Abstract
A method includes receiving data at a first wireless node in a wireless network, where the data is associated with an industrial control and automation system. The method also includes decrypting the received data using a first encryption key to produce decrypted data and encrypting the decrypted data using a second encryption key to produce encrypted data. The method further includes communicating the encrypted data to at least a second wireless node in the wireless network. Another method includes generating first data at a first wireless node in a wireless network, where the data is associated with an industrial control and automation system. The other method also includes encrypting the first data using an encryption key and transmitting the first data to multiple second wireless nodes in the wireless network, where the second wireless nodes are capable of using the same encryption key to decrypt the first data.
