A Secure Authentication Scheme for Teleservices Using Multi-Server Architecture

The telecommunications industry covers various sectors and services such as broadband, telecom equipment, infrastructure, telephone service providers, mobile virtual network operators, 5G, the white space spectrum. Smart Cards may be chosen one of best mechanisms for authorized access to these in sector. Recently, Jin Kwak proposed a scheme based on dynamic identity authentication purposes, mentioning that does not suffer from security breaches attacks. This paper illustrates Kwak’s technique finds it violates purpose contrary his claim. Due design issue scheme, an adversary guess password polynomial time impersonate legal user. Furthermore, other attacks, including replay attack, are also possible, stamp was protected this scheme. We propose improved version is free guessing by hiding user attacks using securely. results mentioned performance efficiency comparison show faster than many existing schemes.
