Recently, XML is used to describe details of service and contents for various fields such as IPTV and digital broadcast services because of it's high readability and extensibility. TV-Anytime's schema and delivery protocol have been especially adopted as basic standards for them, and extended to include their own private functions. However, XML describes documents using text-based method, and this causes to create big documents rather than traditional methods. Therefore, many encoding algorithms have been proposed to reduce XML documents like EXI, BiM, GZIP and fast-info set etc. Although these algorithms shows efficient compression effects for XML documents, but they can't avoid fragmentation degradation during encapsulation steep. This paper proposes an efficient encapsulation scheme of TV-Anytime to avoid fragmentation degradation of encoding effect using common string tables.

“…Similarly, if a current address of a block is already stored in the table, this shows multiple calls. The PK is created at this time and stored in the binary image in a data section [19]. A fundamental block D is called upon by multiple blocks B, C, and F. The secret key of B is the hash value of block A, and the secret key of block C is the same.…”

Security threats such as viruses, worms, trojans and spyware affects the security and authentication of software codes, forcing software developers to build security schemes for better software protection. These software threats exploit the authenticated data of the software and confidentiality, integrity and accessibility is greatly affected by these software threats. A number of code security techniques like tamper resistant packaging, code obfuscation, register encoding etc have been developed which mainly concentrates on providing solutions for a particular type of threats and are vulnerable to code tampering and code injection by complicated attackers. Hence, code encryption technique has become an active area of research. This paper proposes a novel software protection code encryption scheme based on the index table. This approach uses a novel and efficient encryption technique called quasigroup encryption for encryption the indexed table. It provides least resemblance of the original data when encrypted. But, quasi group encryption is not efficient in diffusing the statistics of the plain text. This drawback can be overcome by using transforms. Hence, this approach uses chained Hadamard transforms and Number Theoretic Transforms to introduce diffusion along with the quasigroup transformation. The proposed approach is compared with the other encryption approaches and is observed to provide better results.
