Benefits of technology

The patent text describes a new type of cryptographic certificate called a BIX certificate. This certificate is similar to X.509 certificates, which are used to verify the binding between user identities and their public cryptographic keys. The new program enables applications and transactions to verbalize sensitive personal and business information while maintaining privacy and anonymity for the users and data. The main technical effect is to enhance security services for users and transactions while providing privacy and anonymity for the users and data.

Problems solved by technology

If the infrastructure is unpermissioned this means that it does not have sponsoring entities that approve users who want to join the infrastructure.

[0064]The Structure and Attributes of BIX Certificates

[0065]BIX certificates are cryptographically encapsulated objects that provide binding between identities of their owners and their public keys, provide cryptographic mechanism (digital signature) to verify that binding and correctness of certificate attribute values and in that way enable distribution of identities and cryptographic keys to transaction partners and verification of the binding and correctness of attribute values by those partners. These features with BIX certificates are achieved with the full anonymity of all BIX system members.

[0066]The structure and attributes of BIX certificates and protocols for their creation, distribution, and verification support the three main purposes of these certificates: (1) reliably distributing and using the correct and legal identities and correct cryptographic keys of BIX system members, (2) verification of user identities and cryptographic keys, and (3) binding of identities to ...

Abstract

Systems and methods for managing public key certificates and supporting the users thereof. The certificates are cryptographically encapsulated objects that bind the identities of their owners to public keys and provide digital signature mechanisms for other users to verify the binding and correctness of other attributes of the certificate. Certificates include double links that reflect their validation and position in a public certificates ledger, thereby preventing insertion or removal of certificates in the ledger. Certificate protocols of the system include requesting issuance of certificates, issuing and returning certificates to their requesting users, storing certificates in the certificates ledger, requesting and distributing certificates to transaction partners, verification of certificates by transaction partners, and revoking certificates by their owners. These protocols are performed as direct peer-to-peer transactions between the members of the system.
