Securstore Online Data Backup Expert Tips: Symmetric Key Encryption for Cloud Computing
A variety of encryption algorithms have been developed to provide Cloud users with data security. These algorithms are said to support compliance, protect the user against data breach incidents, and secure information against advanced persistent threats. A few Cloud services claim to have obtained 3rd party certification on the security of the particular algorithm that they use in data encryption. Others claim that their algorithm is military-grade or bank-grade. But, what are these algorithms? How do they work?
Symmetric key algorithms use the same key for encryption and decryption. Therefore, these encryptions are also called private key encryptions. It is one of the oldest methods of encryption in use in the world today and is secure because the user must have the key to decrypt and read the data. The encryption may use a stream cipher or block cipher based on the amount of data that needs to be encrypted. Stream ciphers encrypt one character at a time, while block ciphers will encrypt block of data. Popular encryption algorithms in this category are Data Encryption standard (DES), Advanced Encryption Standard (AES), International Data encryption Algorithm (DEA) and Blowfish algorithm.
Let us look at two of the most popular symmetric key encryption algorithms in use with Cloud backup and recovery services.
