End-to-End Data Protection of SMS Messages
MetadataShow full item record
Short Message Service (SMS) has become a very commonly used service. It does not only work as a substitute for voice telephony, but is also used for automated services. Some of these service are related to security issues like SMS banking, or one time passwords, even though SMS messages can be spoofed or eavesdropped.We propose a design where we add security to SMS by making an easily configurable module that utilizes a fast cryptographic scheme called Elliptic Curve Signcryption. To prove our concept, we implement an SMS client for Android smart phones that utilizes our security module and serves end-to-end data protection of SMS messages with the same security level as Top Secret content.
