Research and realization of multi-level encryption method for database

Abstract: Multi-level encryption method was used to encrypt the database system and encryption design method for different levels of data granularity was given, respectively taking database level, table level, recording level and field level as the objects.

Method and system for database encryption

Abstract: The present disclosure is directed to a method for database encryption, which includes maintaining a database having fields and storing one or more data elements in a location associated with an IP address, wherein the IP address is 128 bits or greater and wherein the location of the IP address is remote from the location at which the database is maintained. The method may include storing, in at least one field of the database, a reference including an IP address corresponding with at least one of the data elements. In addition, the method may include retrieving the reference responsive to a request received from a user. Further, the method may include engaging a security layer around the data element, including performing at least one security check according to a security protocol, and determining whether to grant access to the at least one data element based on the security protocol.

Ciphertext indexing method for database encryption and in-base encryption system

Abstract: The invention relates to a ciphertext indexing method for database encrypted fields and an in-base encryption system and belongs to the field of information security technology According to the method, first, identification ID is mapped to encryption ID based on an encrypted field P1, (encryption ID, Hash value) is saved into a T2(ID2, P2), finally, a ciphertext index table T2 is established, and the table where the encrypted field P1 exists is recorded as T1, wherein the table T2 comprises a ciphertext index field P2, and fields ID2 in one-to-one correspondence with records in the T1 are recorded in the T2; and then, content of a to-be-encrypted field is mapped to the Hash value based on an order-preserving Hash function, equivalent query and range query of the encrypted field are realized based on the Hash value obtained after the record of the content of the to-be-encrypted field is mapped to the Hash value based on an encryption function, decryption is performed on the recorded ID2 according to query results to obtain a record set in the T1, and the record set is returned Compared with the prior art, the method is good in reliability and high in universality, meanwhile has high security and can guarantee extremely high retrieval and storage efficiency

Research and Implementation of Database Encryption System

Abstract: An effective method to realize database information security is to use MiddlewareThe design integrates the identity verification,access control,encrypted transmission and data encryption in the network encrypted Data Base Safety Middleware(DBSM),which providing the safe access service of the database information to ensure data confidentiality,integrity and availabilityConsequently,the legal rights and interests of the owners and users are guaranteed
