What Is Authenticated Key Agreement Protocol
In summary, the performance of our protocol is better than that of the other two protocols. In addition, our protocol is superior to the Dang protocol for resisting attacks. Therefore, our protocol has a better performance in the vanETs environment compared to previous 2PAKA protocols based on ID. Definition 3 (ID-eCK security). For Opponent C, it designates the event that Opponent C can know the correct value of b in the way a query is sent to new instances. Therefore, the advantage of opponent C . If a 2PAKA protocol can meet the following requirements, this protocol is considered an ID-eCK security. (1) For each TPP opponent, the probability of success of knowing the correct b is negligible. This means that this is a negligible value.
(2) After concluding a meeting, two honest parties can obtain the same meeting key. (ii) Requests. As before, S contains four empty tables, and to deal with the corresponding queries. S responds to these C queries as follows. (1) Challenger S has a blank list in the form of . i) If the list already has matching input, S returns to C. (ii) Otherwise S checks the entire table. If the item is found, S will enter the new entry into the list. If this is not the case, it is randomly selected by S and the corresponding data are written in. (2) StaticKeyReveal ().
is revealed by S an C.(3)MasterPrivateKeyReveal. Challenger S responds to this request with . (4) EphemeralKeyReveal (). If so, stop. Otherwise, S returns the volatile key of C. (5) Send (, M). S manages a blank list in the form of . i) If , S X returns to C. (ii) Si , S Y returns to C. Then looks for the corresponding entry in .
When the item is obtained by S, the challenger sits down and the board is added with this new entry. Conversely, the selection is taken at random from S and the corresponding item is inserted into the table. iii) Under other conditions, S responds to C in accordance with protocol specifications. The following difficult mathematical problems are some basic tools that are used to analyze the security of the AKA protocol. Key mous that is verified by the password requires the separate implementation of a password (which may be smaller than a key) in a way that is both private and integrity. These are designed to withstand man-in-the-middle and other active attacks on the password and established keys. For example, DH-EKE, SPEKE and SRP are Diffie-Hellman password authentication variants. In VANETs, communication channels between vehicles and nearby road infrastructure are generally implemented through special DSRC protocols . Using these channels, a vehicle can send messages, such as information or traffic conditions, to nearby vehicles and road infrastructure for a uniform period. This information can be used by drivers to plan, revise and optimize their routes. Depending on the level of connectivity of a city, the traffic management centre (a trusted authority) can redirect traffic, make certain adjustments to improve traffic flow and thus reduce traffic structure. In this module, the performance of our protocol is analyzed according to calculation costs and deadlines.
We also show that our protocol will be compared to other related protocols in terms of effectiveness [13, 14]. To avoid the use of additional off-band authentication factors, Davies and Price proposed the use of Ron Rivest and Adi Shamir`s Interlock protocol, which has come under subsequent attack and refinement. (ii) Requests. To deal with, and sessionKeyReveal C queries, the challenger first manages the corresponding empty lists, and . Then the challenger responds S to all C queries as below: (1). In the set-up phase, where the long-term secret key of each party is set, S inserts the entry in.
