Network-Hiding Communication and Applications to Multi-party Protocols [chapter]

Martin Hirt, Ueli Maurer, Daniel Tschudi, Vassilis Zikas
2016 Lecture Notes in Computer Science  
In a multi-party computation (in short, MPC) protocol over an incomplete network, such a challenge is to hide, to the extent possible, the topology of the underlying communication network.  ...  [ITCS 2015] and by Moran et al. [TCC 2015], existing MPC protocols do not hide the topology of the underlying communication network.  ...  At a very high level, [MOR15] uses public-key encryption and (semi-honest) multi-party computation to implement a proof-of-concept network-hiding communication protocol, which emulates a complete network  ...

Prevention of Selective Jamming Attacks by Using Packet Hiding Methods

2013 IOSR Journal of Computer Engineering  
However, intruders with internal knowledge of protocol specifications and network secrets can launch low-effort jamming attacks that are difficult to detect and counter.  ...  We analyze the security of the proposed methods and evaluate their computational and communication overhead.  ...  SS techniques provide bit-level protection by spreading bits according to a secret pseudo-noise (PN) code, known only to the communicating parties.  ...

Topology-Hiding Broadcast Based on NTRUEncrypt

2016 KSII Transactions on Internet and Information Systems  
Secure multi-party computation (MPC) has been a research focus of cryptography in resent studies. However, hiding the topology of the network in secure computation is a rather novel goal.  ...  Inspired by a seminal paper [1], we proposed a topology-hiding broadcast protocol based on NTRUEncrypt and secret sharing. The topology is concealed as long as any part of the network is corrupted.  ...  Albeit secure multi-party computations are usually carried out on computer networks, one important question is always neglected: MPC over an underlying communication network whose structure might be, in  ...
