Title: Privacy-preserving in
Location-Based Services
¡¡ |
Abstract:
In this talk we first
systematically present the current research status of the
privacy-preserving in Location-Based Services (LBS), including
the location privacy definition, the attacks and adversaries,
the location privacy preserving mechanisms, the location privacy
metrics, and the current status of location based applications.
Then we will discuss three application cases. The first
application case is to enhance privacy of LBS in wireless
vehicular networks, where we develop an LBS privacy-enhancing
scheme that is dedicated to the vehicular environment by
exploring the unique features of queries from in-vehicle users.
In the second application case we present a private Blockchain
based method for task payment that effectively preserves
individual privacy in the entire crowdsensing system. And in the
third applicaiton case we deal with the trajectory privacy
preserving in mobile crowdsensing, where we develop a location
privacy preserving framework based on economic models for mobile
crowdsensing applications. |

angles and reflects on the urgently needed collective efforts
from various research communities to collaborate on those. Our
approach fundamentally challenges the current thinking and
understanding of scientific, technological, and political
paradigms in tackling the engineering of IoT systems. We discuss
technical paradigms and research challenges in the domains of
Cloud and Edge Computing as well as the requirements of people
in such systems. We will explore how these novel approaches

Title: Training Acceleration
for Distributed Machine-Learning Systems at Scale: A
Network-Centric Approach |
Abstract:
Distributed machine-learning (ML) systems,
in response to big data and big models, play an important role
in fueling the emerging artificial intelligence revolution. In
this context, the parameter server (PS) framework has been
widely used to train models at scale in modern ML systems, such
as Petuum, MxNet, TensorFlow and Factorbird. It tackles the
big-data problem by having worker nodes perform data-parallel
computation, and server nodes maintain globally shared
parameters. However, when training models of large size, worker
nodes frequently pull parameters from server nodes and push
updates to server nodes, often resulting in high communication
overhead. Our investigations show that modern distributed ML
applications could consume up to 5 times more time on
communication than computation. To address this problem, we
propose an optimized communication layer for the PS framework,
called as Parameter Flow (PF). The PF employs a Swiss-army-knife
approach by staking three complementary techniques in the system
level. First, we introduce an update-centric communication (UCC)
model to exchange data between worker/server nodes via two
operations: broadcast and push. Second, we develop a dynamic
value-bounded filter (DVF) to reduce network traffic by
selectively dropping updates before transmission. Third, we
design a tree-based streaming broadcasting (TSB) system to
efficiently broadcast aggregated updates among worker nodes. Our
proposed PF can significantly reduce network traffic and
communication time. Extensive performance evaluations have
showed that PF can speed up popular distributed ML applications
by a factor of up to 4.3 in a dedicated cluster, and up to 8.2
in a shared cluster, compared to a generic PS system without PF.
The PF framework has been used by a few industry partners. |

Title:
Security Proof of Digital Signatures |
Abstract:
Digital signatures are the foundation of modern cryptography. We
prove the security of a signature scheme by reducing an attack
to solving an underlying hard problem. An ideal security
reduction should be a tight reduction under a standard
assumption in the standard security model without random
oracles. Unfortunately, it is hard to program a security
reduction capturing the above four features. In this talk, I
will focus on tight reduction for digital signatures and
introduce two different methods towards tight reduction. |

Title: Blockchain-based online
voting |
Abstract:
A blockchain is a public, append-only, immutable ledger
maintained by a decentralised peer-to-peer network. Whilst first
designed for digital currencies without trusted third parties,
blockchain technology has now moved into many fields beyond
finance. In this talk, we focus on blockchain-based online
voting. There are a number of existing proposals for such a
system, using the blockchain as a public bulletin board to store
the voting data, such as FollowMyVote and TIVI. These proposals
achieve voter privacy by involving trusted authorities that
obfuscate the relation between real-world identities and keys,
or by shuffling encrypted votes before decrypting. We propose a
self-tallying online voting system using a smart contract
deployed on Ethereum. The system reduces the responsibilities of
election authorities to a minimum and allows candidate ranking,
instead of just voting for one candidate. The voting mechanism
is inspired by score voting, which enables voters to assign
points to different candidates directly without any restrictions
apart from the total number of available points specified. |

Title:
Resource Provisioning for the Internet of
Things: Open Issues and Challenges |
Abstract:
Recent technological trends such as
Industry 4.0 introduced new challenges that push the limit of
current computer and networking architectures. It demands the
connection of thousands, if not millions, of sensors and mobile
devices coupled with optimized operations to automate various
operations inside factories. This led to the new era of Internet
of Things (IoTs) where lightweight (possibly mobile) devices are
envisaged to send vital information to cloud data centres
(mobile and fixed infrastructure) for further processing and
decision making.
Current cloud computing systems, however, are not able to
efficiently digest and process collected information from IoT
devices with strict response requests for two main reasons: (1)
the round trip delay between IoT devices to the processing
engines of cloud could exceed an application¡¯s threshold, and
(2) network links to cloud resources could be clogged when IoT
devices flush data in an uncoordinated fashion. Fog and Edge
Computing are two solutions to address both of the previous
problems. Though designed to alleviate the same problem, they
have fundamental differences that make adopting one more
applicable than the other.
This talk will overview the practical concerns of today¡¯s IoT
implementations through tackling the most important obstacles
that hinder their adoption. First, production of applicable
network (fixed and mobile) latency models to capture all
elements of IoT platforms. Second, building a holistic platform
to orchestrate various inter-related layers of IoT platforms,
including connectivity, big-data analytics, and workload
optimization. Third, proposing viable solutions that can be
actually implemented in IoT-based applications. More details
will be provided about the above issues during the talk.
