【摘要】：為解決當前車聯(lián)網(wǎng)中匿名認證的效率問題,利用橢圓曲線上的雙線性對的性質(zhì),提出一種批量匿名認證方案。通過路側(cè)單元節(jié)點(RSU)與車輛共同生成簽名,有效減輕了VANET認證中心的負擔進而提高認證效率,并且增加了攻擊者提取密鑰的難度,并在隨機預(yù)言模型中給出其安全性證明。分析表明,該方案能夠滿足多種安全需求,計算開銷明顯降低,認證效率得到有效提高。因此,該方案在計算性能受限的物聯(lián)網(wǎng)(Io T,Internet of things)環(huán)境中,有著重要的理論意義與應(yīng)用價值。
[Abstract]:In order to solve the efficiency problem of anonymous authentication in vehicle networking, a batch anonymous authentication scheme is proposed by using the properties of bilinear pairs on elliptic curves. The signature is generated by the road side unit node (RSUU) and the vehicle, which can effectively reduce the burden of VANET authentication center and improve the authentication efficiency. It also makes it more difficult for the attacker to extract the key, and the security proof is given in the random prophecy model. The analysis shows that the proposed scheme can meet various security requirements, reduce computing overhead and improve the efficiency of authentication. Therefore, this scheme has important theoretical significance and application value in the Internet of things (IOT) environment with limited computing performance.
