Predominantly large distributed networks currently provide support for group oriented protocols and applications Regardless of the type of distributed network there is a need to provide communication privacy and data integrity to the information exchange amongst the group members This paper introduces a protocol named Authentication based Secure Communication Plane adopts the commutative RSA algorithm to maintain data integrity The proposed protocol not only eliminates the overheads resulting from key distribution and key compromise attacks but also provide for information security in the presence of colluded group members Radio Frequency Identification tags is used for group member identification The RACP protocol is compared with the RFID extended Secure Lock group communication protocol and its efficiency in terms of the computational complexity involved is discussed in this pape
