| Research Abstract |
We have proposed an efficient storage network system using fast secret sharing schemes. The proposed system can compute shares from the secret and recover the secret efficiently only using XOR operations. Furthermore, we have proposed secret sharing schemes for general access structures. For any access structure the proposed schemes are more efficient than general secret sharing schemes which are based on minimal access structures.
