Mobile payment security card based on distributed key 基于分布式密钥的移动支付安全卡
Dynamic distributed key management in a hierarchy 动态分布式层次密钥管理
The process of storing, managing or distributing keys to authorised parties 贮存、管理或分发密码匙给获授权各方的程序。
A security facility for the purpose of generating and distributing key in electrical form 为以电子形式产生和分发密码匙而设的保安设施。
And we mainly focus on the distributed key management framework : igkmp and lolus, the rekeying protocol based on key tree, and periodical rekeying strategies 其中重点讨论了目前流行的组播密钥管理框架,密钥树,分隙密钥更新方案。
Security protocols take charge of distributing keys and authenticating identity . once there is a flaw in a security protocol itself, the security of communication would face danger 安全协议负责密钥分发和身份认证,一旦其自身出现漏洞,那么将会对通信的安全造成威胁。
It is difficult to set up a center to distribute key because of its instant, dynamically changing topology, so the security of wireless ad-hoc networks has become a hot spot 由于ad-hoc网络的临时、动态的拓扑结构,难以使用密钥分配中心分配密钥,从而使得其安全性备受关注。
Several kinds of trust-based key pre-distribution protocols and random pre-distribution protocols which are classic in wsn are recited, and tinyos system is used simulating network communication to distribute keys 作者论述了目前比较典型的几类初始信任的密钥预分配协议和随机密钥预分配协议,并使用tinyos系统模拟实现密钥分配过程。
The algorithm has much more benefit over exist ones . fourthly, the 3gpp ims specifications introduce the many-to-many relation-ship between pui and pvi, it ’ s has an obvious influece on the performance of distributed sip systems and the result under different distributed key is assessed 4、研究了ims用户身份标识与鉴权卡号之间的多对多关系,分析了其对分布式sip处理系统的影响及在不同分布关键字条件下的系统性能。
