Research on quantum signature on GHZ-like state for digital home network
MA Hong-yan · Jisuanji gongcheng yu sheji · 2013
Information security of smart appliance is key to digital home network,but the existing security protocol is based on the symmetric-key encipherment and asymmetric-key encipherment,this protocol has safe hidden troubles due to the characteristics of channel.Quantum signature protocol on GHZ-like state for digital home network is designed,which shares GHZ-like state with smart use appliance,smart terminal appliance and home gateway.Smart use appliance sends message to smart terminal appliance.It solves the problem of identification of smart use appliance by home gateway,the security of data transmission is guaranteed by quantum cryptography.The protocol has the merits of unconditionally security and lower complexity.
