Title: Digital Signatures - Whom do you trust?   The technology and the standard

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 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.

ABSTRACT

This talk examines digital signature activity in three areas- 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 :

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

 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.

 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.
