1. A method for independently encrypting channels of data in a transaction, comprising:
encryption of a first data channel in the transaction using a first security association; encryption of a second data channel in the transaction using a second security association; encryption of an arbitrary number of additional data channels contained within the transaction using a unique security association for each channel, wherein the first data channel consists of point-to-point control data and the second data channel consists of end-to-end content data.
