Three-key DES (3DES), in particular, does not meet the National Institute of Standards and Technology (NIST) and Payment Card Industry Data Security Standard (PCI-DSS) requirements. It was found weak and insufficient to address the higher processing power requirements of most modern computers. Data Encryption Standardĭata Encryption Standard (DES) used to be the standardized method for encrypting various modes of electronic communications but was soon phased out. Some of the symmetric algorithms available are: 1. The key can be a code or random string of letters, numbers, and symbols generated by a random number generator (RNG). Symmetric encryption uses algorithms to convert data into a form that can only be understood by those who have access to the secret key. Read More about “ Symmetric Encryption ” What Are the Common Symmetric Encryption Algorithms? Anyone who has it can unlock and access the vault’s contents. Think of symmetric encryption as the combination to an office vault. As a result, even users who may no longer be part of the company can intercept and read encrypted data. And that sometimes leads organizations to forget to change them. A key in symmetric encryption can be used forever. Many organizations use symmetric encryption because it is relatively inexpensive. The key can be a word a phrase or a nonsensical or random string of letters, numbers, and symbols. The sender and recipient share the key or password to gain access to the information. Symmetric encryption is a means of protecting data using a secret key to encrypt (lock) and decrypt (unlock) it.
