TLS The Erlang/OTP Way

Published in ACM SIGPLAN Erlang Workshop (Erlang), 2023

The Transport Layer Security (TLS) protocol is one of the most used protocols to ensure data privacy, integrity and authenticity on the Internet. Erlang/OTP’s TLS implementation is widely used in industry, and especially in the telecommunication sector.

This paper describes an overview of the TLS protocol in the context of Erlang. We explain Erlang/OTP’s TLS protocol design and implementation, optimizations, a benchmark evaluation of the Erlang TLS protocol implementation against previous Erlang/OTP’s TLS implementations, and a benchmark comparison against the Go’s TLS implementation.
