Abstract
The need for delegating information arises when the data owner wants to have her data handled by an external party. If the external party is untrusted and data are confidential, delegation should be performed in a way that preserves security. Uses of delegation range from public administration to smart cards. In this paper, correctness and security requirements as well as protocols are specified for delegation of computing and data. A cryptographic solution to the secure delegation problem is described which provides data confidentiality and computation verifiability. Finally, an implementation allowing secure delegation of information over the Internet is briefly discussed.
