The current study is based on novel solution which deploy the security mechanism, more advance cryptography solution within distributed Network Protocol (DNP3) stack as a part of critical system (or SCADA) system). The Dynamic Cryptography Buffer (DCB) has been implemented that contains 56 from total size of Application Protocol Data Unit (APDU) bytes as a part of application layer of DNP3 protocol. The DCB contains several fields/sub-fields which have been used during implementation of cryptography algorithm and other information ( or detail) related with protocol security. During implementation with DNP3 protocol, the are dynamically stored after processing ( security deployment) within DCB, without affecting the total size of DNP3 protocol stack. This novel study gives new directions for SCADA or its protocols security deployment and enhancement.
