• Security in mobile clouds: Although an issue of paramount importance, little research has been carried out in this regard. Users would need to feel confident when offloading their jobs to other surrogates such that their privacy would not be violated. Although many of the reviewed frameworks mention the need for security and trust, very few of them have actually implemented it and have left the implementation for future directions. As discussed in [23], consider a mobile user offloading a language translation program to a surrogate server, and a malicious VM manager distorting the translation with the intention of sabotaging the user’s business transaction. As suggested in [23], avenues towards this need to be examined, possibly with trust establishment methods or reputation-based trust.
