What four basic protections can cryptography support? Cryptography can support confidentiality, integrity, authentication, and non-repudiation.

## What four basic protections can cryptography support?

Cryptography can support **confidentiality, integrity, authentication, and non-repudiation**. What four basic protections can cryptography support? Security through obscurity, or the notion that virtually any system can be made secure so long as outsiders are unaware of it or how it functions.

## Which of the following are information protections by cryptography?

**Cryptography can provide five basic information protections:**

- Confidentiality.
- Integrity.
- Availability.
- Authentication.
- Non repudiation.

## Which of the following are considered to be common asymmetric cryptographic algorithms choose all that apply?

## What are the five basic protections provided by cryptography?

The publication describes the following basic security services as **confidentiality, integrity, authentication, source authentication, authorization and non-repudiation**.

## What is the weakness of symmetric encryption?

Symmetric encryption is also called “secret key” encryption because the key must be kept secret from third parties. Strengths of this method include speed and cryptographic strength per bit of key; however, the major weakness is **that the key must be securely shared before two parties may communicate securely.**

## What are the four fundamental goals of cryptography?

More generally, it is about constructing and analyzing protocols that overcome the influence of attackers or outside people and which are related to various aspects in information security such as **data confidentiality, data integrity, authentication, and non-repudiation**.

## What is cryptography provide an example?

**Authentication and digital signatures** are a very important application of public-key cryptography. For example, if you receive a message from me that I have encrypted with my private key and you are able to decrypt it using my public key, you should feel reasonably certain that the message did in fact come from me.

## Which of the following is asymmetric cryptography?

**RSA** is an algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys.

## What characteristics are needed to consider a hashing algorithm secure?

Cryptographic hash functions are utilized in order to keep data secured by providing three fundamental safety characteristics: **pre-image resistance, second pre-image resistance, and collision resistance**.

## Which is the principle of the encryption using a key?

Which is the principle of the encryption using a key? 1. **The key indicates which funcion is used for encryption**. Thereby it is more difficult to decrypt a intercepted message as the function is unknown.

## What length SSL and TLS keys are generally considered to be strong?

**4096** is the answer.
