    Appendix F Guide to Encrypting and Decrypting Data The encryption method used by SecureHead is called Cipher-block Chaining (CBC). With this method, each block of data is XOR’ed with the previous data block before being encrypted. The encryption of each block depends on all the previous blocks. As a result, each encrypted data block would need to be decrypted sequentially.
