Introduction Secure Shell (SSH) is a cryptographic network protocol that allows for secure communication between two devices over an insecure network. SSH is often used to securely log in to remote computers or servers, and to securely transfer files between computers.
Using SSH with IoT Core IoT Core provides a managed SSH service that you can use to securely connect to your devices. This service is easy to use and provides a number of benefits, including:
- Authentication and authorization: SSH uses public-key cryptography to authenticate and authorize users. This means that you can be sure that the person you are connecting to is who they say they are.
- Encryption: SSH encrypts all data that is transmitted between your device and the SSH server. This ensures that your data is protected from eavesdropping.
- Tunneling: SSH can be used to tunnel other types of traffic through an SSH connection. This can be useful for securely accessing services that are not normally accessible over SSH.

Secure Shell (SSH) is a cryptographic network protocol that allows for secure communication between two devices over an insecure network. SSH is often used to securely log in to remote computers or servers, and to securely transfer files between computers.
- Authentication
- Authorization
- Encryption
- Tunneling
- Public-key cryptography
- Remote access
- Secure file transfer
- Managed SSH service
These aspects of SSH make it an essential tool for securely managing and accessing IoT devices. SSH provides a secure channel for communication between devices, ensuring that data is protected from eavesdropping and tampering. SSH also allows for remote access to devices, making it possible to manage and troubleshoot devices from anywhere with an internet connection.
1. Authentication
Authentication is the process of verifying the identity of a user or device. In the context of IoT Core SSH, authentication is used to verify the identity of the user or device that is attempting to connect to an IoT Core device. This is important because it ensures that only authorized users or devices can access the device and its data.
- Public-key cryptography
Public-key cryptography is a type of cryptography that uses two keys, a public key and a private key. The public key is used to encrypt data, while the private key is used to decrypt data. IoT Core SSH uses public-key cryptography to authenticate users and devices. When a user or device attempts to connect to an IoT Core device, the device sends its public key to the IoT Core service. The IoT Core service then uses the public key to encrypt a challenge message and sends the challenge message back to the device. The device then uses its private key to decrypt the challenge message and send the decrypted message back to the IoT Core service. If the decrypted message matches the original challenge message, the IoT Core service authenticates the user or device.
- X.509 certificates
X.509 certificates are another type of credential that can be used to authenticate users and devices. X.509 certificates are issued by a certificate authority (CA). When a user or device attempts to connect to an IoT Core device, the device sends its X.509 certificate to the IoT Core service. The IoT Core service then uses the certificate to verify the identity of the user or device.
- IAM roles
IAM roles are used to control access to resources in Google Cloud Platform (GCP). When a user or device attempts to connect to an IoT Core device, the IoT Core service checks the user's or device's IAM roles to determine whether the user or device is authorized to access the device.

Authentication is an essential part of IoT Core SSH. By using strong authentication mechanisms, IoT Core SSH helps to ensure that only authorized users and devices can access IoT Core devices and their data.
2. Authorization
Authorization is the process of determining whether a user or device is allowed to access a specific resource. In the context of IoT Core SSH, authorization is used to determine whether a user or device is allowed to connect to an IoT Core device and perform specific operations on the device.
Authorization is an important part of IoT Core SSH because it helps to ensure that only authorized users and devices can access IoT Core devices and their data. This is important for protecting the security and privacy of IoT devices and their data.
There are a number of different ways to authorize users and devices in IoT Core SSH. One common way is to use IAM roles. IAM roles are collections of permissions that can be assigned to users and devices. When a user or device attempts to connect to an IoT Core device, the IoT Core service checks the user's or device's IAM roles to determine whether the user or device is authorized to access the device.
Another way to authorize users and devices in IoT Core SSH is to use access control lists (ACLs). ACLs are lists of users and devices that are allowed to access a specific resource. When a user or device attempts to connect to an IoT Core device, the IoT Core service checks the ACL for the device to determine whether the user or device is allowed to access the device.
Authorization is an essential part of IoT Core SSH. By using strong authorization mechanisms, IoT Core SSH helps to ensure that only authorized users and devices can access IoT Core devices and their data.
3. Encryption
Encryption is the process of converting data into a form that cannot be easily understood by unauthorized people. In the context of IoT Core SSH, encryption is used to protect the data that is transmitted between an IoT Core device and an SSH client. This is important because it ensures that the data is protected from eavesdropping and tampering.
IoT Core SSH uses strong encryption algorithms to protect data in transit. These algorithms make it very difficult for unauthorized people to decrypt the data, even if they have access to the encrypted data.
Encryption is an essential part of IoT Core SSH. By using strong encryption, IoT Core SSH helps to ensure that the data that is transmitted between IoT Core devices and SSH clients is protected from eavesdropping and tampering.
4. Tunneling
Tunneling is a technique that allows for the secure transmission of data over an insecure network. In the context of IoT Core SSH, tunneling is used to create a secure channel between an IoT Core device and an SSH client. This is important because it allows for the secure transmission of data between the device and the client, even if the network that the data is transmitted over is insecure.
To create a tunnel, an SSH client establishes an SSH connection to an SSH server. Once the SSH connection is established, the client can create a tunnel to the IoT Core device. The tunnel is a secure channel that is encrypted and authenticated. This ensures that the data that is transmitted through the tunnel is protected from eavesdropping and tampering.
Tunneling is a valuable tool for securely managing and accessing IoT devices. It allows for the secure transmission of data between devices, even if the network that the data is transmitted over is insecure. Tunneling is also useful for securely accessing devices that are located behind firewalls or other network security devices.
5. Public-key cryptography
Public-key cryptography is a type of cryptography that uses two keys, a public key and a private key. The public key is used to encrypt data, while the private key is used to decrypt data. IoT Core SSH uses public-key cryptography to authenticate users and devices. When a user or device attempts to connect to an IoT Core device, the device sends its public key to the IoT Core service. The IoT Core service then uses the public key to encrypt a challenge message and sends the challenge message back to the device. The device then uses its private key to decrypt the challenge message and send the decrypted message back to the IoT Core service. If the decrypted message matches the original challenge message, the IoT Core service authenticates the user or device.
Public-key cryptography is an important part of IoT Core SSH because it provides a secure way to authenticate users and devices. By using public-key cryptography, IoT Core SSH helps to ensure that only authorized users and devices can access IoT Core devices and their data.
Here are some real-life examples of how public-key cryptography is used to secure IoT devices:
- Smart homes: Smart homes use IoT devices to control a variety of devices, such as lights, thermostats, and security systems. Public-key cryptography is used to secure the communication between these devices and the smart home hub.
