Questions and Answers
Which type of cryptography should Company E use to securely store passwords for its users?
Which type of cryptography should Sarah use to prove that she sent a message at a certain time without revealing the contents of the message?
Which type of cryptography should Company F use to ensure that its encrypted data remains secure even if an attacker gains access to its encryption keys?
Study Notes
Cryptography Scenarios
- To securely store passwords, Company E should use Hashing, a one-way encryption technique that transforms passwords into a fixed-length string of characters, making it difficult to reverse-engineer the original password.
Digital Signatures
- To prove that she sent a message at a certain time without revealing the contents of the message, Sarah should use Digital Signatures, which use asymmetric cryptography to authenticate the sender and prove the integrity of the message.
Key Management
- To ensure that its encrypted data remains secure even if an attacker gains access to its encryption keys, Company F should use Asymmetric Cryptography, which involves the use of a pair of keys: a public key for encryption and a private key for decryption, providing an additional layer of security.
