The objective of encryption is to protect data stored on a computer or network storage system. Selecting the right encryption approach for your organization In this, the data can be encrypted either with the private key or with the public key, whichever key is not used for encryption becomes the decryption key. Typically, the public key is shared publicly and is available for anyone to use, while the private key is often kept secret and is accessible only to the key owner. Symmetric encryption is frequently used for bulk data encryption since it is typically quicker and simpler to deploy than asymmetric encryption.Īsymmetric Encryption, also known as public key encryption uses two separate yet mathematically connected keys – a public key and a private key. This implies that in order to decrypt data, the sender of encrypt data must share the secret key with all the individuals who have been granted authorization. Symmetric Encryption uses the same key for both encryption and decryption. The two main methods of data encryption are Asymmetric encryption and symmetric encryption. There are several different encryption techniques, each of which was created with a particular security necessity in mind.
Authentication: verifies message authenticity.Confidentiality: encodes the content within a message.Data encryption is an essential component of a strong cybersecurity strategy, especially as more companies migrate to the cloud and become less comfortable with cloud security best practices. It is frequently necessary to comply with regulations.Įncryption plays an important role in securing many different types of information technology (IT) assets too. Since it offers data integrity, privacy, security, and authentication, encryption is something we should be concerned about. It is now an important aspect of our life in the modern world.
Encryption adds an extra layer of protection so that Information can only be accessed by those who are permitted to use it. Every time we make a purchase online, use the bank ATM, text or call somebody, encryption keeps the transaction or communication private and highly secure.
