A CRYPTOGRAPHIC FLOW-BASED SECURITY PROTOCOL FOR AEROSPACE COMMUNICATION

Resumen de: US20260095320A1

A satellite receives, from a ground station, multiple first commands out-or-order for replicating a conflict-free replicated dataset at the satellite. An authority to access the conflict-free replicated dataset is retrievable from a block of a blockchain.

System and Method for Verifying Compliance Metadata Associated with Blockchain-Based Entity Credentials.

Resumen de: AU2026201944A1

Abstract With this invention, a computer-implemented system and method are provided for managing and verifying compliance metadata associated with a blockchain-based compliance credential.

METHODS AND DEVICES FOR AUTOMATED DIGITAL CERTIFICATE VERIFICATION

Resumen de: EP4718768A2

A public key may be recorded on the blockchain by a certificate authority in such a manner that any third party may quickly and easily verify that the public key is certified by the certificate authority and that the certification has not been revoked. The certificate authority may be able to revoke the certification nearly instantaneously, and/or may be able to simultaneously certify a new key for the same entity while revoking the old key. The verification may be incorporated into a new transaction so that there is no gap between reliance on the certificate and the verification of its validity. In some cases, each transaction in which the certificate is used may also serve as linked certificate transaction that renews the certificate to enable a subsequent use.
