Abstract

A wireless device supports roaming to a second access point if signal strength falls below a threshold or a connection is disrupted. The wireless device generates nonce values used for encryption and/or to protect against a replay attack. The nonce values a generated according to rules designed to minimize nonce reuse after roaming within a mobility domain. The wireless device may also be configured to generate encryption keys with a device of the mobility domain before a connection is established. The encryption keys are used after roaming to encrypt the earliest data frames sent after the roam.
