In this paper, a three-key triple data encryption algorithm (TDEA) of a digital cryptosystem based on phase-shifting interferometry is proposed. The encryption for plaintext and the decryption for the ciphertext of a complex digital hologram are performed by three independent keys called a wavelength key k1(λ), a reference distance key k₂(d<SUB>r</SUB>) and a holographic encryption key k₃(x, y), which are represented in the reference beam path of phase-shifting interferometry. The results of numerical simulations show that the minimum wavelength spacing between the neighboring independent wavelength keys is about δλ = 0.007 nm, and the minimum distance between the neighboring reference distance keys is about δd<SUB>r</SUB> = 50 nm. For the proposed three-key TDEA, choosing the deviation of the key k₁(λ) as δλ = 0.4 nm and the deviation of the key k₂(d<SUB>r</SUB>) as δd<SUB>r</SUB> = 500 nm allows the number of independent keys k₁(λ) and k₂(d<SUB>r</SUB>) to be calculated as N(k₁) = 80 for a range of 1,530–1,562 nm and N(d<SUB>r</SUB>) = 20,000 for a range of 35–45 mm, respectively. The proposed method provides the feasibility of independent keys with many degrees of freedom, and then these flexible independent keys can provide the cryptosystem with very high security.
