Abstract: The cryptographical characteristics of the data transmited in wire-tap channel of type two are described by Generalized Hamming weights of linear codes.The expression of the second and the third orders of support set have been given, and then, by using the simulated annealingneural network, the generalized Hamming weights of Hamming codes have been calculated.The results are the same to their theory values.Finally, some suggestionshave been given to the realization of simulated annealing algorithm.

Key words: neural network, simulated annealing, Hamming codes, generalized Hamming weights
