The need for protecting the secret information from the un-authorized users has been led to
applying a lot of encryption approaches. However, there is high importance in ciphering the …

This paper presents an enhanced version of an existing encryption algorithm by combining
wavelets and chaos theory concepts. The novelty consists in replacing the simple …

In information transmission such as speech information, higher security and confidentiality
are especially required. Therefore, data encryption is pre-requisite for secure …

Text encryption in video is a vital tool in many industries where protecting sensitive
