Wireless Application Protocol (WAP) has an issue commonly referred to as the WAP gap. You can secure client/server synchronization with transport-layer security (TLS) to prevent WAP gap compromises.
TLS takes advantage of digital certificates and public-key cryptography to enable encryption, tamper detection, and certificate-based authentication for entity state replication environments.
A WAP gap breaks end-to-end communication data privacy. TLS encryption closes the WAP gap to ensure the synchronization stream is protected and secure. This diagram shows a traditional SSL synchronization stream passing through the WAP gap, where one SSL session encrypts the device-to-Relay Server stream and the other encrypts the Relay Server-to-SAP Mobile Server stream.
Once you enable TLS to encrypt the entire synchronization data stream, you avoid passing unencrypted data through this WAP gap.
