Аннотация. Mobile device users prefer to preserve the privacy of their SMS communication from mass government surveillance and other adversaries using mobile device SMS encryption solutions. The mobile devices in use however, are highly constrained in terms of memory, power and computing capability to utilize the current SMS encryption solutions. There is a room for improvement in term of the speed efficiency of the SMS encryption schemes proposed for use on mobile devices. This paper propose an end-to-end SMS encryption scheme ideal for use on mobile devices using a hybrid combination of cryptographic algorithms: Blowfish symmetric encryption algorithm, Elliptic Curve Diffie Hellman (ECDH) and Elliptic Curve Digital Signature Algorithm (ECDSA). The proposed scheme will be implemented using Java programming language to develop SMS encrypting Android application. The time taken for the proposed SMS cryptographic operations will be measured on five different Android mobile devices with varying processor speed and will be compared with a related work to evaluate the proposed scheme’s speed. The cryptographic operations to be measured are the time taken for encryption and decryption and key generation. Keywords: encryption, SMS, Blowfish, ECDH-ECDSA, cryptography, security, privacy.
