Application Of Key Agreement Protocol

This protocol is subject to a dictionary attack: an earpiece can simply record the first message (gx, h, IDA) and test the candidate tags pwa vs. h. If the opponent receives pwa h-H (pw,gx,IDA,IDB) for a given value, it is very likely that he has found the password. Note that the password never appears directly in the protocol. The key management protocol is designed to address the following features: a key authentication protocol for IMS (IMS) has been proposed by [CHE 08] to determine the above problem. This IMSKAAP offers a secure key exchange and allows servers to support legal interceptions by integrating the benefits of the KTAP and KAAP protocols. A new key exchange protocol has been established, extending the IKE protocol, which uses IPSec to trade AS to protect AH and ESP traffic. The new key exchange protocol is authenticated Internet Protocol (AuthIP). AuthIP is an extension of the current IKE, but offers additional support for the mode of transport in order to make it more efficient. It was designed to simplify the key exchange process by reducing the complexity and number of round trips required. Isolated work use rate: represented by application programs or VMs performed in the isolated environment; Crypto-session (CS) is a one-way or two-way media stream. A CS is protected by a single instance of a data security protocol.

Sharing hardware resources can be another data protection issue. Some research efforts focus on the analysis and restoration of compromised systems. To solve this security problem, there are two solutions for data protection: one is to isolate the data at the application level [JAI 08] and the other is to isolate the data at the hardware level [AZA 11]. Multimedia Internet KEYing (MIKEY) is another key exchange protocol for SRTP, defined in RFC 3830.12. It is mainly designed for peer-to-peer groups, simple 1:n and small groups (interactive). One of the main multimedia scenarios considered in THE design of MIKEY was the multimedia entertainment scenario in which users can interact and communicate in real time. In these scenarios, peers can be expected to set up multimedia sessions with each other in which a multimedia session can consist of one or more secure media streams (for example. B, SRTP feeds).

Below are some typical scenarios for multimedia applications that may occur: the original protocol and still best known for the key agreement was proposed by Diffie and Hellman (see the Diffie-Hellman key agreement) as well as their concept of cryptography with public keys. Basically, Alice and Bob users send key public values through an uncertain channel. Based on the knowledge of the corresponding private keys, they are able to correctly and safely calculate a common key value. An earpiece, however, is not capable of this key with only the knowledge of… Dictionary attacks are specific to PAKE protocols. However, the privacy and security of the well-known session key were first taken into account in the traditional key exchange, and then transposed in the password-based case. It may be tempting to do this with all the security features that can be set for key exchange in general, but this is not always possible. Opposition to important compromise identities, in which an opponent who has compromised a user`s long-term key can then imitate other parts of that user, is not satisfied by a PAKE: the other owner of the password can always be transmitted to the attacked user.

Key exchange algorithm, often called key exchange protocol, is any method in cryptography that allows the exchange of secret cryptographic keys between two parties, usually via a public communication channel.
