| contents | Pseudonym change strategy based on the reputation of the neighbouring vehicles in VANETs Luz Marina Santos-Jaimes Edson dos Santos Moreira Ingeniería privacy reputation pseudonym change Vehicular network Pseudonym change schemes have been studied in VANETs to guarantee the property of untraceability of the vehicles. This paper proposes a new condition based on the assumption that if there are no malicious vehicles around when a synchronous change triggers, there is no risk of tracking, and the pseudonym change defers until a time threshold. Thus, our proposal based on a synchronous strategy to increase the anonymity set, adds to the change condition, the checking of the reputation status of the neighbouring vehicles. The reputation status is the result of discretizing the reputation score of the vehicles and it is part of the periodically broadcasted beacon messages. The proposal was evaluated through experiments using a simulated scenario of a real map. The results showed an optimization in the use of pseudonyms maintaining similar anonymity levels with other schemes. 2019 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49663345018 https://www.redalyc.org/journal/496/49663345018/ https://www.redalyc.org/journal/496/49663345018/html/ https://www.redalyc.org/journal/496/49663345018/49663345018.epub https://www.redalyc.org/journal/496/49663345018/movil 10.15446/dyna.v86n211.75602 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.211 Vol.86 |
