A hybrid encryption algorithm based on AES and RSA is proposed to enhance the security of data transmission in Bluetooth communication. E0 algorithm is currently used in transmission of data via Bluetooth between two or more devices. E0 is a 128-bit symmetric stream cipher used in the Bluetooth protocol. Several attacks and attempts at cryptanalysis of E0 and the Bluetooth protocol have shown that it may be broken in 264 operations. In the proposed hybrid encryption algorithm, instead of the E0 encryption, AES algorithm, known for of its higher efficiency in block encryption is used for data transmission and RSA algorithm is used for the encryption of the AES key due to its key management advantages.
