Abstract:
Mathematical techniques for encrypting and decrypting data are known as cryptography. With the use of cryptography, private data may be securely stored or sent across unsecured networks, ensuring that no one else can access it. Cryptanalysis is the study of deciphering encrypted messages, in contrast to cryptography which is concerned with data security. Analytical thinking, mathematical tool application, and pattern identification are all fascinating components of classical cryptanalysis. Proposing a model for authentication and confidentiality utilizing a mix of symmetric and public cryptosystems, as well as a novel cryptographic approach based on the special matrix known as the Hilbert matrix, are the aims of the proposed study. In addition, the idea of digital enveloping with a session key is expanded to shared key cryptosystems. Using the Hilbert matrix cryptosystem, this study develops a method for shared key encryption.
