Security Enhancement of English Text using PRATHALA TABLE of ALPHANUMERALS

PRATHALA TABLE of ALPHANUMERALS is a 62 x 62 matrix table developed by the authors for cryptographic purpose. In this paper a newly developed table of ALPHANUMERALS is proposed using Vigenere cipher logic. About (62!)62 tables can be generated. Each table is a 62 x 62 matrix. At any point of time any one of the tables can be used for encryption. The same table is to be regenerated and used for decryption. Experiments conducted shows that PRATHALA TABLE of ALPHANUMERALS method is much more secure than Vigenere Table Method.
