Embodiment Construction

[0044] A kind of ZigBee security network that adopts public key key system NTRU, comprises the steps:

[0045] Step 1. Initialization process:

[0046] The initialization process is realized before networking. According to the NTRU public key cryptosystem, the system parameters that meet the NTRU establishment conditions are selected during system initialization, and the random function Random is constructed. G (m, R 1 , R 2 ,):

[0047] The NTRU cryptosystem relies on three parameters (N, p, q) and four polynomial sets L of polynomials with integer coefficients of degree N-1 f , L σ , L r , L m , where p, q do not have to be prime numbers, but must satisfy gcd(p, q) = 1, and q is far greater than p.

[0048] L(d 1 , d 2 )={F∈R:d of F 1 coefficient is 1, d 2 coefficients are -1, and the remaining coefficients are 0}

[0049] L f =L(d f , d f-1 )

[0050] L σ =L(d σ , d σ-1 )

[0051] L r =L(d r , d r-1 )

[0052] L m =m∈R: The coefficient of m is in t...
