Leung Department of Electrical and Computer Engineering Faculty of Applied Sciences University of British Columbia 2356 Main Mall Vancouver BC Canada V6T1Z4 Received 2 October 2005 Revised 18 April 2006 Accepted 21 April 2006 This paper presents multiple-channel SSL MC-SSL an architecture and protocol for protecting client-server communications. In contrast to SSL which provides a single end-to-end secure channel MC-SSL enables applications to employ multiple channels each with its own cipher suite and data-flow direction. Our approach also allows for several partially trusted application proxies. The main advantages of MC-SSL over SSL are a support for end-to-end security in the presence of partially trusted proxies and b selective data protection for achieving computational efficiency important to resource-constrained clients and heavily loaded servers.

INTRODUCTION While the Internet is advancing from wireline to wireless networks a growing number of handheld devices such as cellular phones PDAs and palmtops can access Internet applications for example Web e-mail multimedia and so forth. Securing client-server communication between resource-constrained handheld devices and heavily loaded Internet servers has been a challenge. A handheld device has many more constraints than an ordinary computer in terms of power processor memory display and other resources. The access channels of handheld devices range from 2 G G 3 G cellular networks wireless LAN
