AESĪdvanced Encryption Standard (AES) is the most popular and broadly used symmetric encryption standard today. Typical applications using the algorithm are Mozilla Firefox and MS Office. Such types of encryption algorithms are used to encrypt ATM pins and UNIX passwords. In triple DES, three keys are used for encryption, and each of the keys comprises 56 bits. The cypher algorithm used in triple DES is 3 times for each data block. It is an advanced form of the Data Encryption Standard method wherein each information block comprises 64-bit data. Triple DES (Data Encryption Standard) is a symmetric type of encryption technology. The commonly used encryption algorithms are: Triple DES However, the data is recovered back into plaintext employing the decryption key. An encryption algorithm uses an encryption key to modify the data to look random. The encryption algorithm in data encryption is used to change data/information into ciphertext. On the other hand, the private key is used to decrypt the data and is available to the receiving party only. The public key is used for the encryption of data and is communicated publicly to be used by anyone. In this type of encryption, there are two types of encryption keys: public and private. This type of encryption is useful for closed systems, where there is negligible risk of third-party intrusion. That is, both the sender and receiver use that same key for any type of communication. The encryption and decryption keys are the same in the symmetric type of encryption.

Two major types of data encryption are symmetric and asymmetric encryption. What are the Major Types of Data Encryption Techniques? At the receiver end, the ciphertext can be read in its original form once decoded using the correct decryption key.Further, the ciphertext is transmitted over the communication channels.Applying the suitable algorithm and encryption key, the plaintext is transformed into a ‘ ciphertext‘ (an encrypted piece of information).There are numerous encryption algorithms to be used, varying based on the application and security requirement.The plaintext data is then encrypted using different encryption techniques, mathematical calculations, and an encryption key.The data or information to be encrypted is called plaintext or cleartext.Having read about what data encryption is, it’s time to understand how data encryption works. With the elevated need for cyber security due to the risk of cybercrime, it’s becoming very important for an organisation to be familiar with basic encryption working and related terms.

Simply saying, data encryption converts readable data into an unreadable format to maintain the confidentiality of data during the transition. This ensures the confidentiality of the information.ĭata encryption is defined as the process of safeguarding data from cyber threats by encoding it in a way, which can only be interpreted with the correct encryption key. What Is Data Encryption and How Does it Work?Įncryption is the process where complex algorithms are applied to encrypt messages, data, or files such that they can be read only by authorised persons. This article will explain what data encryption is and the different techniques, algorithms, and types of data encryption methods.
