Impersonation Attack Sample Clauses
The Impersonation Attack clause defines the responsibilities and protections related to situations where one party fraudulently assumes the identity of another to gain unauthorized access or benefits. In practice, this clause typically outlines the steps parties must take to verify identities, the procedures for reporting suspected impersonation, and the allocation of liability if such an attack occurs. Its core function is to mitigate the risks associated with identity fraud, ensuring that both parties are aware of their obligations and the consequences of failing to prevent or respond to impersonation attempts.
Impersonation Attack. In this attack, assume that Xxx tries to impersonate as a legal meter to the NAN gateway. To do that, Xxx randomly picks uSMeve and computes ASMeve using uSMeve P and fabricates a false BSMeve . Eve then computes own messages, i.e., L1eve = H(SMIDeve NID ASMeve BSMeve T 1eve) and Y 1eve = MACL1eve [SMIDeve , T 1eve, ASMeve ] and sends αeve, Q1, ASMeve , Y 1eve, φeve, T 1eve to the NAN gate- way. However, the NAN gateway cannot obtained the real identity of the meter since it is encrypted in Q1 = ESTj [SMIDj , NID, T 1] therefore Xxx’s fake identity can- forward secrecy(MFS). Here, PFS defines that if a compromise of long-term private key of either the legitimate parties (e.g., a SM or NAN gateway) should not be compromising secrecy of the previously established sessions. Whereas, MFS satisfies – whenever the master key of a legitimate entity is being compromised then the protocol should hold the security of session key. The proposed LAKA therefore holds both PFS and MFS properties. For instance, assume that if the long- term secret keys (e.g., (STj, SMprj, Mk) of meter and NAN are exposed to Eve. However Xxx still cannot determine the previous session keys because each previous session between the meter and XXX is computed independently and fresh i.e., (SK = H(SMIDj NID ASMj CN WSMj ))) that includes ASMj (= uSMj P ), CN (=vN P ) and WSMj (=uSMj CN ). Here uSMj and vN are random numbers of the meter and NAN, respectively. In addition, with the fact of the ECDLP hardness, Xxx cannot determine the real value of uSM and vN , which are random numbers. Therefore, the proposed scheme holds FS.
Impersonation Attack. Impersonation attack means that illegal users impersonate legal ones and pass the authentication process with the stolen authenticated message to enter the system. In the proposed group authenticated key agreement mechanism, the attacker can not obtain the authenticated message of KGSi because KGSi is encrypted. Without KGSi , the attacker can not impersonate Ui or GWN. Therefore, PL-GAKA can defend impersonation attacks.
Impersonation Attack. Motivation of impersonation attacks is to take place any of B-GKAP entity during the protocol execution. To do that, an attacker needs to be able to generate the signature of an entity. Since our models are based on [11], we also utilize Xxxxxxx signature scheme [54] for outputs of B-GKAP functions. As stated in [55] and [56], Xxxxxxx is secure against impersonation and related key attacks, respectively.
Impersonation Attack. To successfully perform this attack and forge IoT devices, the adversary needs to duplicate messages = ℎ( ∥ ∥ ∥ 1) and = ℎ( ∥ ∥ 2) to be certified by the shared protocol. An adversary can never generate a valid message to forge an authorized device in the network because it does not have access to private key and original . Our proposed protocol is able to withstand impersonation attack.
Impersonation Attack. If an attacker intends to impersonate a legitimate entity (e.g., SD), it must break the mutual authentication security, which is proven in Sections VI-A and VI-B. Therefore, the proposed scheme is secure against the imperson- ation attack.
Impersonation Attack. In ZSM-2 protocol, they did not consider about the existence of malicious participants. Also, their batch verification only executes if the message is correctly generated with secret value r, not if the message is sent by correct user. Therefore, the malicious insider who knows the secret value r can impersonate the other users, that is, impersonation attack by the insider will happen. The following is an attack on the protocol that the legitimated user Uk impersonates the user Xx. = < H2(r||L)xxX, kiPpub + H2(r||L)Si >
Impersonation Attack. By impersonating a legiti- mate entity (i.e., SD), an attacker can interact with the server and successfully pass the authentication process. Similarly, in cross-domain environments, an attacker might impersonate ESs across multiple domains, interacting with devices to pass the authentication and obtain relevant information about tasks.
Impersonation Attack. In this type of attack, the attacker impersonates as a legitimate client and forges the authentication messages using the information obtained from the authentication protocol. The attacker can attempt to modify a login request message (IDi*, C2, T) into (IDi*, C2*, T*) so as to succeed in the authentication phase, where T* is the attacker’s current date and time. However, such a modification will fail in Step 1 of the authentication phase because the attacker has no way of obtaining the value of C1 = H (IDi* | TTSA | x) to compute the valid parameter C2*. Moreover, the attacker can not compute the agreed session key SK = H (C1 | H (TTSA) | T) between the user Ui and the server S. Therefore, the proposed protocol is secure against impersonation attack.
Impersonation Attack. The adversary can simulate a set of C(Ui) and yri through a valid login request, that is, impersonate a user in the group. However, the verification involves the user’s private key and the encrypted transmission of data in communica- tion, thus the proposed scheme can resist imperson- ation attack.
Impersonation Attack. According to the analysis of Subsection V-A2, A is unable to produce a legitimate AKA request message, M1 =< X2, CT1, MAC1, T1 >, on behalf of EUi, without being 21 i i aware of the secrete parameters PID , PID 22 EUi requires to recall its old identity IDi, and S performs and i S i Dj 23 the following steps to issue a new mobile terminal to EUi. 24 Step RVP-1 : EUi selects its old identity IDi and forwards 26 ⊕ 25 it to S. S calculates EUi’s pseudo-identity PIDi as Zi =
