To determine the degree of security in two-wave encryption under practical conditions, we present a novel numerical technique for simulating the recording and readout of two-wave encryption. The calculation results of the retrieval characteristics show that the diffraction efficiency in an incorrect decryption is 10 times as low as that in correct decryption key and that the output data with an incorrect key is a white noise image. We estimate the necessary key correlation to decrypt an encrypted data is 0.2 when the length of an encryption key is 2313. This means that the decoding probability of the encryption key in two-wave encryption is less than $10^{-6}$ even if such a short key is used.
