1 Introduction

IOT is delivering a compelling technology innovation. Connecting variety of devices with each other and allowing them to participate in data sharing results in new products and services. IOT devices store this collected data in the cloud where various AI applications are used to perform analytics. AWS helps in storing a vast amount of data collected by the IOT devices continuously in real-time. But the optimum potential of these smart devices using AI-enabled applications to perform analysis on this data and gain considerable insights such that data provide significant information, but this can solely be attained by using effective security mechanisms. AWS uses a manifold layers to provide deterrent security methods like access control to data and encrypting the data. Amazon web services provide efficient security services to keep the collected data secure.

2 Authentication

Authentication is one of the crucial security parts of the IOT devices. AWS IoT services provide tools for creating secure key authentication. Various credentials like private keys and digital certificates are involved in authenticating edge devices with the AWS platform. Users should not be allowed to set up credentials of services to authenticate their devices with AWS. Also, the credentials should not be revealed to manufacturer of the devices and any entity part of the development process like personnel and delivery pipeline. These devices would become vulnerable if the credentials are disclosed [1].

It would lead to data leak and modification without authorization. This data could include personal information that is collected from offices, homes. Improper authentication would lead to counterfeiting and impersonation [1].

The major issue involved is how the device will securely validate the authenticity of the AWS endpoint it connects to.

The certificate chain also needs to be created securely and the supplying of private key to the edge device. The device’s private key is main or crucial part of the security paradigm. As it will be used to conduct verification during connecting to AWS IoT. In spite of being highly secure, AWS still cannot maintain integrity unless the device is not protected appropriately. Also it is important to ensure that all the keys, i.e. public, private, and processes are kept separate from device operations [1].

AWS uses microchip technology’s safe component ATECC608a to provide device-level security and effective authentication mechanism. The component provides various hardware-level security methods and techniques like storing all the keys and certificates in a safe environment and removing vulnerabilities. This component is used to generate a private key that acts as a root for certificate used for securing networked devices. Basically private key is a unique identifier. While authenticating with the AWS IoT platform, the edge devices use it for communicating data to the platform [4, 6].

The microchip technology’s component that is embedded in the device is built in a way that encapsulates the private key such that it becomes impossible to manipulate the private key [4].

The certificates, private key, and the public key infrastructure (PKI) are available through various means. It depends on the user’s choice and business requirement as to which options should be considerably better as per the requirement. Either the complete infrastructure of the component-producing firm can be incorporated or AWS native security infrastructure for authentication can be used.

Also, third party and custom CA’s can be used as per the context in which it is to be used. And even the authentication model can be fully customized to cope with specific security risk [4].

AWS IoT security model includes authentication mechanisms to authenticate devices with the AWS IoT platform and authorizing them to perform required actions.

Consider using edge device for booking cab online rather than using a cab-booking app on smartphone and providing various details in order to confirm a ride. An edge device like Amazon IoT button can be used to rapidly book rides on just a click of a button. These buttons are programmable and can be configured in the cloud. They can be used for various purposes like alerting or calling someone, ordering services online, order a cab, open gates remotely and check-in & check-out in hotels, etc [5].

When the button is clicked the information about who clicked it and at what location is necessary to book a ride, as it is done in smartphone applications using mobile numbers, usernames to uniquely identify a customer. Similarly, AWS IoT button needs a unique identifier to confirm authenticity. Devices using MQTT network protocol will use X.509 certificate [5].

AWS IoT uses public key cryptography or asymmetric cryptography for creating unique identity and signing documents. The digital signature to a message is used to verify whether the original message has been received and no modifications or tampering took place. It will also be used to demonstrate possession of the private key. The X.509 certificate exhibits possession of a public key. Each edge device will have a unique identity, which will be done using separate X.509 certificate for each device. Three major options available for generating a certificate devices are, first a certificate generated by the AWS IoT can be used, which includes a public and private key and certificate signed by the AWS IoT Certificate Authority. Second option available for generating certificate is to use one’s own Certificate signing authority, in this scenario, the AWS will not be aware about the private key. Last option is to use certificate of Certificate authority, which you find reliable and trustworthy. Root certificate, which is used by the AWS IOT, is also needed to set up a secure and authentic connection with the AWS IoT platform. All the keys and certificates generated earlier need to be stored on the cab booking button or edge device to be used during authentication procedure.

5 AWS IoT Security Model

AWS IoT security model includes authentication mechanisms to authenticate devices with the AWS IoT platform and authorizing them to perform required actions.

Consider using edge device for booking cab online rather than using a cab-booking app on smartphone and providing various details in order to confirm a ride. An edge device like Amazon IoT button can be used to rapidly book rides on just a click of a button. These buttons are programmable and can be configured in the cloud.

Similarly AWS IoT button needs a unique identifier to confirm authenticity. Devices using MQTT network protocol will use X.509 certificate [5].

AWS IoT uses public key cryptography or asymmetric cryptography for creating unique identity and signing documents. The digital signature to a message is used to verify whether the original message has been received and no modifications or tampering took place. It will also be used to demonstrate possession of the private key. The X.509 certificate exhibits possession of a public key. Each edge device will have a unique identity, which will be done using separate X.509 certificate for each device. There are three major options available for generating a certificate devices. First one is a certificate generated by the AWS IoT which includes a public and private key and certificate signed by the AWS IoT Certificate Authority. Second option available for generating certificate is to use one’s own Certificate signing authority, in this scenario, the AWS will not be aware about the private key. Last option is to use certificate of Certificate authority, which you find reliable and trustworthy. Root certificate, which is used by the AWS IOT, is also needed to set up a secure and authentic connection with the AWS IoT platform. All the keys and certificates generated earlier need to be stored on the cab booking button or edge device to be used during authentication procedure.

6 Authentication to AWS IoT

When all the keys and certificates are installed on the edge device, i.e. AWS IoT button then it is ready to create a secure connection to AWS IoT platform and communicate with it. The Transport Layer Security protocol (TLS) that is used is to create secure connections while using banking services and other payment gateways are used here to set up a connection between AWS IoT platform and the AWS IoT button and the digital certificate stored at the edge device is used to prove its unique identity and demonstrate its authenticity [5].

The AWS IoT button starts by sending a HELLO message to the component of AWS IoT responsible for verifying the identity of edge device [3] (Fig. 1).

After all the successful authentication procedures, the AWS IoT platform is now certain of the edge device it is communicating with, cab booking device of a particular passenger in this case. The unique id of the edge device tells the AWS IoT as to which passenger is trying to set a connection. The shared secret to be used is dependent on the cipher suites algorithm that the AWS IoT and the edge device uses, i.e. key exchange algorithm decided during Transport Layer Security (TLS) handshake. The AWS IoT button uses the server’s public key to encrypt the message, which was obtained from the server’s certificate. The server uses its private key to decrypt the message received from the AWS IoT button. After this procedure, both the parties are now able to set up a shared secret and further communication will be secured using this agreed upon shared secret [8].

7 Permission to Book

After all the authentication has been performed, i.e. the AWS IoT platform has been verified and AWS IoT button has authenticated it’s unique identity using X.509 certificate to the server and secure messages are being transferred, shared secret has been set up. The button is ready for booking a cab. The MQTT message, which the button or edge device sends, looks like “iotdashbutton/G01XXXXXXXXX”. The second half is the serial number corresponding to the edge device. The security of the AWS IoT button should be in a manner such that minimal authorization is provided to the passengers. Otherwise, there can be a scenario where an atrocious customer can modify or alter the program and impersonate to manipulate the system and book a cab inappropriately. A policy needs to be associated with the device certificate, which will authorize that specific identity. The serial number was contained in the certificate, which was transmitted while authenticating the device [3].
