THANKS This is an indicator that a ZOO is about to terminate the connection.8.2. CRITIC Responses SIGH <insult> When the ZOO establishes a connection, the CRITIC must respond with a SIGH and an optional insult. IMPRESS_ME A CRITIC must respond with an IMPRESS_ME once a ZOO has made a TRANSCRIPT request. REJECT <code> REJECT 0 <text> When a transcript has been received, the CRITIC must respond with a REJECT and a code that indicates the reason for rejection. A table of rejection codes is provided below. When the code is 0, the CRITIC may respond using free text. A CRITIC may send a REJECT before it has received or processed the full text of the transcript. DONT_CALL_US_WE'LL_CALL_YOU The CRITIC makes this statement before terminating the connection.Christey Informational [Page 14] RFC 2795 The Infinite Monkey Protocol Suite (IMPS) 1 April 2000 GRUDGING_ACCEPTANCE THIS RESPONSE IS NOT SUPPORTED IN THIS VERSION OF PAN. The Working group for the Infinite Monkey Protocol Suite (WIMPS) agreed that it is highly unlikely that a CRITIC will ever use this response when a REJECT is available. It is only included as an explanation to implementors who do not fully understand how CRITICs work. In time, it is possible that a CRITIC may evolve (in much the same way that a monkey might). Should such a time ever come, the WIMPS may decide to support this response in later versions of PAN.8.3. Table of CRITIC Reject Codes CODE DESCRIPTION ------------------------------------------------------------------- | 0 | <Encrypted response following; see below> ------------------------------------------------------------------- | 1 | "You're reinventing the wheel." ------------------------------------------------------------------- | 2 | "This will never, ever sell." ------------------------------------------------------------------- | 3 | "Huh? I don't understand this at all." ------------------------------------------------------------------- | 4 | "You forgot one little obscure reference from twenty years | | ago that renders your whole idea null and void." ------------------------------------------------------------------- | 5 | "Due to the number of submissions, we could not accept every | | transcript." ------------------------------------------------------------------- | 6 | "There aren't enough charts and graphs. Where is the color?" ------------------------------------------------------------------- | 7 | "I'm cranky and decided to take it out on you." ------------------------------------------------------------------- | 8 | "This is not in within the scope of what we are looking for." ------------------------------------------------------------------- | 9 | "This is too derivative." ------------------------------------------------------------------- |10 | "Your submission was received after the deadline. Try again | | next year." ------------------------------------------------------------------- If the CRITIC uses a reject code of 0, then the textual response must use an encryption scheme that is selected by the CRITIC. Since the PAN protocol does not specify how a ZOO may determine what scheme is being used, the ZOO might not be able to understand the CRITIC's response.Christey Informational [Page 15] RFC 2795 The Infinite Monkey Protocol Suite (IMPS) 1 April 20008.4. Example ZOO-to-CRITIC Session using PAN Below is a sample session from a ZOO (SanDiego) to a CRITIC (NoBrainer). NoBrainer> SIGH Abandon hope all who enter here SanDiego> COMPLIMENT We love your work. Your words are like SanDiego> COMPLIMENT jewels and you are always correct. SanDiego> TRANSCRIPT RomeoAndJuliet.BoBo.763 251 NoBrainer> IMPRESS_ME SanDiego> Two households, both alike in dignity, SanDiego> In fair Verona, where we lay our scene, SanDiego> From ancient grudge break to new mutiny, SanDiego> Where civil blood makes civil hands unclean. SanDiego> From forth the fatal loins of these two foes SanDiego> A pair of star-cross'd lovers take their life; NoBrainer> REJECT 2 ("This will never, ever sell.") SanDiego> THANKS NoBrainer> DONT_CALL_US_WE'LL_CALL_YOU9. Security Considerations In accordance with the principles of the humane treatment of animals, the design of IMPS specifically prohibits the CRITIC from contacting the SIMIAN directly and hurting its feelings. BARDs and CRITICs are also separated because of fundamental incompatibilities and design flaws. The security considerations for the rest of IMPS are similar to those for the original Internet protocols. Specifically, IMPS refuses to learn from the mistakes of the past and blithely repeats the same errors without batting an eye. Spoofing and denial of service attacks abound if untrusted entities gain access to an IMPS network. Since all transmissions occur in cleartext without encryption, innovative works are subject to theft, which is not a significant problem unless the network contains entities other than CRITICs. The open nature of BARDs with respect to IAMB-PENT messages allows a BARD to borrow heavily from transmitted works, but by design BARDs are incapable of stealing transcripts outright. The ZOO may be left open to exploitation by pseudo-SIMIANs from around the world. A third party could interrupt communications between a ZOO and a SIMIAN by flooding the SIMIAN with packets, incrementing the message ID by 1 for each packet. More heinously, the party could exploit the KEEPER protocol by sending a single STOP request to each SIMIAN, thus causing a massive denial of service throughout the ZOO. The party could also spoof a CHIMPChristey Informational [Page 16] RFC 2795 The Infinite Monkey Protocol Suite (IMPS) 1 April 2000 request or send false information such as a DEAD status, which could cause a ZOO to attempt to replace a monkey that is still functioning properly. In addition, if a ZOO repeatedly rejects a SIMIAN's requests (especially those for FOOD, WATER, and VETERINARIAN), then the ZOO may inadvertently cause its own denial of service with respect to that particular SIMIAN. However, both KEEPER and CHIMP allow the ZOO to detect this condition in a timely fashion via the NORESPONSE or DEAD status codes. All BARDs are inherently insecure because they face insurmountable financial problems and low prioritization, which prevents them from working reliably. In the rare cases when a BARD implementation overcomes these obstacles, it is only successful for 15 minutes, and reverts to being insecure immediately thereafter [14]. Since a CRITIC could significantly reduce the success of a BARD with an appropriate PAN response, this is one more reason why BARDs and CRITICs should always be kept separate from each other. It is expected that very few people will care about most implementations of CRITIC, and CRITICs themselves are inherently insecure. Therefore, security is not a priority for CRITICs. The CRITIC may become the victim of a denial of service attack if too many SIMIANs submit transcripts at the same time. In addition, one SIMIAN may submit a non-innovative work by spoofing another SIMIAN (this is referred to as the Plagiarism Problem). A CRITIC response can also be spoofed, but since the only response supported in PAN version 1 is REJECT, this is of little consequence. Care must be taken in future versions if a GRUDGING_ACCEPTANCE response is allowed. Finally, a transcript may be lost in transmission, and PAN does not provide a mechanism for a ZOO to determine if this has happened. Future versions of IMPS may be better suited to answer this fundamental design problem: if an innovative work is lost in transmission, can a CRITIC still PAN it? Based on the number of packet-level vulnerabilities discovered in recent years, it is a foregone conclusion that some implementations will behave extremely poorly when processing malformed IMPS packets with incorrect padding or reserved bits [15] [16] [17].Christey Informational [Page 17] RFC 2795 The Infinite Monkey Protocol Suite (IMPS) 1 April 2000 Finally, no security considerations are made with respect to the fact that over the course of infinite time, monkeys may evolve and discover how to control their own SIMIAN interfaces and send false requests, or to compose and submit their own transcripts. There are indications that this may already be happening [18].10.
