Asymmetric encryption can be used for confidentiality but not for

authentication.

Plaintext is transformed into ciphertext using two keys and a

decryption algorithm.

A major advance in symmetric cryptography occurred with the

development of the rotor encryption/decryption machine.

Public-key encryption is more secure from cryptanalysis than

symmetric encryption.

Much of the theory of public-key cryptosystems is based on

number theory.

Asymmetric algorithms rely on one key for encryption and a

different but related key for decryption.

The encryption algorithm performs various transformation on the

ciphertext.

If the authenticator is encrypted with the sender's private key, it

serves as a signature that verifies origin, content, and sequencing.

A trap-door one-way function is easy to calculate in one direction

and infeasible to calculate in the other direction unless certain

additional information is known.

A public-key encryption scheme is not vulnerable to a brute-force

attack.

Before the application of the public-key cryptosystem each

participant must generate a pair of keys.

The defense against the brute-force approach for RSA is to use a

large key space.

Timing attacks are ciphertext attacks that are only applicable to

RSA.

__________ are two related keys, a public key and a private key that are used to perform complementary operations, such as encryption and decryption or signature generation and signature verification.

Public-key algorithms are based on __________.

The __________ indicates that the subscriber identified in the certificate has sole control and access to the private key.

A __________ is a cryptographic algorithm that uses two related keys, a public key, and a private key. The two keys have the property that deriving the private key from the public key is computationally infeasible.
