Single Answer
0Renee wants to ensure that her logs support nonrepudiation. What should she do to ensure this?
Answer Options
A
Encrypt, then hash the logs.
B
Hash the logs and then digitally sign them.
C
Digitally sign the log file, then encrypt it.
D
Hash, then encrypt the logs.
Correct Answer: B
Explanation
Calculating a cryptographic hash allows the log's hash to be compared against copies to validate that they match. Digitally signing the hash ensures that it can be verified to be the original. Encrypting the log does not allow it to be verified against an original. Without a digital signature, a hash does not meet Renee's requirement for nonrepudiation.
