Abstract: Currently, cloud computing is very appealing because it allows the user to outsource his data so it can later be accessed from multiple devices.The user can also delegate to the cloud computing service provider some, possibly complex, operations on the outsourced data.Since this service provider may not always be trusted, it is necessary to not only preserve the privacy but also to enforce the authenticity of the outsourced data.Lately, a lot of work was put on solving the first problem, specially after the introduction of the first Fully Homomorphic Encryption scheme.In this work we will focus on the latter, namely on the use of Homomorphic Message Authentication primitives.We will evaluate the current available solutions, their functionality and their security.Finally, we will provide an implementation of one of these schemes in order to verify if they are indeed practical.To my supervisor, Professor Manuel Bernardo Barbosa, for the great opportunity, all the guidance and all the suggestions that lead me here, many thanks.To Professor Dario Catalano, for receiving me in Catania and for all the precious help and advises given during my stay.A special
