By 1999, its successor – the Transport Layer Security (TLS) protocol – offered a more robust cryptographic protocol across technical components like cipher suites, record protocol, message authentication , and handshake process. By 2001, the NIST dubbed it the Advanced Encryption Standard (AES) and officially replaced the use of DES.
