Identity-based subgroups and information exchange in adversarial policy networks

Information Exchange in Policy Networks

Information exchange in policy networks is usually attributed to preference similarity, influence reputation, social trust and institutional actor roles. We suggest that political opportunity structures and transaction costs play another crucial role and estimate a rich statistical network model on tie formation in the German toxic chemicals policy domain. The results indicate that the effect o...

Coverless Information Hiding Based on Generative adversarial networks

Traditional image steganography modifies the content of the image more or less, it is hard to resist the detection of image steganalysis tools. To address this problem, a novel method named generative coverless information hiding method based on generative adversarial networks is proposed in this paper. The main idea of the method is that the class label of generative adversarial networks is re...

Identity-based Key Exchange Protocols for Ad Hoc Networks

In this work we present a set of authentication and key exchange protocols that use identity-based pre-shared keys from pairings. We show that those protocols are attractive for an implementation in ad hoc networks. We start with introducing a light-weight protocol that uses purely symmetric crypto primitives. We then gradually add more security features. We analyze the security and performance...

Generate Identity-Preserving Faces by Generative Adversarial Networks

Generating identity-preserving faces aims to generate various face images keeping the same identity given a target face image. Although considerable generative models have been developed in recent years, it is still challenging to simultaneously acquire high quality of facial images and preserve the identity. Here we propose a compelling method using generative adversarial networks (GAN). Concr...
