Hologram Multi-factor Authentication (MFA)

Hologram Does:

1. Establish Trust

Initial key storage at time of secure SIM manufacturing establishes trust without loading and coordinating certificates

2. Embed Physical Hardware Security in IoT Devices

Hologram secure IoT SIMs provide a hardware-based 'something you must have' security element for multi-factor authentication (MFA)

3. Build developer tools to enable unique one-time-passwords for machines (OTP-M)

Enable MFA in only a few lines of code with Hologram developer tools

4. Develop nonce and challenge-response scheme

All Hologram secure IoT SIMs have an encoded nonce and challenge response scheme to generate OTP-Ms

5. Validate Device Authentication/Identity

Hologram validates OTP-Ms for message authentication and device identification

6. Automatic continuous key rotation

Hologram secure IoT SIMs rotate new keys to prevent forward and backward secrecy vulnerabilities

7. Reestablish Trust Remotely

When an incident occurs, Hologram remotely updates new keys for authentication

You Do:

1. Build your Product
2. Send a message with Hologram MFA Contact Sales
