What is the primary focus of differential cryptanalysis?

Analyzing the frequency of characters in ciphertext

Exploiting physical characteristics of the system

Analyzing how differences in input affect differences in output

An organization needs to securely exchange a large volume of data with a partner. They plan to use a hybrid cryptosystem. Which sequence of operations correctly establishes a secure channel?

Encrypt the data with the partner's public key and send the private key separately via courier.

Encrypt the data with a symmetric key and send the key in plaintext along with the data.

Use the partner's private key to encrypt the data and send it over the internet.

Generate a symmetric session key, encrypt the data with that key, and encrypt the session key with the partner's public key.

How do audit trails support non-repudiation in cryptographic operations?

By encrypting all data to prevent unauthorized access

By using digital signatures on every file

By storing private keys in a secure location

By recording cryptographic events and actions with timestamps and user identities
