CRYPTOGRAPHIC METHODS AND SYSTEMS FOR MANAGING DIGITAL CERTIFICATES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18652087 titled 'CRYPTOGRAPHIC METHODS AND SYSTEMS FOR MANAGING DIGITAL CERTIFICATES

Simplified Explanation: Digital certificates are created for devices by a Certificate Authority (CA) through a Registration Authority (RA) to ensure the anonymity of the association between certificates and devices. Each certificate is linked to a public signature key and a public encryption key derived from a single key by the CA. This innovative approach reduces bandwidth and computational costs.

• The CA and RA cannot associate certificates with devices
• Certificates are associated with a public signature key and a public encryption key
• Both keys are derived from a single key by the CA
• Reduced bandwidth and computational costs are achieved
• High security is maintained even without the CA signing the encrypted certificate

Potential Applications: 1. Secure communication between devices 2. Authentication of devices in a network 3. Ensuring data privacy and integrity in IoT devices

Problems Solved: 1. Anonymity of device-certificate association 2. Reduced bandwidth and computational costs 3. Enhanced security in digital communication

Benefits: 1. Improved security measures 2. Cost-effective solution 3. Efficient data encryption and decryption processes

Commercial Applications: The technology can be utilized in IoT devices, network security systems, and digital communication platforms to enhance data security and privacy.

Questions about Digital Certificates: 1. How do digital certificates ensure the anonymity of the association between certificates and devices? 2. What are the potential applications of digital certificates in IoT devices?

Frequently Updated Research: Ongoing research focuses on enhancing the encryption algorithms used in digital certificates to further improve security measures.

Original Abstract Submitted

Digital certificates are generated for devices by a Certificate Authority (CA), which communicates with devices via another entity—registration authority (RA)—so that the CA and RA cannot associate certificates with devices. Each certificate is associated with a public signature key, and with a public encryption key used by CA to encrypt the certificate to hide it from the RA. Both keys are derived by CA from a single key. For example, the signature key can be derived from the public encryption key rather than generated independently. However, high security is obtained even when the CA does not sign the encrypted certificate. Reduced bandwidth and computational costs are obtained as a result. Other embodiments are also provided.
