Reducing PKI related network load in bandwidth constrained environments

When adding PKI to bandwidth constrained environments, it is necessary to optimize the information sent with any given message so as to consume the least amount of bandwidth possible. One of the components of a PKI transaction that increases the size of the message is the transmission of the X.509 certificate. This paper introduces a way to reduce the amount of network traffic due to PKI by proposing a methodology whereby the X.509 certificate does not need to be transmitted with every message, thereby reducing the size of the message that is transmitted.
