Collis has introduced an NFC Two-factor Asymmetrical Chip Authentication application called NFC-2ACA—or NFC two-factor asymmetrical chip authentication. The application has been developed by integrating 2ACA into the contactless payment card protocols and the Near Field Communication protocol.
Collis has developed the 2ACA application that enables third-party authentication based on standard EMV implementations. Collis has enhanced this contact chip based 2ACA authentication scheme by integrating 2ACA into the contactless payment card protocols and the NFC protocol.
This authentication scheme will enable banks and mobile network operators to increase the customer value of their standard contactless products such as EMV cards, NFC-capable mobile phones and SIM cards. Functionality is offered for single sign-on on corporate networks, secure building access, strong authentication, e-mail signing and remote network access using the security of EMV like asymmetrical cryptography.
Authentication can be useful in several situations and can be made possible through different technologies. NFC-2ACA is an authentication method based on EMV that uses the NFC technology.
