This podcast collectively explore various facets of TLS (Transport Layer Security) and its underlying cryptographic principles, including cipher suites, key exchange algorithms, and the evolution from SSL. Several sources discuss the importance and management of TLS certificates and the role of Certificate Authorities (CAs) within the Public Key Infrastructure (PKI) for secure online transactions and authentication. Additionally, one paper examines oblivious transfer (OT) protocols and garbled circuits as cryptographic techniques for secure two-party computation with privacy considerations. Finally, a NIST publication offers guidelines for TLS implementations and the management of TLS server certificates in enterprise environments, highlighting security risks and recommending best practices, including automation.
