What is IBC?

Identity-based cryptograph (IBC) is an identity-based cryptographic technology developed based on the Traditional PKI (Public Key Infrastructure, it mainly reduces the complexity of deploying and using specific security applications and avoids the exchange of a large number of digital certificates generated by security applications.

Both IBC and RSA are asymmetric encryption algorithms. The differences between IBC and RSA are as follows:

1. Public Key source

The RSA public key is a string of numbers generated by random calculation. It must pass the certificate before it can be associated with the user's identity,
Certificate Management requires a complex infrastructure (Public Key Infrastructure: PKI)

The IBC public key can be any character data, which can be easily directly associated with the user's identity or role without passing through certificate exchange and building related expensive infrastructure.

3 IBC Technology Innovation

• NoThe digital certificates in the PKI system do not require the CA center of the Certificate Authority, and do not require the issuance and query of certificates,

  Easy to use and easy to deploy, especially for security systems of massive users

• NoCertificates verification and other computing processes in PKI have a low computing cost and are suitable for mobile terminals.
• NoOnline connection to the CA Server of PKI to query and verify the certificate status, with a low communication cost
  Rich policy control mechanisms that combine identity authentication and access control into one
