Tutorial 3: MORNING
Title: Digital Signatures - Whom do you trust? The technology
and the standard
Instructor:
Hoyt Kesterson is a Fellow at Bull Worldwide Information Systems in Phoenix,
Arizona
Hoyt.Kesterson@bull.com
ABSTRACT
The use of public key encryption for digital signature provides a high
level of confidence that when a digitally signed document is verified with
a public key, that document could have only been signed by the holder of
the corresponding private key. Can this identify the originator of the
document with enough assurance that one can accept a digital signature
replacement for a binding hand-written signature? A reasonable level of
trust must exist before electronic commerce becomes feasible.
This talk introduces cryptography with a focus on public key cryptography
and its use in digital signature. The talk examines the X.509 public key
certificate and the trust relationships that can be constructed using it.
The concept of public key infrastructure (PKI) is introduced including
certification authority (CA), revocation technologies, and repository.
The X.509 attribute certificate and its use in authorization is also
described.
Topics Covered :
This tutorial covers
-
encryption and hash algorithms
-
public cryptography
-
certificates (an electronic proof of identity and/or attributes defined
in the standard X.509)
-
trust relationships that can be constructed using them
It describes the public key infrastructure (PKI) that must be put in place
to support that trust, e.g. certification authorities.
TARGET AUDIENCE
The tutorial does not assume any understanding of cryptography. It covers
the basics as well as the more elaborate uses of the technology but will
not cover the mathematics nor go into detailed, e.g. ASN.1, descriptions
of the protocol or implemetation. Its intended audience is technical and
managerial individuals who wish to understand the concepts, issues, and
uses of digital signatures, particularily in its application to electronic
commerce.

Hoyt Kesterson is a Fellow at Bull Worldwide Information Systems in Phoenix,
Arizona
Hoyt.Kesterson@bull.com
ABSTRACT
This talk examines digital signature activity in three areas-
-
The infrastructure
-
How digital signatures are being used
-
National and international legislative activities.
The IETF's Public Key Infrastructure (PKIX) standard is described as well
as the specific approaches of the credit card and EDI domains. Some of
the uses of this technology are described, e.g. Netscape and Microsoft
browsers, VPNs, applet integrity, watermarks, secure email, smartcards,
EDI, and the Secure Electronic Transaction (SET) standard defined by the
VISA/Mastercard consortium. The legal issues of accepting documents and
transactions signed with a digital signature are discussed along with a
review of international, national, and state activity. The American Bar
Association's Digital Signature Guidelines and ongoing work on the certification
of CAs is also described.
Topics Covered :
-
IETF PKIX
-
Legal issues
-
Secure Electronic Transaction (SET) standard
-
Netscape and Microsoft browsers and applet integrity.
Important ancillary subjects are also described, e.g. authentication, confidentiality,
key recovery, integrity, non-repudiation, smartcards, import and export
regulations, system security, and general security issues such as vulnerabilities,
threats, countermeasures, and policy.
TARGET AUDIENCE
The tutorial assume some level of understanding of the material covered
in tutorial 3, "DIGITAL SIGNATURES - WHOM DO YOU
TRUST :The Technology and The Standard". Its intended audience is technical
and managerial individuals who wish to understand the concepts, issues,
and uses of digital signatures, particularily in its application to electronic
commerce.

Tutorial 5: MORNING
Title: Mobility Management in Mobile IP
Instructors:
Sandeep K. S. Gupta
Pradip K. Srimani
Colorado State University
srimani@CS.ColoState.Edu
ABSTRACT
In the past decade there has been an exponential growth in the use
of the Internet, portable computers, and wireless telephony.
It is expected that this growth will continue in the coming years.
Currently, to access Internet, we need to connect our computer to some
fixed point (home, office, library, school etc.). Increasing variety
of wireless devices like PDAs, digital cellular phones, or handhelds
calls for IP connectivity on the fly. Possibilities and potentials of
such mobile computing are enormous.
The most important obstacle in realizing mobile internetworking
is the way Internet Protocol (IP) operates - it essentially depends
on the IP addresses, that are assigned to fixed stationary physical
locations. Any solution for supporting mobility in the Internet is
constrained by the requirement of inter-operability with existing
Internet infrastructure and networking applications. Further, the
solution should be scalable to support increasing population of mobile
users and independent of the wireless hardware technology to enable
widespread use. Mobile IP is a standard that allows the user to have
a mobile IP address much like a cellular phone number. The purpose
of this tutorial is to provide an overview of the problems caused
by mobility and to describe in detail how these problems are overcome
by Mobile IP.
Topics Covered :
The tutorial will begin with general problem of mobility management
and packet routing to mobile hosts in a large internetwork. We will
then describe in detail the IETF Mobile IP protocol. This will
include basic protocol architecture, agent discovery protocol, registration
with foreign agent, registration authentication, and packet tunneling.
This will be followed by presentation on packet delivery optimization
techniques such as location caching.
TARGET AUDIENCE
Engineers, scientists, software developers, system analysts, network
users and designers, project managers, faculty members, graduate and
undergraduate students, who are interested in knowing how seamless
Internet connectivity can be provided to their mobile wireless devices.

Title: Mobile ATM: Goals, Challenges, and Emerging Solutions
Instructors:
Sandeep K. S. Gupta
Pradip K. Srimani

srimani@CS.ColoState.Edu
ABSTRACT
In the past several years we have experienced phenomenal growth in
mobile voice communications (cellular telephony) and the expectation
for the coming years are to provide customers capability to access,
process, visualize and distribute multimedia information anywhere
anytime on demand. In order to deliver audio and video data seamlessly
to mobile stations world-wide (with high quality), it is essential to
extend existing B-ISDN and Internet technologies to accommodate wireless
communication. There are currently several Wireless and Mobile ATM
(Asynchronous Transfer Mode) proposals on how to extend the ATM standard
to support wireless links and to provide seamless widearea mobility
of end-points.
There are many technical challenges to be solved before we can realize
the dream. Problems associated with implementing Mobile ATM consist
of standardization of radio frequency spectrum, design of new efficient
access methods, suitable location management schemes to track mobile
terminals, appropriate hand-off mechanisms and the likes. The purpose
of the present tutorial is to provide an overview of the user expectations,
associated problems and the proposed solutions. The participant would
be able to appreciate what has been done so far towards achieving
the goals and what still needs be done.
Topics Covered :
The tutorial will deal with mobile and wireless ATM. First we will
briefly present the wireless ATM specification which deals with the
medium access control, data-link c control and radio resource control.
We will then describe in detail the support for mobility management
in ATM. Extensions to existing specifications for location management,
hand-off, routing, and traffic management will be presented. This
would include topics such as baseline architecture specification,
integrated architecture model, hand-off signaling, integrated location
management scheme, external location management, connection rerouting,
and route optimization.
TARGET AUDIENCE
Engineers, scientists, software developers, system analysts, network
users and designers, project managers, faculty members, graduate and
undergraduate students, who are interested in knowing how seamless
Internet connectivity can be provided to their mobile wireless devices
running multimedia applications.
