A method and an apparatus for providing multiple-layers of encryption/decryption of contents and the transferring of protected content between devices based on each device's multiple IDs. Furthermore, it related to a two-way secure communication between two or more devices. The encryption/decryption is based on a common content ID that is used for providing multiple layers of encryption that can be used by hardware and software. Each byte of the digital stream is XORed with each byte of the content ID thus providing the encryption strength. The same process is applied to the encrypted content (ciphertext) thus reproducing the plaintext. As well, means for encrypting/decrypting digital content using its plain byte values as part of the content private key's registers.
