At present,uploading data to public servers or cloud platforms has become the mainstream method for data management.However,this practice has serious risks of confidential data leakage and privacy leakage.In order to solve this problem and protect data security and user privacy,we propose a secure and efficient searchable symmetric encryption scheme for consumables data,which provides effective data protection and user privacy protection measures in the consumable material management system.Searchable symmetric en-cryption is an advanced technology that can realize search in ciphertext state,which allows searching in encrypted data sets without decryption.The proposed scheme uses the KECCAK256 hash algorithm and AES encryption algorithm to process data of consumable material management,and introduces an inverted index structure and random operation to realize the ciphertext search function.This structure can effectively support fast search,and can prevent the plaintext information from being inferred from the index,thereby improving the privacy protection level of the data.Experimental results show that compared with some known such algorithms,the proposed scheme performs well in terms of security and search efficiency,providing a reliable and efficient data privacy protection measure for the consumables management system.
