Researchers often have access to a variety of different high-performance computer (HPC) systems in different administrative domains, possibly across a wide-area network. Consequently, the security infrastructure becomes an important component of an overlay metacomputer: a user-level aggregation of HPC systems. The Grid Security Infrastructure (GSI) uses a sophisticated approach based on proxies...

Due to the increasing number of service providers, the grouping of these providers following the federation concept and the use of the Single Sign On (SSO) concept are helping users to gain a transparent access to resources, without worrying about their locations. However, current industry and academic production only provide SSO in cases with homogeneous underlying security technology. This pa...

Browser-based Single Sign-On (SSO) protocols relieve the user from the burden of dealing with multiple credentials thereby improving the user experience and the security. In this paper we show that extreme care is required for specifying and implementing the prototypical browser-based SSO use case. We show that the main emerging SSO protocols, namely SAML SSO and OpenID, suffer from an authenti...

Single sign-on (SSO) is an emerging and more secure authentication mechanism that enables an authorized user with a single username/password to be authenticated by many service providers in a distributed network system. The existing technique used SSO scheme and it has achieved security by applying wellorganized security parameters and its improved scheme introduced Verifiable Encryption of Sig...

The generation of user credentials for system access coupled with the resulting rising security threats have led to the development of single sign-on (SSO) access control and multiple authentication technologies. This paper provides an overview of these authentication mechanisms, highlighting the current state in the marketplace and describing the key enabling technologies. The resulting analys...

. Perceived organizational support has been raised as work backbone of employee in the organization and the psychological contracts are also a set of promises that top managers give to support their employees. Therefore, violation of this contract not only involves depriving organizational support, but also reduces the employee's belongings. The main purpose of this paper was to examine the imp...

The research explores a strategic control model by the emphasis on the green approach based on Simons’ levers of control framework. Special consideration is paid for assessing how much green is the organization. The purpose of this paper is to design a strategic control model for Audit institute of social security organization of Iran. The data is gathered from social security organization and ...

The Single Sign-on technique (SSO) facilitates the management of authentication and authorization functions in a federation of servers providing access to protected resources. Different approaches to SSO exist, among them the XML-based Security Assertion Markup Language (SAML) standard, which has been used in applications such as intranet access within organizational domains. This paper focuses...
