In this paper, Secure Network Interface Card (SNIC) Architecture is proposed, to provide secure video communication without extra overhead on host processor of receiver. PROM based security model is developed & its integration with Network Interface is described. The approach adopted here to design SNIC, is based on remote reference passing. In this approach PROM is integrated to NIC to serve as security buffer where data values are to be placed at memory locations using some mathematical mapping which establishes relation between location reference and data. Sender generates respective location reference (at receiver's security buffer) corresponding to the each data byte of video stream. For reference creation, respective reverse mathematical mapping is used.
