abstract = {Mobile Internet access is becoming more and more pervasive in the new 4G scenarios, where WiMAX is to play a crucial role. WiMax has advantages when considering both energy consumption and bandwidth, when compared with HSDPA and LTE. However, we have found some limitations in IEEE 802.16 security support, which may limit authentication and authorization mechanisms for ubiquitous service development. In this article we analyze weaknesses and vulnerabilities we have found in WiMAX security. WiMax, with the adequate identity management support, could be invaluable for developing new pervasive computing services. We propose the introduction of identity management in WiMAX, as a pervious step to the definition of identity aware WiMax personalization of pervasive computing services.},

abstract = {Privacy is a very complex and subjective concept with different meaning to different people. The meaning depends on the context. Moreover, privacy is close to the user information and thus, present in any ubiquitous computing scenario. In the context of identity management (IdM), privacy is gaining more importance since IdM systems deal with services that requires sharing attributes belonging to users’ identity with different entities across domains. Consequently, privacy is a fundamental aspect to be addressed by IdM to protect the exchange of user attributes between services and identity providers across different networks and security domains in pervasive computing. However, problems such as the effective revocation consent, have not been fully addressed. Furthermore, privacy depends heavily on users and applications requiring some degree of flexibility. This paper analyzes the main current identity models, as well as the privacy support presented by the identity management frameworks. After the main limitations are identified, we propose a delegation protocol for the SAML standard in order to enhance the revocation consent within healthcare scenarios.},
