Org domain. org. org. 101 ; Fig. 9. An example of SPF record published to DNS 26 J. Jeong et al. Fig. 10. A barebones SIP-based VoIP service network adopting SPF (5)’ a spammer forges his return-path and directly forwards it to SIP Proxy3. (6) SIP Proxy3 extracts an IP address from “From” field of the incoming INVITE message header. Then, SIP Proxy3 asks whether the IP address belongs to one of the IP addresses registered on SPF record managed by via domain. (7) If the answer includes “fail”, SIP Proxy3 rejects the incoming message; otherwise, it accepts the message.

19, 20, 21]). Bostr¨ om and Felbinger presented a ”ping-pong” protocol (PP protocol) [22], which is intended to be a QSDC protocol, to distribute a bit message based on an EPR pair. However, an eavesdropper, Eve, may eavesdrop on information if quantum channel is imperfect (noisy or lossy), and it can also be attacked without eavesdropping [23]. It is a quasi-deterministic quantum communication protocol. The capacity is restricted since an entangled state carries only one bit message in each a protocol run.

For this reason, SIP proxies should parse “Via” header instead of “From” header from the incoming INVITE message. VoIP SPAM Response System Adopting Multi-leveled Anti-SPIT Solutions 27 Fig. 11. Processing flows of proxy server with SPF module Figure 11 describes the transactions of SIP_SPF query and response. When an INVITE message reaches the destination SIP proxy server, the proxy server checks whether the “Request URI” is same with its own URI. In step 1, if two URIs are not same, the INVITE message is relayed to the designated SIP proxy server in other domain; otherwise, the proxy server checks whether the “From URI“ is same with its own URI.
