WTML only provides security between the wireless device and the WAP gateway, i.e. the protocol addresses security issues at the transaction layer, but this only covers confidentiality and message integrity. This means that two, tightly linked security issues are not resolved: authentication of both sender and receiver, and non-repudiation of the transaction. It is clear that m-commerce applications cannot be implemented until the WAP Forum addresses these issues. However, CMG has decided not to wait for a new version of the specification and increased security has already been introduced into the companys WAP Service BrokerTM product.

"The added-value security capabilities that are provided by Release 1.1 of the WAP Service BrokerTM enable our customers to enter the electronic commerce market now. CMG can provide a smooth growth path to the end-to-end security capabilities provided by the WAP Forums Wireless Identity Module and Wireless Public Key Infrastructure initiatives," said Geert Kolthof, CMGs Vice-President Mobile Internet Products.

Client authentication is provided by means of Calling Line Identity, in combination with user name and password validation. This is equivalent to providing the senders unique identity, since the calling line identity is virtually impossible to duplicate. The WAP Service BrokerTM registers every event passing through the gateway. Logs are generated for all transactions between the wireless device and the WAP Service BrokerTM, as well as the broker and the banking and e-commerce applications in the Internet or Intranet domains. The owner of the WAP Service BrokerTM can therefore confirm the completion of the transaction, which means that it cannot be repudiated at a later date.
