Abstract:
TETRA (TErrestrial Trunked RAdio) is one of the mobile telecommunication standards which has improved in several aspects (voice, data, video, coverage, etc.), especially the security section during the last two decades. Although communication could be quite secure in TETRA when the encryption is used, however, attackers create new ways to bypass the encryption without the knowledge of the legitimate user. Security is performed in different levels and forms to create reliable operation and to protect information through the transmission path from interception and tampering. Since most of the TETRA users require the highest possible level of security, in this thesis we introduce a new configuration to keep the communication safe against interception and disruption by attacker or natural hazard; we have also proposed a new circuit to create more reliable operation and protect the information from tampering, disclosure and eavesdropping by warning the user in cases where the transmitted message is not encrypted because of manipulation by an attacker or accidental damage
