Coalition Formation in a Legislative Voting Game [PDF]

, 2013
We experimentally investigate the Jackson-Moselle (2002) model where legislators bargain over policy proposals and the allocation of private goods. Key comparative static predictions of the model hold as policy proposals shift in the predicted direction ...

Signature schemes with a fuzzy private key

International Journal of Information Security, 2019
In this paper, we introduce a new concept of digital signature that we call fuzzy signature, which is a signature scheme that uses a noisy string such as biometric data as a private key, but does not require user-specific auxiliary data (which is also ...

A Private Key Management Scheme on Blockchain Against Collusion Attacks [PDF]

Jisuanji gongcheng, 2020
To address the security of the recovery of lost private keys on the blockchain,this paper proposes a distributed management scheme for private keys based on threshold secret sharing.The scheme combines the user’s private key with the secret password as a

Improving the security of LSB image steganography

JOIV: International Journal on Informatics Visualization, 2019
Steganography is the technique of hiding secret data (message) within any media such as digital color image. In this paper we will merge steganography process with cryptography process in order to increase the security of the proposed method.

New, efficient and robust, fiber-based quantum key distribution schemes [PDF]

, 2002
We present a new fiber based quantum key distribution (QKD) scheme which can be regarded as a modification of an idea proposed by Inoue, Waks and Yamamoto (IWY) [1].

A New Secret key Agreement Scheme in a Four-Terminal Network

, 2011
A new scenario for generating a secret key and two private keys among three Terminals in the presence of an external eavesdropper is considered. Terminals 1, 2 and 3 intend to share a common secret key concealed from the external eavesdropper (Terminal 4)
