The cryptography approach plays a very major role in securing systems by providing authentication, integrity, and confidentiality for the data. In recent decades, the cryptographic systems have provided novel and efficient ways of encryption. Most of these cryptographic systems need unpredictable entities-Keys. Hence Random number generator is an essential component for cryptography. In cryptography, generating random numbers is an important task, not only for generating cryptographic keys, but also for implementing cryptographic algorithms and protocols. This paper presents chaotic analog circuits to generate random numbers that is used as keys in the conventional cipher to protect the image data.
