Outsourcing paradigm has become a hot research topic in the cryptography community, where computation workloads can be outsourced to cloud servers by the resource-constrained devices, such as RFID tags. The computation of bilinear pairings is the most expensive operation in pairing-based cryptographic primitives. In this paper, we present two new algorithms for secure outsourcing the computation of bilinear pairings. One is secure in the OMTUP model. The other, which provides flexible checkability, is in the TUP model. Compared with the state-of-the-art algorithms, our proposal is more efficient.
