AbstractVehicular Ad-hoc Networks (VANETs) can improve the road safety by transmitting safety-critical messages such as beacons and emergency messages. IEEE 802.11p VANETs have adopted the carrier sense multiple access with collision avoidance (CSMA/CA) mechanism for the multiple access control. The 802.11p media access control (MAC) protocol, however, can not guarantee the reliability of broadcasting data, since the reception of transmitted messages are not acknowledged. Moreover, the backoff scheme of the 802.11p MAC utilizes a fixed-size contention window for safety message broadcasting, which causes high collision probabilities especially in dense environments. In order to improve such drawbacks, we propose a hybrid access method as follows: Nodes are equipped to reserve time slots for the next round of broadcasting, while unoccupied time slots are preserved for those which have emergency needs. In addition, implicit feedbacks are enabled for detecting collisions incurred during random channel accesses in preserved time slots. We devise a mathematical model which optimally controls the parameters of our scheme while minimizes the cost caused by idle channels and collisions. Extensive simulations show that our mechanism can remarkably improve the performance of VANETs in broadcasting of the safety messages.

Access control and Data confidentiality are key technology to ensure the security of system and to protect the privacy of the users. The modified Collaborative Trust Enhanced Security (CTES) model has an inbuilt access control mechanism for Kerberos protocol itself to enforce the access control policy directly into the Client system node. This paper explains the hybrid access control model with Role Based Access Control (RBAC) and Attribute Based Access Control (ABAC) for modified CTES framework through Kerberos protocol. Hence, it retains the concept of “role”, “group” and “attributes” for the user which are necessary to protect data privacy in the system. Data confidentiality for the stored data in Cloud is achieved by cryptographic techniques. Gnu Privacy Guard (GnuPG) based certificate is capable enough to verify the identity of the correspondent in information exchange as well as the information integrity. It is a strongest authentication technique where the user is asked to provide his/her digital ID for validation in the Server and enables Single sign-on services for Kerberos Authorization in modified CTES model. In this paper, it is proposed for a new Kerberos Authorization with Hybrid Access Control Model (KAHAC) for single-domain systems and multi-domain systems in Public Cloud based on roles, attributes, groups, access modes and the type of resources.
