Abstract

A method of generating at least one encryption key () for encrypting data (), a method of 5 data transmission between at least two communication systems (), a method of encrypting data () and a method of decrypting encrypted data () are disclosed. Further disclosed are an encryption key generating device (), a system (), a data encryption system () and a data decryption system (). The method of generating at least one encryption key () for encrypting data (), specifically for data transmission over an insecure channel, comprises: i. blending at least two materials () according to at least one item of blending in-formation by using a blending device (), thereby generating at least one blend (); ii. detecting at least one material property () of the blend () by using at least one detector (); and iii. transforming the material property () into the encryption key () by using at least one data processing device () configured for applying at least one trans-formation algorithm to the material property ().
