Abstract: Many financial institutions interact with their customers via short message services (SMS), which is today one of the fastest and most powerful means of communicating information around the world. This information can sometimes be an access code such as the unique password (OTP) for two-factor authentication (2FA) or banking information and personal identities. All this data is confidential, and it is a major disadvantage to send them since an SMS service does not provide data encryption during network transmission and on mobile. Recently, OTPs via SMS have suffered from strong attacks that intercept messages. In order to avoid attacks and offer effective content security to 2FA credentials sent via SMS, the authors propose an SMS encryption mechanism using a post quantic cryptosystem quasi-cyclic MDPC and an electronic signature of the OTPs. Finally, this article performs an implementation and a security analysis of the proposal.
