- XTS DYNAMIC ENCRYPTION KEYS FOR USE WITH XTS ENCRYPTION SYSTEMS EMPLOYING REDUCED-ROUND CIPHERS

摘要

One feature that is related to incremental ripting data to improve the data confidentiality. In one aspect, the reduced-form of the modified encryption XTS is provided for use with the block cipher rounds. Reduced - to produce the secret key in order to apply the modified round or password, or obtained in another way, the reduced-data units, the index of the data applied to the round password is ripting Inc. under the secret key. In other words, the reduced-data to be incremented by a round ripting password is not intended to be ripting Inc. under static key is ripting Inc. under dynamically varying key based on the index of the data instead. Dynamic key that if trying to derive the value of the key applied to the round password, the attacker corresponding to a particular data unit index, rather than the global static key applied to the entire address space attacker reduced by analyzing the incremental ripting data by the password only it will be obtained. Decryption procedures are also described. ;
