An Active Attack on a Multiparty Key Exchange Protocol
نویسندگان
چکیده
The multiparty key exchange introduced in Steiner et al. and presented in more general form by the authors is known to be secure against passive attacks. In this paper, an active attack is presented assuming malicious control of the communications of the last two users for the duration of only the key exchange.

In secure multiparty computation (SMC), a group of users jointly and securely computes a mathematical function on their private inputs, such that the privacy of their private inputs will be preserved. One of the widely used applications of SMC is the secure multiparty summation which securely computes the summation value of the users’ private inputs. In this paper, we consider a secure multipar...

In this paper we have proposed an efficient password security of ThreeParty and Multiparty Key Exchange Protocol based on Elliptic Curve Discrete Logarithm Problem. In three party Key exchange protocols allow two clients with a trusted Server where they registered their password and communicate over a public network to establish a common secret key called session key. Similary multiparty key ex...

In this work, we introduce an active attack on a Group Key Exchange protocol by Burmester and Desmedt. The attacker obtains a copy of the shared key, which is created in a collaborative manner with the legal users in a communication group.

Two conditions must be satisfied in a secure quantum key agreement (QKA) protocol: 1) Outside eavesdroppers cannot gain the generated key without introducing any error; 2) The generated key cannot be determined by any non-trivial subset of the participants.That is, a secure QKA protocol can not only prevent the outside attackers from stealing the key, but also resist the attack from inside part...
متن کاملAn Efficient Password Security of Multi-Party Key Exchange Protocol based on ECDLP
In this paper we have proposed an efficient password security of multiparty Key Exchange Protocol based on Elliptic Curve Discrete Logarithm Problem. Key exchange protocols allow a group of parties communicating over a public network to establish a common secret key called session key. Due to their significance by in building a secure communication channel, a number of key exchange protocols ha...
