New Data Encryption Algorithm and its Implementation for Online User Authentication

Most of the encryption algorithms used today generate huge cipher messages as well as long encryption keys. These approaches require time and are computationally intensive. In this paper we introduce two operators, represented as mathematical models called Pentor and Ultra Pentor. These operators can be easily generated out of any number and can be used for encryption purposes. The strength of the cryptosystem proposed here lies in the irreversible property that these two operators have during the authentication process. Once the operators have been generated, it is extremely burdensome to find the numbers out of which these operators have been generated. This irreversible property has been used for creation of online authentication scheme that uses a genuine three step encryption algorithm. The strength of the proposed cryptosystem disserts the possible applications in online authentication systems.
