Notes - Computer Security MT24, Asymmetric key ciphers
Flashcards
@Define intuitively a trapdoor function.
A function that is easy to perform and difficult to invert, but easy to invert given some extra information.
What is the difference between the public key and the private key?
- Public key: Published publically, used for encryption
- Private key: Kept secret, used for decryption
Why is a chosen plaintext attack always possible against an asymmetric key cipher?
An attacker can use the public key to encrypt as many plaintexts as they want.
