Two Anonymous Cooperative Caching Schemes in Mobile Ad Hoc Networks

Mobile ad hoc networks have been extensively studied in recent years due to its potential applications in civilian and military environments. Cooperative caching could be employed to improve data accessibility and reduce data access cost in mobile ad hoc networks. In this paper, we present two secure and anonymous cooperative caching schemes based on onion message and pseudonym-based encryption, respectively. The proposed schemes can not only protect the privacy of nodes and routes, but also can resist both passive and active attacks.
