Embodiment Construction
[0040] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0041] The invention combines the plaintext algorithm that can perform accurate subgraph retrieval in the atlas database and the order-preserving encryption of light-weight encryption primitives, so that the proposed invention can solve the limitations of the previous work while taking into account the correctness and security without affecting the plaintext The query complexity of the algorithm.
[0042] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0043] Such as figure 1 As shown, the ciphertext-based subgraph retrieval method prov...
