An encryption algorithm is a mathematical procedure used to encrypt data. Through the use of an algorithm and a key, information is encoded into cipher text and requires the use of a key to transform the data back into its original form.
Algorithms are an essential part of a technology to ensure effective and secure authentication, as well as to provide integrity and encryption. ETSI creates cryptographic algorithms and protocols specific to fraud prevention, unauthorized access to public and private telecommunications networks and user data privacy.
ETSI is custodian of these algorithms, as well as algorithms produced by other organizations. We are also custodians of other codes and test suites.
