cryptographic algorithms operate faster than cryptographic algorithms when using the same length key. James recently received a secret message from Martha containing an order for custom services. He would like to be able to prove that Martha sent the message and that it could not be forged. What cryptographic goal is James attempting to achieve? a. Confidentiality b. Nonrepudiation c. Security through obscurity d. Integrity e. Authentication
