A one-time password generated by a SIM card for authentication purposes.
Description
SIM-generated OTP (One-Time Password) refers to a security feature that utilizes the Subscriber Identity Module (SIM) embedded in mobile devices to generate a temporary password for authenticating users, including Non-Human Identities (NHIs). NHIs can include automated systems, devices, or applications that require secure authentication to access services. The OTP is typically generated through an algorithm that combines unique device identifiers with time-sensitive elements to ensure that each password is unique and valid for only a short period. This method enhances security by preventing unauthorized access, as the OTP must be received on the device associated with the SIM card. In the context of NHIs, SIM-generated OTPs can be used for machine-to-machine (M2M) communications, where devices need to authenticate with servers securely. This mechanism is vital in sectors like IoT, where devices must prove their identity to interact with networks or cloud services.
Examples
- A smart meter that sends data to a utility company using a SIM-generated OTP for secure communication.
- An IoT-enabled vending machine that authenticates its transactions through a SIM-generated OTP.
Additional Information
- SIM-generated OTPs are often used in mobile banking and transaction verification.
- This method is considered more secure than static passwords, as they change with each authentication attempt.
