Cascaded Encryption Scheme (CES) for Robust Content Security Over Internet Networks

In an age when information exchange has been made more mobile by the advent and advances in internet technology, information security is assuming a worrisome dimension. Hacking, phishing, eavesdropping, scamming and a host of other vices have become the order of the day on communication channels. This research addresses the problem of data security on multimedia systems by proposing a cascaded approach to text encryption while in transit. The objective is to protect message content over public network by hybridizing and combining encryption algorithms in a cascaded format in a single document thus making breaking the codes more difficult for intruders. To counter this threats, new security technologies are required that persistently protect content throughout its lifetime. Conditional Access Systems (CAS) has been used to protect content delivered over cables. In [16] we presented a technique for protecting digital content on passing through Internet intermediaries. This present effort proposes a methodology that divides messages to be encrypted into packets coded using different encryption algorithm. Annotation techniques are implemented as pointers to sections within the documents to aid decryption. Index Terms Cascaded, Annotation, Access, Encryption, Protection, Internet, Intermediaries.
