【摘要】：使用無線信道的物理層信息在無線設(shè)備間生成私密密鑰用于確保移動環(huán)境的安全,如今受到了廣泛關(guān)注。然而在現(xiàn)實(shí)環(huán)境中,在多個設(shè)備之間生成群密鑰以確保群安全通信的問題仍然存在挑戰(zhàn)。針對無線網(wǎng)絡(luò)星型拓?fù)浣Y(jié)構(gòu),提出一種基于中心節(jié)點(diǎn)成對生成策略的群密鑰產(chǎn)生方案。相比于文獻(xiàn)中提出的利用群內(nèi)節(jié)點(diǎn)間的接收信號強(qiáng)度差分實(shí)現(xiàn)提取群密鑰的方案,詳細(xì)分析了它們各自能實(shí)現(xiàn)的群密鑰容量并給出了數(shù)值計算結(jié)果。分析表明,提出的基于成對生成策略的群密鑰產(chǎn)生方法在密鑰率方面優(yōu)于文獻(xiàn)中的差分提取方案。
[Abstract]:The use of physical layer information of wireless channels to generate private keys between wireless devices to ensure the security of mobile environments has received widespread attention. The problem of generating group keys between multiple devices to ensure group secure communication remains a challenge. A group key generation scheme based on the pairwise generation strategy of central nodes is proposed. The group key capacity which they can realize is analyzed in detail and the numerical results are given. The results show that the proposed group key generation method based on pairwise generation strategy is superior to the difference extraction scheme in terms of key rate.
