What is the difference between data transit protocols

What is the difference between data transit protocols (e.g. TLS, SSL), and encryption algorithms/ciphers (e.g. AES)? How does key length affect security and processing requirements of encryption algorithms? Why do cloud services providers continue to support simpler, shorter key length ciphers as seen in protocols such as TLS 1.0/1.1? 3 pages M4 2. Write a short paper of 2-3 pages discussing the advantages of three common multi-factor authentication solutions (e.g. Duo, Yubi, Okta, RSA, Gemalto). M5 3.
