for different messages have been observed and presented. Moreover, this protocol also provides a suitable solution that addresses many vulnerabilities that occur in the domain of data security and confidentiality.
