Secure Multicast Transmission

This white paper discusses the encryption of multicast data traffic at Layer 2 to provide secure data transmission through high-speed networks. Thales CN series encryptors are devices that secure information transmitted at wire speeds across wide area Ethernet services. Encrypting multicast traffic is difficult because of the nature of the data flow. This paper describes how multicast traffic can be transmitted simply and securely by encrypting at Layer 2 in the OSI model.
