Technology and Business
Models for the Broadband Wireless Internet
Abstract
We see wireless communications evolving toward an integrated
IP (Internet Protocol) framework for a diversity of access
systems, including cellular mobile, WiFi, WiMax, UWB, Bluetooth,
and Zigbee. Furthermore, many of these diverse access systems
will use similar OFDM (orthogonal frequency division multiplexing)
formats for broadband "wireless Internet" services.
At the same time, inexpensive WiFi technology encourages
a proliferation of small WISPs (wireless Internet Service
Providers) for public access WiFi services, and WiMax and
UWB may similarly stimulate new, competitive providers. This
talk offers my perspective on the trends for both diversity
and integration, and how they might be reconciled in industry
and business models for franchised, third-party-subsidized,
and overlaid services structures. I will also include the
important aspects of network resilience and emergency services
as contributing to the shape of future broadband wireless
networking.

Next Generation Broadband
Wireless Access Networks
Abstract
Broadband wireless access is one of the most challenging
tasks which require multi-facet approach to provide seamless
connectivity to a large number of users. Current generation
low capacity 2G and 2.5G networks are already offering services
to more customers (world wide) than by their counterpart
fixed networks. However, current generation wireless access
networks support limited type and/or number of services.
Next generation broadband wireless access networks need to
be developed to support all services supported by current
generation fixed networks. Current generation 2/2.5G and
recently arrived 3G technologies will only be able to support
partial needs of diverse range of users. We need to develop
smarter access network technologies to fulfill the needs
of future customers. Next generation networks not only requires
advanced high capacity physical layer but also requires intelligent
integration of higher layers. In this presentation I shall
review various emerging wireless access network standards,
such as WCDMA air interface, WiFi based IEEE802.11WLANs,
HIPERLAN standard, IEEE802.16 based WiMax and IEEE802.20
based MBWA (Mobile Broadband Wireless Access) standard. In
addition to those standards I shall also examine the Vertical
handover technique. A vertical handover technique will allow
mobiles to connect to suitable access networks depending
on its current demand and available network resources. Wireless
access network scenario is different from a fixed network
scenario. In case of a wireless access network some of the
terminals will be mobile; hence, those mobiles will be able
to select an access network using vertical handover architecture
to remain in always best connected mode.

Security for E-Government Applications in a Ubiquitous Society
Abstract
Security plays a vital role in developing e-government applications in an increasingly interconnected ubiquitous society, where the continuous, seamless use of wireless networking and broadband technologies can ensure secure communications with anyone, any organisations, anytime, anywhere, any networks and any devices.
We will address how to improve and modernise the secure e-government applications and services as well as developing an IT security strategy for e-government. Recently, Internet and wireless communications becomes our channels for interacting with government websites. We envisage that the citizens will interact electronically with the central government, local government and business, financial, commercial, educational and healthcare sectors via personal computers, public telephones, mobile phones, interactive Digital TV, WiFi, WiMAX and kiosks.
In order to establish confidence and trust for e-government applications such as secure e-mails, e-commerce, e-healthcare, e-education, e-visa and e-passport, the citizens will need to be confident that applications are secure and their privacy must be maintained. E-government must provide appropriate common security services such as mutual authentication, confidentiality, integrity, availability, accountability, anonymity and non-repudiation.
However, there exist a number of security threats for e-government services such as impersonation, data modification, denial of service, repudiation, replay attacks and brute force attacks. One of the most dangerous security threats is the impersonation, in which somebody claims to be somebody else.
The security services that encounter this threat are identification and mutual authentication. Identification is the service where an identity is assigned to a specific individual, and authentication the service designed to verify a user's identity. The verifier can be identified and authenticated by what he knows (e.g. password), by what he owns (e.g. smart card) or by his human characteristics (biometrics including fingerprints, face and voice recognition and retina scan).
The mutual authentication service will enable secure electronic interactions between Government-to-Citizens (G2C), Government-to-Business (G2B) and Government-to-Government (G2G). This service could be employed by introducing national identity cards or e-passports schemes with embedded smart card technologies that consist of personal, biometric and private information could be stored in secure tamper resistance hardware modules.
In our novel e-government applications, secure digital signatures based on robust cryptosystem such as elliptic curve cryptosystem will be used due to computationally more efficient than the conventional public key cryptosystems such as RSA and DSS.
In addition, one property of authentication that was traditionally not considered to be important, but is becoming increasingly relevant, is the issue of deniability. An example of a potential use of a deniable authentication service would be in including electronic voting systems. For example in government elections, a voter will want to securely place their vote. However, it is extremely important that the content of their vote cannot be traced back to them. Hence, any protocol exchange between a voter and an electronic system should be deniable.
Adapting above mentioned our novel techniques, we can build the secure e-government, e-education, e-healthcare services by the appropriately deploying the public key infrastructure system with vigorous legislative framework in places that will help to create a truly global ubiquitous society for the future.
