A Record-Oriented Cryptosystem for Database Sharing
Chaung Lin, Chia‐Chan Chang, R.C.T Lee · The Computer Journal · 1992
The encryption/decryption scheme proposed in8 is generalised in this paper. The new cryptosystem presented is record-oriented, i.e. each record is encrypted integratedly with different keys and each field is decrypted individually by separate keys, and has significant advantages over many conventional methods. Compared to the encryption system proposed by Davida, Wells, and Kam,8 this new system has the advantages the previous one has and improves two drawbacks of theirs which will be stated below. Thus not only the security is increased but also the storage needed is reduced in the new cryptosystem.
