| Abstract: | Secure Multi-party Computation（SMC） about which people have got some research findings at home and abroad has been a research focus in international cryptographic community recently，and this paper proposes a new protocol for the inverse of n×n matrices by using Oblivious Transfer 1 out of p protocol in the secure two-party computation environment.The protocol can be used to solve the problem securely and more efficiently.Then gives a new protocol for secure two-party linear system of equations based on it. |

| Keywords: | secure multi-party computation protocols the inverse of n×n matrix Oblivious Transfer 1 out of p protocol |
