Datagram Transport Layer Security (DTLS) is a communications protocol providing security to datagram-based applications by allowing them to communicate in a way designed [1] [2] [3] to prevent eavesdropping, tampering, or message forgery.
Datagram Transport Layer Security (DTLS or Datagram TLS) 1.0 is a modification of TLS 1.1 for a packet-oriented transport layer, where packet loss and packet reordering have to be tolerated. The revision DTLS 1.2 based on TLS 1.2 was published in January 2012.
Because DTLS uses UDP or SCTP rather than TCP, it avoids the TCP meltdown problem, [9] [10] when being used to create a VPN tunnel. The original 2006 release of DTLS version 1.0 was not a standalone document. It was given as a series of deltas to TLS 1.1. [11] Similarly the follow-up 2012 release of DTLS is a delta to TLS 1.2.

GnuTLS (/ ˈ ɡ n uː ˌ t iː ˌ ɛ l ˈ ɛ s /, the GNU Transport Layer Security Library) is a free software implementation of the TLS, SSL and DTLS protocols. It offers an application programming interface (API) for applications to enable secure communication over the network transport layer, as well as interfaces to access X.509, PKCS #12, OpenPGP and other structures.
A senior FEMA official instructed subordinates to freeze funding for grant programs, hours after a judge ordered the Trump administration to stop such pauses.
Some government webpages briefly went dark Friday after federal agencies were told to comply with a White House order on removing certain language pertaining to diversity, equity and inclusion.
Some of the code for these features was later removed, including Kerberos, US-Export ciphers, TLS compression, DTLS heartbeat, SSL v2 and SSL v3. Later versions disabled more features: 2.1.1: Following the discovery of the POODLE vulnerability in the legacy SSL 3.0 protocol, LibreSSL now disables the use of SSL 3.0 by default. [55]
