SAML Standard Optimization for Use on CoAP-Based Web Servers on Internet of Things

The use of web services has been increased by IoT technology development and increasing interoperability between objects. IoT web services Access control is a challenging problem in IoT environment. Many standards such as SAML has been proposed for authorization and access control in common web services, but it is not possible to use these standards in IoT web services, because IoT resources has constraints in network, memory and procces.In comparision of SAML standard, optimized SAML is more appropriate fot IoT Web services because of low memory usage and processing time and, consequently, the reduction of the time for providing access in IoT environments.
