高效強安全的多策略虛擬企業(yè)交互認證方案
發(fā)布時間：2019-05-16 06:59
【摘要】：成員企業(yè)間的信任交互是虛擬企業(yè)所有安全問題的基礎(chǔ)和前提�，F(xiàn)有的虛擬企業(yè)交互認證方案都沒有定期更新和多策略認證功能,且有些不能抵抗合謀攻擊,有些不具備身份可追查性,有些將盟主放在主導(dǎo)地位,安全性較差。為此,提出了一個多策略、可定期更新的高效強安全虛擬企業(yè)動態(tài)認證方案,進行了安全性分析和效率對比。方案可實現(xiàn)證書的定期更新;成員加入或退出時無需改變?nèi)核借�、其他成員的密鑰和證書,減小了方案實施的代價;實現(xiàn)了多策略證書頒發(fā),更能適應(yīng)不同成員區(qū)別認證的需求;方案還具有抗合謀攻擊性、簽名成員身份可追查性、部分簽名可驗證性等多種安全優(yōu)勢。仿真實驗表明,相對于其他方案,該方案計算效率更高。
[Abstract]:Trust interaction among member enterprises is the basis and premise of all security problems in virtual enterprises. The existing virtual enterprise interactive authentication schemes do not have regular updates and multi-policy authentication functions, and some can not resist collusion attacks, some do not have identity traceability, some put the leader in the dominant position, and the security is poor. Therefore, a dynamic authentication scheme of efficient and strong security virtual enterprise is proposed, which can be updated periodically, and the security analysis and efficiency comparison are carried out. The scheme can realize the periodic update of the certificate, the members do not need to change the group private key when they join or exit, and the keys and certificates of other members reduce the cost of the implementation of the scheme. The scheme also has many security advantages, such as anti-collusion attack, traceability of signature membership, verifiability of partial signature, etc. The scheme also has many security advantages, such as anti-collusion attack, traceability of signature membership, verifiability of partial signature and so on. The simulation results show that the proposed scheme is more efficient than other schemes.
