| Is there any way to use UDP for private, authenticated messages? Suppose your use case is like statsd, where you can tolerate the occasional lost message, and you don't want to block on network activity--you just want to fire off the message and keep going--but you do want your messages encrypted, and you want to make sure the receiver can trust the message is from you. Someone else should not be able to replay your message and have the receiver accept it. An attacker should not be able to break the encryption after sniffing n messages. Is there any existing protocol that provides such a blend of features? I've seen DTLS, which is close, but has poor support on Windows and in scripting languages. Is there anything else out there? Thanks HN! |
