JSE_V1_N4_RP8 Vinu V. Das Journal on Software Engineering 2230 – 7168 1 4 81 84 Quadratic cryptography, Integrity algorithm, Residuosity, Quadratic residue encryption, Quadratic residue problem This paper presents a new and efficient algorithm that provides a high degree of integrity for the packets, which are encrypted using Quadratic Residue Cryptography. This standard, evolved from the base of Quadratic Residuosity Problem, provides security for the bit in the information super highway. Even though a number of Quadratic Residue encryption techniques are available, there is no algorithm for ensuring its integrity. Quadratic Residue Integrity Standard will nullify the same.
