Information leakage is becoming an increasingly serious problem. When malicious users impersonate a target demodulator, the existing optical communication systems are prone to exposing the data to unauthorized users. Therefore, in the context of optical communication systems, combined with blockchain technology, SM2 and SM3 algorithms are used to encrypt data before transmission. Smart contracts on the chain effectively ensure that data is not forged, while digital signature algorithms enable user identity concealment. The results show that the encrypted data is successfully converted into a binary sequence for transmission, and the original data can be correctly recovered in the blockchain after modulation and demodulation, which improves the reliability and confidentiality of the data transmission process.

A quantum computer can be defined as a computer that implements high-speed calculations by actively utilizing the unique physical states of quantum mechanics. The unique physical states include superposition and quantum entanglement. Quantum computing takes advantage of these states to achieve greater computational power than traditional computing. One important application of quantum computing is quantum teleportation, which enables the transmission of a quantum bit (qubit) between communication entities using measurement-based calculations. However, since the transmission of measured data still relies on traditional communication channels, there can be a security issue, which could pose a potential obstacle to the widespread use of quantum teleportation in the future. In our paper, we propose enhancing the security of legacy quantum teleportation protocol by incorporating blockchain technology.
