It specifies how a TLS handshake establishes the initial security context for an SCTP association and how subsequent TLS handshakes provide key updates and re-authentication. The goal is to enable authenticated and confidential communication over SCTP using the DTLS Chunk, leveraging standardized TLS 1.3 features for key management and rekeying.}, }
