This paper discusses the application of random network coding safety problems , when transfering files, and Puts forward an algorithm that targets eavesdropping adversaries By means of this algorithm,an eavesdropper is unable to get any meaningful information about the source,which we call weak security.We show that if we give up a small amount of over all capacity, then a random code achieves the weak security condition at a much higher probability. Besides, when there is a secret channel or apublic encryption scheme between the source and destination,an algorithm that not only achieves the max-flow but also the weak security condition is proposed.The probability of the coding scheme to be security is 1,when random codingscheme is used.
