It converts data from a readable, plaintext format into an unreadable, encoded format cipher text. Users and processes can only read and process encrypted data after it is decrypted. The decryption key is secret, so it must be protected against unauthorized access.
Furthermore, encryption is the process of converting data into an unusable form and do not stop hacking or data theft. Instead, it prevents stolen content from being used, since the hacker or thief cannot see it in plaintext format.
When information or data is shared over the , it goes through a series of network devices worldwide, which form part of the public internet. As data travels through the public internet.
Moreover, there is a chance it could be compromised or stolen by hackers. To prevent this, users can install specific software or hardware to ensure the secure transfer of data or information.
The key used to encode is the same as the one used to decode, making it best for individual users and closed systems. Otherwise, the key must be sent to the receiver.
However, this increases the risk of compromise if it’s intercepted by a third party, such as a hacker. This method is faster than the asymmetric method.
1. Indention and Authenticity
The keys are essentially large numbers that have been paired with each other but are not identical, Machine Learning hence the term asymmetric.
Furthermore, the private key is kept secret by the owner, and the public key is either shared amongst authorized recipients or made available to the public at large.
2. DES encryption
It stands for Data Encryption Standard. This is a now-outdated symmetric encryption algorithm not considered suitable for today’s uses.
Therefore, other encryption algorithms have succeeded DES.
3. 3DES encryption
And it stands for Triple Data Encryption Standard. This is a symmetric key algorithm, and the word triple is used because data is passed through the original DES algorithm three times during the encryption process.
Moreover, triple DES is being slowly phased out but still manages to make a dependable hardware encryption solution for financial services and other industries.
4. Data encryption in transit
It is considered in transit when moving between devices, such as within private networks or over the internet. During the transfer, data is at greater risk because of the need for decryption before transfer.
However, the vulnerabilities of the transfer method itself. Encrypting data during transfer, referred to as end-to-end encryption, ensures that even if the data is intercepted, its privacy is protected.
5. Data encryption at rest
Data is considered at rest when it sits on a storage device and is not actively being used or transferred. Data at rest is often less vulnerable than when in transit since device security features restrict access.
6. Encryption protects data across devices
Most of us use multiple devices in our day-to-day lives, and transferring data from device to device can carry risks. Encryption technology helps protect data across devices, during transfer.
However, Additional security measures like advanced authentication help to deter unauthorized users.
7. Symmetric encryption
It uses a single, private key for encryption and decryption. It is a faster method than asymmetric encryption and is best used by individuals or within closed systems. Using symmetric methods with multiple users in open systems.
However, a network requires the transmission of the key and creates an opportunity for theft. The most commonly used type of symmetric encryption is AES.
8. Asymmetric encryption
It uses paired public and private keys that are mathematically linked and can only be used together. Either key can be used to encrypt data but the paired key must be used to decrypt it.
9. Approaches toward Encryption
Asymmetric encryption is used by multiple users and across open networks, like the Internet, because the public key can be freely shared without risking data theft. The most commonly used types of asymmetric encryption are ElGamal, RSA, DSA, and PKCS.
10. Data Encryption in Transit
It is considered in transit when it is moving between devices, such as within private networks, through the Internet, or from a laptop to a thumb drive. Data is at greater risk during transfer due to the need for decryption before transfer.
Moreover, the vulnerabilities of the transfer method itself. Encrypting data during transfer, referred to as end-to-end encryption, ensures that even if the data is intercepted, its privacy is protected.
