The cipher text is safe when the cryptanalysis attack strength sustainable (bearable) by the ciphertext information matches with the cipher text value-cost, i.e., it is regarded as SAFE when the computational complexity required for an attack satisfies the threshold of the user's (determined by the information value) , which follows the computationable security principles (rules) of cryptography.
