The password-authenticated key agreement typically includes methods such as: MIKEY can work in three different modes: pre-shared key with key transport, public key with key transport, and public key with authenticated DH key exchange. A subsequent extension provides for a DH exchange in pre-shared key mode. The data security protocol is the security protocol, such as SRTP, that is used to protect the media session. Be G a large cyclic multiplicative group with generator for a fixed cyclic group. This method creates a DH key that is used as a TGK. This method is used only to create individual peer-to-peer keys, not a group key. The initiator sends a message to the responder that provides a secure way to assign the initiator`s DH value to the responder. The DH value must be random/pseudo-random and selected secretly based on the security protocol settings. The signature covers the initiator`s MIKEY message with the initiator`s signing key. The responder then securely returns a message to pass the dh value of the responder to the initiator. The DH value must also be random/pseudo-random and must be selected secretly.
A timestamp contained in the original initiator message is the same as the timestamp in the answering machine message. The answering machine signature covers the answering machine`s MIKEY message with the answering machine`s signature key. Online dictionary attacks are active attacks in which the opponent tries to guess the password through successive login attempts: the opponent continues to manage the protocol, trying different passwords, and when the opposing party stops canceling, the opponent knows that he has guessed the right password. It is clear that the design of the protocol cannot prevent this attack. However, a well-built PAKE should only allow you to test one password per login attempt. From that point on, it is up to the application that supports the protocol to specify how many unsuccessful attempts can be tolerated before, for example, the target account is locked.

Dummy password authentication protocol. Therefore, since a large number of IoT devices are likely to be mobile devices, a mobility management protocol is required to maintain IP connectivity, for example via the 6LoWPAN standard, as proposed in [126]. Other work, such as [127], deals with efficient video distribution in mobile multimedia IoT applications, while [128] investigates the interaction of smart objects with traditional web technologies using a mobile Bluetooth platform. Social relationships in mobile nodes in IoT using a cognitive model are studied in [129], while the use of NFC for payments with mobile devices in the so-called Web of Things (WoT) is studied in [130], which proposes a lightweight architecture based on RESTful approaches. Abdalla and Pointcheval (2005) also proposed a new password-based tripartite authentication protocol, providing proof of security in the Random-Or-Real (or AFP) model. The opponent`s initial assumptions, including the state of each protocol participant, are provided with a formal definition of the opponent`s advantage (i.e. the opponent`s target). This enemy model has only a subset of all the capabilities of Bellare Rogaway`s original model (Bellare and Rogaway, 1993; 1995; Bellare et al., 2000), which considerably weakens the adversary. Farash and Attari (2014) then used an adversary with full control over the communication network in proof of security of their password-authenticated key exchange protocol with three parties, the adversary model being built from the enemy model used by Abdalla and Pointcheval (2005). This protocol is vulnerable to a dictionary attack: a spy can simply record the first message (gx, h, IDA) and test the pw′ candidate passwords against h. If the opponent receives pw′ h=H(pw′,gx,IDA,IDB) for a value, it is very likely that he has found the password. Note that the password is never displayed directly in the log.
The key management protocol is designed to have the following characteristics: SIP proxy servers: These are involved in the key exchange process to derive session key K, which ensures that SIP proxy servers support legitimate interception. Zhang et al. also focus on the 5G EAP-TLS protocol in [97]. There, the authors expanded their previous work in [96] and used the ProVerif tool. This allows them to model the behavior of the protocol more accurately. For formal verification, the authors consider two authentication agreements and three non-disclosure agreements. Authentication instructions, namely that the home network and the subscriber must agree on the identity of the other after a successful termination of the protocol and that both parties agree on the pre-master key, are falsified. Non-disclosure agreements can be verified, which means that the attacker cannot obtain the persistent identifier, pre-master key, or session key of the subscription from an honest subscriber. Additionally, the authors suggest a fix and prove that the patch meets the specified security properties.
The first password-authenticated key recovery methods were described by Ford and Kaliski in 2000. Key recovery with password authentication is a process in which a client receives a static key in a password-based negotiation with a server that knows the data associated with the password. B, such as the Ford and Kaliski methods….
