Wireless Public Key Infrastructure for Mobile Phones

Mobile devices play an important role in the wireless network environment for providingdifferent services over internet. The business transactions over wireless electronic devices are not secureand hence the messages are prone to be intercepted and modified by an intruder. So, devices supportingwireless internet must be guaranteed at the same level of security as the wired network. PKI (Public KeyInfrastructure) used in the wired environment is not suitable for wireless environment because of the lesspowerful processor and small memory. This arises a need for the development of a Wireless Public KeyInfrastructure (WPKI) that provides the similar security level as the wired PKI suitable for mobile phone.In this paper, a discussion of public key infrastructure and an experimental set up for Wireless Public keyInfrastructure for mobile phones are made.
