摘要：Global connectivity provided praxis for data transactions. Data or information is available in different forms like text, image, audio, video etc. Security mechanisms are aimed at security algorithms with an assumption that the information is in bit stream. Human understanding in practice deals with information other than bit stream. In the transaction process of information, users allow human understandable format of data. A simple case of text data may deal with various types of scripts represented in multiple combinations of bit streams. Transformation of the basic characteristics that are embodied in the script is an interesting area to be explored in security models. Decipherment problems related to message equivocation is mainly dependent on the statistical complexity of script. The present work is aimed at analyzing the basic characteristics of a script in the form of frequency distribution of character code points. The proposed model is evaluated on Telugu script as a case study with a comparison on Latin text. The evaluation is limited to 8-bit and 16-bit key sizes.
