Abstract:
A system () for securing a database including a first and second tables is provided, where the first table includes a first key field and a first data field and the second table includes a second key field and a second data field. The first and second key fields specifying first and second key field entries having one common entry. The system () can replace the first key field entries with first adjusted key field entries based on first initialization vectors. The system () also replaces the second key field entries with second adjusted key field entries based on second initialization vectors different from the first initialization vectors. The system further encodes the first and the second adjusted key field entries based on index keys to generate an encrypted database. In the encrypted database, a value of the common entries in the first and second tables are different.
