The polygraphic substitution cipher is the primary cryptosystem (cryptsys) technique that has various advantages in sheltered key encryption (encryp). A substitute enhancement is an inescapable key that is essential for converting cipher text to plain text and it is not appropriate for cryptsys, a readable text comprising of nix. The unmasking of these works is to improve the assessment of polygraphic substitution crypsys to get the better of these complications. Examination of the preceding conclusions presented specifically usual polygraphic substitution cipher techniques that are not yet suitable without automation because there may be many chances of vulnerability. These techniques are especially vulnerable when identifying plaintext. These algorithms also have improved modification attributes and as an outcome, they are advance resistant likened to recognized plaintext attacks using automation systems. On the other hand, these enhanced polygraphic substitution cipher algorithms have a modulate matrices key problem which is rapidly solved by the system. Moreover, these algorithms are not appropriate for entirely null values for respective blocks of crypsys. In the present report, the evaluation of polygraphic substitution enhanced the advanced technique which applies to the singular key with an automation system. Expanding of the recommended system is substantiated via generated key matrix approaches that are relatively complex to recognize. The preceding exploration concentrated on a polygraphic substitution using a sharable or single key algorithm without an automation system. During the decoding of the encrypted text, there are raised vulnerabilities. This survey keeps accelerating the usage of the evaluated polygraphic substitution cipher to act in a comparative approach in evaluating the raised vulnerabilities conversely to the key matrix. In this research, an automation system has no issues to identifying the vulnerabilities.
