All personal credentials are both cryptographically and physically secure on the steel-armored chip, wear-tested for 10 years of durability to insure extreme up-time-paramount because of the critical role this hardware token plays in establishing a person's digital identity. Because the iButton is carried on a key chain, or other convenient accessory it is always close at hand.

If logically attacked, the firewall of the iButton prevents access to the private keys. If physically attacked, the iButton has a tamper response that erases the private key rather than reveal it in order to preserve confidentiality. These protective measures comply with United States Government specifications for secure e-commerce under the NIST FIPS 140-1 cryptographic module validation program (http://csrc.ncsl.gov/ cryptval/140-1/1401val.htm#list1). The third party testing of cryptographic modules establishes a basis for very sensitive transactions on the Internet. In addition to the strong 1024-bit keys for secure log-on, the Java-powered iButton has a true time clock inside its cryptographic boundary for time stamping the e-signatures that are now legal signatures under laws enacted by the U.S. congress and other governments.

The Java-powered iButton can be worn on the accessory of choice Dallas offers a ring, watch, wallet, badge holders, metal card, and key fob-accessories that are for close keeping at all times and that people are well-practiced at not losing.

1. Large NVRAM up to 134K memory, can store over 30 x.509 certificates, hundreds of user name/passwords, and the application programs of many different service providers.
2. FIPS 140-1 level 3 validated by NIST as a secure cryptographic module.
3. True time clock for time-stamping transactions and self-imposing expiration dates for e-Signature applications
4. Made of stainless steel, its durable enough for everyday wear - drop, step on, scuff, submerse in water...
5. Wear on your choice of lifestyle accessory,ring, watch, wallet, badge holders, metal card, and key fob-accessories.
6. PKI support includes PKCS # 11(Netscape®), CSP (Microsoft®), X509 certificates.
7. Multiple independent services can coexist in the iButton and can be revised after issuance.
8. JavaCard 2 compliant to speed up development of applications using widely available tools for the Java language.
9. Standard cryptographic classes include SHA-1 for secret key digital signatures, RSA public key,
10. The Java-powered iButton combined with the 2-in-1 Fob is effectively a Java smart card with a built in USB reader. No other cabling is necessary.
