We obtain publicly verifiable Succinct Non-Interactive Arguments (SNARGs) for arbitrary deterministic computations and bounded space non-deterministic computation from well-studied group-based assumptions. In particular, assuming the sub-exponential hardness of the Decisional Diffie-Hellman (DDH) and Quadratic Residuosity (QR) assumptions, we obtain the following results, where n denotes the length of the instance: 1. A SNARG for any language that can be decided in non-deterministic time T and space S with communication complexity and verifier runtime(n+S)·T^{o(1)}. 2. A SNARG for any language that can be decided in deterministic time T with communication complexity n·T^{o(1)} and verifier runtime n·T^{o(1)}.
