Encryption Controls

A symmetric-key cryptosystem uses:

In RSA with p = 3 and q = 11, what are n and φ (phi)?

Which operation diffuses confusion by specifying the output position of each input bit?

How many keys does public-key cryptography use?

The Caesar cipher is an example of:

A stream cipher is based on the one-time pad, except the key is:

How many rounds does DES use?

In CBC, what does the first block use, since it has no previous block?

AES is based on which algorithm?

RSA is named after:

Encryption cannot compensate for human weakness such as sharing passwords.

A hash function uses two keys.

Substitution generates confusion.

AES is a Feistel cipher.

In public-key crypto, the public key is widely distributed and the private key is kept confidential.

RC4 is a block cipher.

Public-key cryptography relies on the modulo operation.

In RSA, ⟨e, n⟩ is the public key used for encryption.

In ECB mode, identical plaintext blocks produce identical ciphertext blocks.

A certificate authority acts as the 'DMV of the Internet' to help verify public keys.
