How does it affect performance and security

Assignment Help Computer Network Security
Reference no: EM13332890

Sector level hard disk encryption is one of the most interesting problems of all. Assume that AES-128 is used to encrypt your local hard disk. What mode will you use? CBC or ECB? (See sections 5.5.1 and 5.5.2) Or any other you can propose? How does it affect performance and security? Hints: when you try to read/write block n on the hard disk, do you need to read/write other blocks? You discussion may also briefly address the firmware password protection of HDD.
