What is Data Encryption?
Data Encryption is the act of converting data from one form to another, or a cryptographic key so that only people with access to the secret key (also known as the decryption key) or password can read it. The encrypted data is often called the ciphertext, while the unencrypted data is the plaintext. Currently, encryption is one of the most popular and effective data security methods used by organizations and businesses. There are two main types of data encryption – asymmetric encryption, also known as public key encryption and symmetric encryption.
Main Uses of Data Encryption:
The purpose of data encryption is to secure digital data because it is stored on computer systems and transmitted over the internet or other computer networks. The popular Data Encryption Standard (DES) has been replaced by modern encryption algorithms that play a key role in the security of IT and communications systems.
These algorithms provide confidentiality and leverage critical security solutions including authentication, integrity, and non-denial. Authentication allows for verification of the origin of the message, and integrity provides evidence that the content of the message has not changed since it was sent. Also, do not undo a guarantee that the sender of the message cannot decline sending the message.
Data Encryption process:
The data, or plaintext, is encrypted using an encryption algorithm and an encryption key. The process results in the encrypted data, which can only be viewed in its original form if it is decoded with the correct key.
A symmetric-key uses the same secret key to encrypt and decrypt messages or files. Although symmetric encryption is processed much faster than asymmetric encryption, the sender must exchange the key with the receiver before he can decrypt it. It is therefore annoying for companies to need to securely distribute and manage large numbers of keys. So most data encryption services have tuned and use asymmetric algorithms to exchange the secret key after using the symmetric algorithm to encrypt the data.
Asymmetric encryption, on the other hand, is sometimes referred to as public key cryptography, using two different keys, a public key and a secret key. The public key can be shared with everyone, but the private key must be protected. The Rivest-Sharmir-Adeld (RSA) algorithm is a cryptographic system for public key encryption widely used to secure sensitive data, especially when it is sent over an insecure network like the internet . The RSA algorithm is widely used because both the public key and the private key can encrypt messages to ensure the confidentiality, integrity, authenticity, and irrevocability of electronic and data communications. data through the use of digital signatures.
Data Encryption solutions:
Data protection solutions that use data encryption can provide encryption for devices, email, and the data itself. In many cases, these encryption functions are also used by the controls for devices, email and data. Companies and Organizations face the challenge of data protection and preventing data loss as employees use personal devices, removable storage drives and web applications more frequently as part of their daily business processes. Sensitive data may no longer be under the control and protection of the Company when employees copy data to mobile devices or upload it to the cloud. Therefore, data loss prevention solutions can prevent data theft and the spread of malware from mobile devices as well as web and cloud applications. To do so, they must also ensure that devices and applications are used correctly and that data is secured with automatic encryption even after it is sent out of the Organization.
Although data encryption may seem like a difficult and complex process, data loss prevention solutions reliably handle this work on a daily basis. Data encryption is not something that organizations and enterprises can deal with easily, instead should choose solutions that support encryption of data with devices, emails, etc. to make sure your data is safe.
