Question:
Which of the following is not an asymmetric system? +SSL +DES +PGP +RSA
Answer:
DES The Data Encryption Standard is a symmetric-key algorithm for the encryption of electronic
data. Although now considered insecure, it was highly influential in the advancement of modern
cryptography.
Question:
In order for User A to send User B an encrypted message that only User B can read, User A must
encrypt message with which of the following keys? +User B's public key +User B's private key
+User A's public key +User A's private key
Answer:
USER B's Public Key Public key cryptography, or asymmetrical cryptography, is any cryptographic
system that uses pairs of keys: public keys which may be disseminated widely, and private keys
which are known only to the owner
Question:
Which of the following is generally true about block sizes? +Block size is irrelevant to security
+Block sizes must be more than 256 bits to be secure +Larger block sizes increase security +Smaller
block sizes increase security
Answer:
Larger Block sizes increase security Larger block sizes do increase security, however at the cost of
processing power and encryption time.
Question:
, A _____ is a function that takes a variable-size input m and returns a fixed-size string. +Hash
+Symmetric cipher +Feistel +Asymmetric cipher
Answer:
Hash A hash function is any function that can be used to map data of arbitrary size to data of fixed
size. The values returned by a hash function are called hash values, hash codes, digests, or simply
hashes.
Question:
Which of the following is a cryptographic protocol that allows two parties to establish a shared key
over an insecure channel? +Elliptic Curve +MD5 +RSA +Diffie-Hellman
Answer:
Diffie-Hellman Diffie-Hellman key exchange is a method of securely exchanging cryptographic
keys over a public channel and was one of the first public- key protocols as originally
conceptualized by Ralph Merkle and named after Whitfield Diffie and Martin Hellman. DH is one
of the earliest practical examples of public key exchange implemented within the field of
cryptography.
Question:
A _________ is a digital representation of information that identifies you as a relevant entity by a
trusted third party? +Ownership stamp +Digest +Digital Signature +Hash
Answer:
Digital Signature A digital signature is a mathematical scheme for demonstrating the authenticity of
digital messages or documents
Question:
What is the standard used by most digital certificates? +RFC 2298 +OCSP +X.509 +CRL
Answer:
x.509 In cryptography, X.509 is a standard that defines the format of public key certificates.
