基于身份的密码系统可以在资源受限的移动的ad hoc网络中建立密钥分配和管理体系结构，因为它不受证书管理问题的影响。基于一种轻量级的椭圆曲线密码体制，提出了一种适用于移动的ad hoc网络的基于身份的分布式密钥分配协议。在该协议中，我们使用秘密共享，建立一个虚拟私钥生成器，它计算用户的一部分密钥并通过公共信道发送给用户，而另一部分密钥由用户生成。因此，用户的秘密密钥由虚拟权威机构和用户协作生成。每一个都有关于用户密钥的一半秘密信息。因此，不存在密钥分发问题。此外，用户的秘密密钥只有用户自己知道，因此不存在密钥托管。
An identity-based cryptosystem can make a special contribution to building key distribution and management architectures in resource-constrained mobile ad hoc networks since it does not suffer from certificate management problems. In this paper, based on a lightweight cryptosystem, elliptic curve cryptography (ECC), we propose an identity-based distributed key-distribution protocol for mobile ad hoc networks. In this protocol, using secret sharing, we build a virtual private key generator which calculates one part of a user’s secret key and sends it to the user via public channels, while, the other part of the secret key is generated by the user. So, the secret key of the user is generated collaboratively by the virtual authority and the user. Each has half of the secret information about the secret key of the user. Thus there is no secret key distribution problem. In addition, the user’s secret key is known only to the user itself, therefore there is no key escrow.
