Cryptography and system security

Cryptographic techniques
Unauthorized access: Cryptography helps prevent unauthorized access to sensitive data and information by encrypting it so that it can only be accessed by those who have the appropriate decryption key.
Data breaches: Cryptography can help protect against data breaches by encrypting data at rest and in transit..
Cryptography algorithms
System security describes the controls and safeguards that an organization takes to ensure its networks and resources are safe from downtime, interference or malicious intrusion.
If data security is meant to protect the information in the books in the library, then system security is what protects the library itself..
Features of cryptography
There are three types of cryptography:
Symmetric key cryptography.Asymmetric key cryptography.Hash Function..
How cryptography works in security?
Definition.
Cryptography provides for secure communication in the presence of malicious third-parties—known as adversaries.
Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext)..
What are cryptographic techniques for security?
Cryptographic techniques include encryption, which involves applying a procedure called an algorithm to plain text to turn it into something that will appear to be gibberish to anyone who doesn't have the key to decrypt it..
What is cryptology in computer security?
Cryptology is the science of secure communications.
Cryptography creates messages with hidden meaning; cryptanalysis is the science of breaking those encrypted messages to recover their meaning..
What is system cryptography?
The term cryptosystem is shorthand for "cryptographic system" and refers to a computer system that employs cryptography, a method of protecting information and communications with codes so only those for whom the information is intended can read and process it..
What is the cryptography method of security?
A cryptography algorithm is a method of encryption and decryption that uses a mathematical formula to convert plain text into cipher text and back again.
The cryptography encryption algorithm is a type of cipher used for data confidentiality and integrity in a computer system..
What is the use of system security cryptography?
Provides cryptographic services, including secure encoding and decoding of data, as well as many other operations, such as hashing, random number generation, and message authentication..

Cryptography ensures confidentiality by encrypting sent messages using an algorithm with a key only known to the sender and recipient. A common example of this is the messaging tool WhatsApp, which encrypts conversations between people to ensure they cannot be hacked or intercepted.

Random data used as an additional input to a hash function

In cryptography, a salt is random data fed as an additional input to a one-way function that hashes data, a password or passphrase.
Salting helps defend against attacks that use precomputed tables, by vastly growing the size of table needed for a successful attack.
It also helps protect passwords that occur multiple times in a database, as a new salt is used for each password instance.
Additionally, salting does not place any burden on users.

In cryptography, snake oil is any cryptographic method or product considered to be bogus or fraudulent.
The name derives from snake oil, one type of patent medicine widely available in 19th century United States.

Term applied to cryptographic systems that are highly resistant to cryptanalysis

Strong cryptography or cryptographically strong are general terms used to designate the cryptographic algorithms that, when used correctly, provide a very high level of protection against any eavesdropper, including the government agencies.
There is no precise definition of the boundary line between the strong cryptography and (breakable) weak cryptography, as this border constantly shifts due to improvements in hardware and cryptanalysis techniques.
These improvements eventually place the capabilities once available only to the NSA within the reach of a skilled individual, so in practice there are only two levels of cryptographic security, cryptography that will stop your kid sister from reading your files, and cryptography that will stop major governments from reading your files.
