Side-X™ Secure Token

Achieve the highest levels of endpoint security for your customers, staff and connected devices with Tyfone’s Side-X™ secure element product family.

SideCard™ Secure Token in CR80 Form Factor

The only effective way to mitigate the risks associated with cybersecurity and static-password based authentication is to enable high-grade endpoint hardware security in the hands of authorized users. SideCard™ is Tyfone’s industry-leading endpoint security hardware device, which allows an organization to implement decentralized and distributed user authentication in a convenient, familiar form factor. SideCard provides strong authentication and increased safeguards, significantly reducing cybersecurity risks and operational costs.

SideCard is based on Tyfone’s patented hardware endpoint security technology. It leverages an industry-standard smartcard and contains Bluetooth (BLE) interface, NFC contactless or EMV contact interfaces, providing SideCard the flexibility to be used at EMV terminals, point of sale devices, and also accessed via Bluetooth for securing all digital transactions across mobile & non-mobile devices.

SideCard interoperates with Tyfone’s u4ia™ digital security platform for identity & transactions, providing layered step-up security that supports all NIST levels of assurance, including the highest levels in the industry, while not compromising convenience & user experience.

Secure Element

The smart card Secure Element (SE) in the SideCard™ is an industry standard, providing highest levels of built-in tamper resistance, secure storage and hardware encryption. The SE allows storing of credentials, cryptographic keys, and X.509 certificates, making it non-extractable by hackers.

Public Key Cryptography

The applet supports cryptographic algorithms to enable strong authentication and transactional security. The applet makes use of the hardware based cryptography functions and supports NSA’s suite B cryptographic functions.

Strong Authentication

SideCard™ combines “What the user has” and “What the user knows” to provide two-factor authentication. The security credentials stored inside of the SideCard™ can be used for either Hardware One Time Password (OTP) or challenge–response based implementation. The OTPs are generated as per standards-based RFC recommendations. The challenge-response is based on standard cryptographic functions.

Transaction Security

The keys and certificates stored in the SideCard™ can be used to establish mutually authenticated TLS connection between an access device and any application server, such as payment gateways, etc. The transactions between the device and the application server can thereafter be protected using standard cryptographic functions, as AES256.

Easy Deployment, Easy to Use

In addition to EMV contact & NFC contact-less use cases, Tyfone SideCard™ communicates to wireless host devices using Bluetooth Low Energy (BLE), which is supported widely by all mobile platforms. Tyfone’s standards-based APIs enable SideCard™ to integrate with any application — on any platform (mobile, desktop or terminal device). This enhances the authentication and security of the application, with minimum user interaction, making it easy to use and deploy.

The simple, easy to use form factor provides a Convenient and positive user experience, while enabling the highest levels of security available in the industry.
