Abstract
Due to extremely high demand of mobile phones among people, over the years there has been a great demand for the support of various applications and security services. Cryptographic algorithms used by Mobile Subscribers to protect the privacy of their cellular voice and data communication. 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. A5/3 encryption algorithm used for 3G and GEA3 encryption algorithm used for GPRS. f8 is confidentiality algorithms developed by 3GPP used in UMTS System. The following paper is based on simulation of A5/3 and f8 algorithms.
