摘要：In [1], a hybrid approach to secure messages using encryption and steganography has been introduced. The methodology of the latter hybrid is to encrypt the secret data using the Advanced Encryption Standard (AES), then hiding the encrypted bits in the spaces of a carrier text using the Word Shift Coding Protocol (WSCP). In WSCP, the hiding process is achieved by increasing or decreasing the font size of the spaces in the carrier text. This hybrid has some limitations. As an extension for [1], these limitations have been resolved. On the other hand, compared to bare encryption, the performance remains considerably sluggish. For instance, we need 8.87 milliseconds to hide 50 characters using this approach, were we only need 0.12 milliseconds to encrypt the same number of characters using the AES with Counter (CTR) mode of operation.
