Security is an important concern for many Vehicular Ad hoc Network (VANET) applications. One particular serious attack, known as Sybil attack, against ad hoc networks involves an attacker illegitimately claiming multiple identities. In this paper, we present a simple security scheme, based on the difference in movement patterns of Sybil nodes and normal(More)
Vehicular Ad Hoc Network (VANET) is vulnerable to many security threats. One severe attack is Sybil attack, in which a malicious node forges a large number of fake identities in order to disrupt the proper functioning of VANET applications. In this paper, a distributed and robust approach is presented to defend against Sybil attack. Proposed scheme(More)
Mobile Cloud Computing (MCC) has become an important research area due to rapid growth of mobile applications and emergence of cloud computing. MCC refers to integration of cloud computing into a mobile environment. Cloud providers (e.g. Google, Amazon, and Salesforce) support mobile users by providing the required infrastructure (e.g. servers, networks,(More)
Security issues in Vehicular Ad-Hoc Networks (VANETs) are important because of its diverse implications in safety related and congestion avoidance applications. A critical security problem in VANET is injection of false data, i.e. an attacker propagates false information to disrupt the behavior of drivers. Most of VANET applications are time critical and(More)
