How it works ?

1. Launch the VaultNFC application on the mobile phone
2. Approach the phone close to the tag (a VaultIC150), the tag is automatically detected by the application:
   • An authentication based on ECDSA is performed between the phone and the tag
   • The tag’s certificate is retrieved from the tag
3. If the previous authentication is successful, the VaultNFC application is contacting a trusted database using a SSL connection. Information (image…) and root certificate are retrieved from this database:
   • The root certificate is used to verify the validity of the tag’s certificate
   • An image linked to the product is displayed
4. At the end of the process, the VaultNFC application is showing a message to the user, to inform him whether the global authentication was successful or not.
5. All the information about the protected product can be viewed by clicking on the image being displayed.

VaultNFC solution

The solution provides:

• A fast and easy way to verify the authenticity of a product
• A cost effective solution, easy to use, to customize thus enabling a fast deployment
• A solution not altering the product itself unlike other existing solutions

The solution is based on:

• A Public Key Infrastructure, PKI
• The same level of hardware security used in banking cards and electronic passports
• A very efficient cryptography, the ECC, Elliptic Curves Cryptography
• FIPS certification, thus it reaches the highest security standard in the USA

The solution is composed of:

• A secure tag (secure microcontroller) which can have different antennas and different package form factors to address several markets.
• A NFC phone with the VaultNFC application. The phone acts as a reader and can be use directly by the customer
• Secure database where we can store information on the product and the tag

Main advantages:

• Takes advantage of the fast and large adoption of the NFC standard, thus it can leverage on the existing infrastructure
• Fully trusted solution using advanced cryptography standard like ECDSA enabling Inside Secure to provide a low cost solution compare to solution using RSA cryptography
