Improved ECC hybrid Encryption Scheme for Security Analysis of a Single Sign-On Mechanism in Distributed Computer Networks

Single sign-on (SSO) is definitely an authentication mechanism that enables any legal user which has a one credential being authenticated by means of many distributed computer networks. Recently Chang and Lee proposed the latest SSO structure in addition to state their safety measures by providing well-organized safety measures quarrels. In another attack, an outsider without any credential might be able to enjoy network services freely by means of impersonating virtually any legal user or a nonexistent user. Most of us discover the actual weaknesses of their safety measure exactly why attacks are generally probable in opposition to their SSO structure. Our attacks also apply at a different SSO structure proposed by means of Hsu in addition to Chuang, which in turn influenced the planning from the Chang–Lee structure. In this proposed do the job many of us use Elliptic Challenge Cryptography (ECC) regarding higher efficiency together with small key dimensions a good choice for safety measures quarrels which has restricted strength. In the proposed system applying ECC the actual cryptographic procedures will be performed together with a lot fewer processor cycles operation can be carried out faster and providing well-organized security arguments in distributed computer network.
