Abstract
Delegating or outsourcing of computation is a prominent feature of cloud computing. It can be made secure through fully homomorphic encryption which allows processing of encrypted data. Verifiability of results is essential where a service-provider cannot be trusted. Since it is mostly used by lightweight devices, so mechanisms are required to verify the results of computations efficiently. In this paper protocols for VDoC are discussed, which focus on verification of aspects of computation other than the results, namely depth and complexity of delegated function which are useful when a user wants to verify amount charged by the service provider. A symmetric-key homomorphic scheme for encryption is being used. The protocols have a real-world relevance and the runtime are small enough for practical feasibility.
