Abstract
Embodiments of the present disclosure provide systems and methods for secure Short Message Service (SMS) communications. According to an embodiment, a method of providing secure Short Message Service (SMS) communications comprises requesting that SMS data to be sent from a client device to a remote location be encrypted. The method also comprises encrypting the SMS data by processing the SMS data with a Message Authentication Code (MAC) and a timestamp and/or counter along with second factor authentication information. The method further comprises sending the encrypted SMS data to the remote location by a secure SMS application via a regular SMS channel of the client device.
Claims29
A method of providing secure Short Message Service (SMS) communications comprising:
- requesting, by a secure SMS application loaded inside a client device, that SMS data to be sent from the client device to a remote location be encrypted internally by a Crypto component in the client device, wherein the secure SMS application is in communication with the Crypto component;
- encrypting, internally by the Crypto component in the client device, the SMS data by processing the SMS data with a Message Authentication Code (MAC) and a timestamp and/or counter along with second factor authentication information;
- sending the encrypted SMS data to the remote location by the secure SMS application via a regular SMS channel of the client device;
- receiving encrypted SMS data from the remote location via the regular SMS channel of the client device;
- and
- decrypting and reading the received encrypted data using the secure SMS application of the client device, wherein the decrypting and reading further comprises:
- receiving an HMAC timestamp and/or counter with the received encrypted SMS data;
- comparing the received HMAC timestamp and/or counter with a pre-determined appropriate timestamp and/or counter to determine veracity;
- once the received HMAC timestamp and/or counter is verified, processing a pre-registered unique identifier associated with the remote location that is known by the client device so that a position of such identifier is proven.
6 more elements
A client device comprising:
- one or more processors;
- and
- one or more memories adapted to store a plurality of machine-readable instructions which when executed by the one or more processors are adapted to cause the client device to:
- request, by a secure SMS application loaded inside the client device, that SMS data to be sent from the client device be encrypted internally by a Crypto component in the client device, wherein the secure SMS application is in communication with the Crypto component;
- encrypt, internally by the Crypto component in the client device, the SMS data by processing the SMS data with a Message Authentication Code (MAC) and a timestamp and/or counter along with second factor authentication information;
- send the encrypted SMS data to a remote location by the secure SMS application via a regular SMS channel of the client device;
- receive an HMAC timestamp and/or counter along with received encrypted SMS data from the remote location via the regular SMS channel of the client device;
- compare the received HMAC timestamp and/or counter with a pre-determined appropriate timestamp and/or counter to determine veracity;
- once the received HMAC timestamp and/or counter is verified, process a pre-registered unique identifier associated with the remote location that is known by the client device so that a position of such identifier is proven;
- and
- decrypt and read the received encrypted SMS data using the secure SMS application of the client device.
8 more elements
A secure SMS system comprising:
- a client device in communication with a remote location via a network;
- one or more processors;
- and
- one or more memories adapted to store a plurality of machine-readable instructions which when executed by the one or more processors are adapted to cause the secure SMS system to:
- encrypt, internally by a Crypto component in the client device, SMS data to be sent from the client device by generating a Hash Message Authentication Code (HMAC) using an encryption algorithm and applying the HMAC to a combination of a timestamp and/or counter with second factor authentication information internally in the Crypto component of the client device;
- send encrypted SMS data via a secure SMS application using a regular SMS channel of the client device to the remote location, wherein the secure SMS application is in communication with the Crypto component;
- receive an HMAC timestamp and/or counter with received encrypted SMS data from the remote location via the regular SMS channel of the client device;
- compare the received HMAC timestamp and/or counter with a pre-determined appropriate timestamp and/or counter to determine veracity;
- once the received HMAC timestamp and/or counter is verified, process a pre-registered unique identifier associated with the remote location that is known by the client device so that a position of such identifier is proven;
- and
- decrypt and read the received encrypted SMS data using the secure SMS application of the client device.
