Given the limitations of current classic image encryption algorithms and the unconditional security characteristics of quantum key distribution protocols, the author proposes an image encryption method based on quantum key distribution and pixel scrambling. The author first analyzed the security issues of quantum image encryption algorithms based on image scrambling methods, namely that image scrambling methods have periodicity, which can ensure that the image can be restored after scrambling. If an image cannot be guaranteed to return to its original state after performing scrambling operations, legitimate users cannot obtain the secret information in the original image, and image scrambling loses its original meaning; However, the periodicity of image scrambling methods not only ensures that legitimate users can decrypt images, but also provides convenience for attackers to steal original image information. Secondly, it is pointed out that when evaluating and analyzing quantum image encryption algorithms, the evaluation indicators should include two parts: One is performance analysis, which is the analysis of the network complexity of quantum circuits. In quantum computing, the network complexity of quantum circuits is usually represented by the number of quantum basic logic gates. The second is security analysis, which mainly includes key analysis (including key space size and key sensitivity analysis), statistical analysis (including pixel correlation, histogram analysis, information fusion, and scatter plot distribution density analysis). Finally, experimental simulations have shown that the NPCR values of the plaintext and ciphertext images of the three images tend to 100%. The encrypted image histogram is evenly distributed, with very weak pixel correlation and high pixel change rate and information entropy.
Electric power information system is related with the safe operation of power grid. To ensure the data of electric power information will not be eavesdropped or deciphered, we need a strict way of encryption. With the improvement of computing capacity, traditional encryption algorithms are at high risk of crack. Quantum communication technology is an absolute security encryption mode, which can significantly improve the safety of electric power information system. For the particularity of electric power production and management data by analysing the principle of quantum communication technology, we have put forward implementation plan of electric power information system data encryption scheme and quantum communication network.

It uses both traditional security software encryption algorithms and classical cryptographic systems to achieve a series of operations such as secret storage, transmission and restoration of data. This paper introduces the principle of quantum key distribution and its applications from the physical level; then analyses its security problems and the corresponding research status and proposes improvement methods and measures; finally, with the goal of "bit-based computing information security", a new type of secure communication scheme is designed.
: Quantum computing is set to bring about a significant change in safe data transfer by utilising the fundamental principles of quantum physics to completely modify cryptographic systems. This analytical article explores advanced methods for securely transmitting data in quantum computing networks, with a specific focus on quantum key distribution (QKD), quantum encryption, and post-quantum cryptography. Quantum Key Distribution (QKD) is a significant breakthrough that enables two parties to generate a shared, unpredictable secret key that is exclusive to them. This key may be utilised to encode and decode communications securely. QKD, unlike traditional cryptography systems, use the properties of quantum physics, such as superposition and entanglement, to guarantee the detection of any eavesdropping attempts. This paper investigates different Quantum Key Distribution (QKD) protocols, such as BB84 and E91, by assessing their security assumptions, implementation difficulties, and practical uses. QKD's resilience against both quantum and classical attacks establishes it as a fundamental element of forthcoming secure communication infrastructures. Quantum encryption enhances the capacity for safe data transfer by employing quantum states to encode information, providing encryption systems that are theoretically impossible to crack. This study examines the progress made in quantum encryption methods, such as quantum bit commitment and quantum oblivious transmission, and emphasises their significance in improving privacy and security in quantum networks. An analysis is conducted on the incorporation of quantum encryption into current communication protocols, with a focus on the advantageous collaboration and technical challenges.

Obviously, the main way for people to get information is through the eyes to see the image. Image information hasmany advantages such as vivid, intuition, information amount large and so on.
