In this report, we present an encryption algorithm that can be used for hardware-implemented applications to secure data communications, this encryption algorithm is based on hiding a number of bits from plain text message into a random vector of bits, the locations of the hidden bits are determined by a key known to the sender and receiver, we call this algorithm hybrid hiding encryption algorithm (HHEA). The name demonstrates the two basic operations of this algorithm, these operations include inserting part of the plaintext bits into a cover to hide it from recognition, that is, there are no conventional operations on the ciphered text, just plain hiding in a random bit string, the name hybrid is used to show that the algorithm has built-in features that are inherited from data hiding techniques or steganography.
