Abstract
A first network device (300) arranged to determine a shared key with a second network device (350), the first network device comprising a private key processing unit (330) arranged to substitute a second identity number (η) into a sequence of mixing functions ({ϕ
k |k = 0... α}) obtaining a sequence of mixing coefficients ({ϕ
k (η)|k = 0... α}), compute the sum (A) of multiple products of a private key coefficient (G
ξ
,
k ) of the sequence of private key coefficients with a corresponding mixing coefficient (ϕ
k (η)) of the sequence of mixing coefficients, reduce the sum modulo the public global reduction integer (N), and derive the shared key from the reduced sum.
