A process for managing encrypted group communication according to a single security association (SA) for network traffic from a sender includes receiving a request for an encrypted communication among a plurality of network devices. A common decryption key and a common security parameters index (SPI) are provided to each of the network devices participating in the communication. The common security parameters index facilitates locating, in respective databases associated with each of the network devices, security association information that is associated with the common security association. Information is encrypted based on the common security association, and unicasted to each of the network devices. In an embodiment, the common security parameters index provided to each network device is established by the sender. For example, the SPI is established by a conference server and sent to each device participating in a voice conference.
