摘要
分析了卫星网络的通信特点,提出一种基于身份加密体制的安全密钥分发方法,用于解决在卫星网络中基于身份加密体制的密钥托管问题。该方法将密钥生成中心的功能进行划分,并将划分后的子功能分别由不同实体完成,网络结点通过与不同实体交互计算出私钥,防止单个密钥生成中心获取网络结点的私钥。安全性分析和仿真分析表明,该方法具有良好的安全性,在卫星网络中具有较高运行效率。
The communication characteristics of satellite networks is analyzed. A new secure key issuing method based on identity based encryption （IBE） is proposed to solve the IBE key escrow problem in satellite networks. It divides the function of key generate center into parts. The divided sub-functions are completed by different entities in the system. This scheme solves the problem of key escrow and prevents the individual key generating center to acquire the private keys of network nodes. The analysis shows that the scheme can provide good security and high efficiency for space information networks.
