-/*
-  This identity hiding process tests whether the rosenpass protocol is able to protect the identity of an initiator or responder.
-  The participants in the test are trusted initiators, trusted responders and compromised initiators and responders.
-  The test consists of two phases. In the first phase all of the participants can communicate with each other using the rosenpass protocol.
-  An attacker observes the first phase and is able to intercept and modify messages and choose participants to communicate with each other
-
-  In the second phase if the anonymity of an initiator is being tested then one of two trusted initiators is chosen.
-  The chosen initiator communicates directly with a trusted responder.
-  If an attacker can determine which initiator was chosen then the anonymity of the initiator has been compromised.
-  Otherwise the protocol has successfully protected the initiators’ identity.
-
-  If the anonymity of a responder is being tested then one of two trusted responders is chosen instead.
-  Then an initiator communicates directly with the chosen responder.
-  If an attacker can determine which responder was chosen then the anonymity of the responder is compromised.
-  Otherwise the protocol successfully protects the identity of a responder.
-
-  The Proverif code treats the public key as synonymous with identity.
-  In the above test when a responder or initiator is chosen what is actually chosen is the public/private key pair to use for communication.
-  Traditionally when a responder or initiator is chosen they would be chosen randomly.
-  The way Proverif makes a "choice" is by simulating multiple processes, one process per choice
-  Then the processes are compared and if an association between a public key and a process can be made the test fails.
-  As the choice is at least as bad as choosing the worst possible option the credibility of the test is maintained.
-  The drawback is that Proverif is only able to tell if the identity can be brute forced but misses any probabilistic associations.
-  As usual Proverif also assumes perfect encryption and in particular assumes encryption cannot be linked to identity.
-
-  One of the tradeoffs made here is that the choice function in Proverif is slow but this is in favour of being able to write more precise tests.
-  Another issue is the choice function does not work with queries so a test needs to be run for each set of assumptions.
-  In this case the test uses secure rng and a fresh secure biscuit key.

-# Additional files
-
-This folder contains additional files that are used in the project.
-
-## `generate_configs.py`
-
-The script is used to generate configuration files for a benchmark setup
-consisting of a device under testing (DUT) and automatic test equipment (ATE),
-basically a strong machine capable of running multiple Rosenpass instances at
-once.
-
-At the top of the script multiple variables can be set to configure the DUT IP
-address and more. Once configured you may run `python3 generate_configs.py` to
-create the configuration files.
-
-A new folder called `output/` is created containing the subfolder `dut/` and
-`ate/`. The former has to be copied on the DUT, ideally reproducible hardware
-like a Raspberry Pi, while the latter is copied to the ATE, i.e. a laptop.
-
-### Running a benchmark
-
-On the ATE a run script is required since multiple instances of `rosenpass` are
-started with different configurations in parallel. The scripts are named after
-the number of instances they start, e.g. `run-50.sh` starts 50 instances.
-
-```shell
-# on the ATE aka laptop
-cd output/ate
-./run-10.sh
-```
-
-On the DUT you start a single Rosenpass instance with the configuration matching
-the ATE number of peers.
-
-```shell
-# on the DUT aka Raspberry Pi
-rosenpass exchange-config configs/dut-10.toml
-```
-
-Use whatever measurement tool you like to monitor the DUT and ATE.

       Rosenpass is used to create post-quantum-secure VPNs. Rosenpass computes a shared key, WireGuard (WG) [@wg] uses the shared key to establish a secure connection. Rosenpass can also be used without WireGuard, deriving post-quantum-secure symmetric keys for another application. The Rosenpass protocol builds on “Post-quantum WireGuard” (PQWG) [@pqwg] and improves it by using a cookie mechanism to provide security against state disruption attacks.

 ICR5 and ICR6 perform biscuit replay protection using the biscuit number. This is not handled in `load_biscuit()` itself because there is the case that `biscuit_no = biscuit_used` which needs to be dealt with for retransmission handling.

-### Denial of Service Mitigation and Cookies
-
-Rosenpass derives its cookie-based DoS mitigation technique for a responder when receiving InitHello messages from Wireguard [@wg]. 
-
-When the responder is under load, it may choose to not process further InitHello handshake messages, but instead to respond with a cookie reply message (see Figure \ref{img:MessageTypes}).
-
-The sender of the exchange then uses this cookie in order to resend the message and have it accepted the following time by the reciever. 
-
-For an initiator, Rosenpass ignores all messages when under load.
-
-#### Cookie Reply Message
-
-The cookie reply message is sent by the responder on receiving an InitHello message when under load. It consists of the `sidi` of the initiator, a random 24-byte bitstring `nonce` and encrypting `cookie_value` into a `cookie_encrypted` reply field which consists of the following:
-
-```pseudorust
-cookie_value = lhash("cookie-value", cookie_secret, initiator_host_info)[0..16]
-cookie_encrypted = XAEAD(lhash("cookie-key", spkm), nonce, cookie_value, mac_peer)
-```
-
-where `cookie_secret` is a secret variable that changes every two minutes to a random value. `initiator_host_info` is used to identify the initiator host, and is implementation-specific for the client. This paramaters used to identify the host must be carefully chosen to ensure there is a unique mapping, especially when using IPv4 and IPv6 addresses to identify the host (such as taking care of IPv6 link-local addresses). `cookie_value` is a truncated 16 byte value from the above hash operation. `mac_peer` is the `mac` field of the peer's handshake message to which message is the reply.  
-
-#### Envelope `mac` Field
-
-Similar to `mac.1` in Wireguard handshake messages, the `mac` field of a Rosenpass envelope from a handshake packet sender's point of view consists of the following:
-
-```pseudorust
-mac = lhash("mac", spkt, MAC_WIRE_DATA)[0..16]
-```
-
-where `MAC_WIRE_DATA` represents all bytes of msg prior to `mac` field in the envelope.
-
-If a client receives an invalid `mac` value for any message, it will discard the message.
-
-#### Envelope cookie field
-
-The initiator, on receiving a CookieReply message, decrypts `cookie_encrypted` and stores the `cookie_value` for the session into `peer[sid].cookie_value` for a limited time (120 seconds). This value is then used to set `cookie` field set for subsequent messages and retransmissions to the responder as follows:
-
-```pseudorust
-if (peer.cookie_value.is_none()  ||  seconds_since_update(peer[sid].cookie_value) >= 120) {
-    cookie.zeroize(); //zeroed out 16 bytes bitstring
-}
-else {
-    cookie = lhash("cookie",peer.cookie_value.unwrap(),COOKIE_WIRE_DATA)
-}
-```
-
-Here, `seconds_since_update(peer.cookie_value)` is the amount of time in seconds ellapsed since last cookie was received, and `COOKIE_WIRE_DATA` are the message contents of all bytes of the retransmitted message prior to the `cookie` field.
-
-The inititator can use an invalid value for the `cookie` value, when the responder is not under load, and the responder must ignore this value.
-However, when the responder is under load, it may reject InitHello messages with the invalid `cookie` value, and issue a cookie reply message. 
-
-### Conditions to trigger DoS Mechanism
-
-This whitepaper does not mandate any specific mechanism to detect responder contention (also mentioned as the under load condition) that would trigger use of the cookie mechanism.
-
-For the reference implemenation, Rosenpass has derived inspiration from the linux implementation of Wireguard.  This implementation suggests that the reciever keep track of the number of messages it is processing at a given time. 
-
-On receiving an incoming message, if the length of the message queue to be processed exceeds a threshold `MAX_QUEUED_INCOMING_HANDSHAKES_THRESHOLD`, the client is considered under load and its state is stored as under load. In addition, the timestamp of this instant when the client was last under load is stored. When recieving subsequent messages, if the client is still in an under load state, the client will check if the time ellpased since the client was last under load has exceeded `LAST_UNDER_LOAD_WINDOW` seconds. If this is the case, the client will update its state to normal operation, and process the message in a normal fashion.
-
-Currently, the following constants are derived from the Linux kernel implementation of Wireguard:
-
-```pseudorust
-MAX_QUEUED_INCOMING_HANDSHAKES_THRESHOLD = 4096
-LAST_UNDER_LOAD_WINDOW = 1 //seconds
-```
-
 ## Dealing with Packet Loss

 The initiator deals with packet loss by storing the messages it sends to the responder and retransmitting them in randomized, exponentially increasing intervals until they get a response. Receiving RespHello terminates retransmission of InitHello. A Data or EmptyData message serves as acknowledgement of receiving InitConf and terminates its retransmission.

 The responder does not need to do anything special to handle RespHello retransmission – if the RespHello package is lost, the initiator retransmits InitHello and the responder can generate another RespHello package from that. InitConf retransmission needs to be handled specifically in the responder code because accepting an InitConf retransmission would reset the live session including the nonce counter, which would cause nonce reuse. Implementations must detect the case that `biscuit_no = biscuit_used` in ICR5, skip execution of ICR6 and ICR7, and just transmit another EmptyData package to confirm that the initiator can stop transmitting InitConf.

-### Interaction with cookie reply system
-
-The cookie reply system does not interfere with the retransmission logic discussed above. 
-
-When the initator is under load, it will ignore processing any incoming messages.
-
-When a responder is under load and it receives an InitHello handshake message, the InitHello message will be discarded and a cookie reply message is sent. The initiator, then on the reciept of the cookie reply message, will store a decrypted `cookie_value` to set the `cookie` field to subsequently sent messages. As per the retransmission mechanism above, the initiator will send a retransmitted InitHello message with a valid `cookie` value appended. On receiving the retransmitted handshake message, the responder will validate the `cookie` value and resume with the handshake process. 
-
-When the responder is under load and it recieves an InitConf message, the message will be directly processed without checking the validity of the cookie field.

Since it supplies WireGuard with key through the PSK feature using Rosenpass+WireGuard is cryptographically no less secure than using WireGuard on its own ("hybrid security"). Rosenpass refreshes the symmetric key every two minutes.

 As with any application a small risk of critical security issues (such as buffer overflows, remote code execution) exists; the Rosenpass application is written in the Rust programming language which is much less prone to such issues. Rosenpass can also write keys to files instead of supplying them to WireGuard With a bit of scripting the stand alone mode of the implementation can be used to run the application in a Container, VM or on another host. This mode can also be used to integrate tools other than WireGuard with Rosenpass.

 `rp` is easy to get started with but has a few drawbacks; it runs as root, demanding access to both WireGuard
 and Rosenpass private keys, takes control of the interface and works with exactly one interface. If you do not feel confident about running Rosenpass as root, you should use the stand-alone mode to create a more secure setup using containers, jails, or virtual machines.
