Cryptographic algorithms used by Mobile Subscribers to protect the privacy of their cellular voice and data communication. Mobile network is the shared media. When media are shared, privacy and authentication are lost unless some method is established to regain it. Ciphering provides the mean to regain control over privacy and authentication. A5/x are the encryption algorithms used in order to ensure privacy of conversations on mobile phones. The strong version A5/1 is used in most countries. A5/2 is weaker version used in countries on which export restrictions apply. A5/3 encryption algorithm used for 3G and GEA3 encryption algorithm used for GPRS. f8 is confidentiality algorithms developed by 3GPP, bringing out the commonality between A5/3 and GEA3 algorithms. The following paper is based on simulation of A5/1, A5/3 and f8 algorithms.
