Field Documentation

kid

struct GNUNET_ShortHashCode UDPBox::kid

Key and IV identification code.

KDF applied to an acknowledged base key and a sequence number. Sequence numbers must be used monotonically increasing up to the maximum specified in struct UDPAck. Without further struct UDPAcks, the sender must fall back to sending handshakes!

gcm_tag

uint8_t UDPBox::gcm_tag[(128/8)]

128-bit authentication tag for the following encrypted message, from GCM.

MAC starts at the body_start that follows and extends until the end of the UDP payload. If the hmac is wrong, the receiver should check if the message might be a struct UdpHandshakeSignature.
