The Classification of Quantum Symmetric-Key Encryption Protocols
This work provides a foundational classification for researchers in quantum cryptography, but it is incremental as it builds on existing protocol analysis without introducing new methods.
The paper tackled the classification of quantum symmetric-key encryption protocols by analyzing five elements, resulting in 32 categories where 5 are feasible, 21 are impossible, and 6 remain unconstructed, narrowing future research to 5 kinds.
The classification of quantum symmetric-key encryption protocol is presented. According to five elements of a quantum symmetric-key encryption protocol: plaintext, ciphertext, key, encryption algorithm and decryption algorithm, there are 32 different kinds of them. Among them, 5 kinds of protocols have already been constructed and studied, and 21 kinds of them are proved to be impossible to construct, the last 6 kinds of them are not yet presented effectively. That means the research on quantum symmetric-key encryption protocol only needs to consider with 5 kinds of them nowadays.
