Systems and methods for encrypting data |
摘要 |
Data encryption techniques are presented. According to an embodiment of a method, a cryptographic hash of unencrypted data for data block X−1 is generated, and a hash of an encryption key is generated. An initialization vector for data block X is generated using the cryptographic hash and the hash of the encryption key. Data block X−1 and data block X are logically contiguous and data block X−1 logically precedes data block X. Encryption data for data block X is generated from unencrypted data for data block X using the initialization vector.
