What common method is used to ensure that security and integrity of a root CA?
“What common method is used to ensure the security and integrity of a root CA? –
Keep it in an offline state from the network

Why is IPsec considered to be a transparent security protocol quizlet?
Why is IPsec considered to be a transparent security protocol?
IPsec is designed to not require modifications of programs, or additional training, or additional client setup
. At what stage can a certificate no longer be used for any type of authentication?
What protocol developed by Netscape in 1994 is designed?
Cybersecurity History: Read about how Netscape began development of
the SSL protocol
. In 1994, Netscape had SSL version 1.0 ready, but it never made a public debut as it had several significant security flaws, which eventually led to the evolution of HTTPS based on SSL 2.0 and its successor TLS.
What length SSL and TLS keys are generally considered to be strong?
4096
is the answer.
Why are longer keys better than shorter keys?
The effect of key length on performance is most readily apparent in something like RSA, where modular exponentiation takes about O(nk) time for n-bit numbers (k>2 depends on the algorithm). Longer keys usually
mean longer key schedules
, which may be more difficult to analyze, require more constants and code, etc.
What is used to create session key?
A MEK
is an encryption key that protects other encryption keys. A cryptographic key used to generate a large number of other keys, a master key is usually not directly used for encryption or decryption. Rather, it is used to generate session keys that are then used for communications.
What is a digital certificate group of answer choices?
A digital certificate is
a technology used to associate a user’s identity to a private key
.

message confidentiality, message integrity and traffic analysis protection
.
What alternative term can be used to describe asymmetric cryptographic algorithms answer choices?
Asymmetric cryptographic algorithms are also known as
private key cryptography

What two individuals trust each other because of the trust that exists?
| Term Definition | third-party trust A trust model in which two individuals trust each other because each individually trusts a third-party | Transport Layer Security (TLS) A protocol that is more secure than SSL and guarantees privacy and data integrity between applications |

What is a block cipher algorithm that operates on 64 bit blocks and can have a key length from 32 to 448 bits?
| Term Definition | Asymmetric Cryptographic Algorithm Cryptography that uses two mathematically related keys | Block Cipher A cipher that manipulates an entire block of plaintext at one time | Blowfish A block cipher that operates on 64-bit blocks and can have a key length from 32 to 448 bits |

How does PKI used for email encryption?
PKI performs
encryption directly through the keys that it generates
. It works by using two different cryptographic keys: a public key and a private key. Whether these keys are public or private, they encrypt and decrypt secure data.
