SmokeGrenade: A Key Generation Protocol with Artificial Interference in Wireless Networks

2013 IEEE 10th International Conference on Mobile Ad-Hoc and Sensor Systems, 2013
Leveraging a wireless multi-path channel as a source of common randomness, a number of key generation methods have been proposed according to information-theory security. However, by taking the advantages of node's mobility, existing schemes usually have low generation rate or low entropy.

Improving the Generalized Password-Based Authenticated Key Agreement Protocol

2008 The 3rd International Conference on Grid and Pervasive Computing - Workshops, 2008
Recently, Yeh et al. pointed out that the enhanced version of the generalized password-based authenticated key agreement protocol proposed by Kwon and Song is insecure against the off-line password guessing attacks. But, Yeh et al. did not propose an improved version of Kwon and Song's protocol. Therefore, this paper proposes an improvement of Kwon and

A privacy problem on Hu–Huang's proxy key generation protocol

Computer Standards & Interfaces, 2009
A proxy signature scheme enables an original signer to delegate his signing capability to a proxy signer and then the proxy signer can sign a message on behalf of the original signer. Recently, several ID-based proxy signature schemes have been proposed. ID-based Cryptosystems (ID-Cs) are advantageous than the traditional Public Key Cryptosystems (PKCs)

Security analysis of the generalized key agreement and password authentication protocol

IEEE Communications Letters, 2001
We show that the enhanced version of the generalized key agreement and password authentication protocol, proposed by Kwon and Song (see IEICE Trans. Commun., vol.E83-B, no.9, p.2044-50, Sept. 2000), is insecure against off-line password guessing attacks.

Symmetric-Key Generation Protocol (SGenP) for Body Sensor Network

2018 IEEE International Conference on Communications Workshops (ICC Workshops), 2018
Sensors of a Body Sensor Network (BSN) transmit messages over a non-secure wireless channel. Messages are encrypted using a secret key to attain privacy. In this paper, we propose Secret- key Generation Protocol (SGenP), assuming that all sensors are capable of capturing physiological signals.

Attribute-Based Authenticated Key Exchange Protocol with General Relations

2011 Seventh International Conference on Computational Intelligence and Security, 2011
In this paper, we present a two-party attribute-based authenticated key exchange scheme for a wide class of relations, which are specified by non-monotone access structures combined with inner-produce relations. We prove the security of our scheme under the decisional linear (DLIN) assumption, without random oracle, in our ABCK model, which is a ...

Generic Algorithms and Key Agreement Protocols Based on Group Actions

2001
We propose a Diffie-Hellman-like key agreement protocol based on the computational intractability of reversing group action. The concept of a group action generalizes exponentiation and provides an algorithmic problem harder than the discrete logarithm problem.

Gait-Key

ACM Transactions on Sensor Networks, 2017
Recent years have witnessed a remarkable growth in the number of smart wearable devices. For many of these devices, an important security issue is to establish an authenticated communication channel between legitimate devices to protect the subsequent communications.

Security Analysis of a Server-Aided RSA Key Generation Protocol

2006
Modadugu, Boneh and Kim proposed two RSA key generation protocols (MBK Protocols) to generate the RSA keys efficiently on a low-power handheld device with the help of the untrusted servers, and the servers do not get any useful information about the keys they helped generation.

Code generator for key management protocols

2003
Key management has a fundamental role in secure communications. Designing and testing of key management protocols is tricky. These protocols must work flawlessly despite of any abuse. The main objective of this work was to design and implement a tool that helps to specify the protocol and makes it possible to test the protocol while it is still under ...
