METHODS AND DEVICES FOR PUBLIC KEY MANAGEMENT USING A BLOCKCHAIN

Resumen de: US2025158817A1

A blockchain network may be used to improve upon public-key infrastructure by providing for fast and secure registration, revocation and update of digital certificates.

She then calculates the root value of the Merkle tree that represents the data comprising the varied data sample. She sends her data to a storage provider, Bob, while retaining her sample(s) and the resulting Merkle root value(s). Alice does not tell Bob which sample(s) she has chosen, or the operations she has used in the variations, or any inputs to the operations. Alice can delete her original copy of the data. At a later date, Alice can verify that Bob still has her complete data and in its original state by requiring him to perform the same operation on the same data sample, calculate the root value of the resulting Merkle tree and send it to her. If Bob's root value matches Alice's root value, then Bob must have an original and complete copy of Alice's data otherwise he would not be able to calculate the correct Merkle root value. Embodiments can be arranged to fully automate the process, including implementing on a blockchain.

BLOCKCHAIN-IMPLEMENTED METHOD AND SYSTEM

Resumen de: EP4542932A2

The computer-implemented invention provides a method and corresponding system for controlling access to and/or use of an internet-enabled resource. The invention uses a distributed electronic ledger such as, for example, the Bitcoin blockchain. The resource may be an IoT device or system. Access to the resource is permitted or enabled upon provision of a cryptographic key e.g. a private key which corresponds to a public key which has been stored in memory. In one embodiment, the public key is stored in a DHT. Access to the resource is prevented or disabled by removing the public key from memory, and using a redeem script of a blockchain Transaction to spend a tokenised output of a further blockchain Transaction. The process of communicating the requisite cryptographic keys and transferring funds is performed via the blockchain. The keys are communicated as tokens in the metadata of transactions scripts. In use, when access is requested by the user, an encrypted message is sent to the resource. The message has been encrypted using the user's private key. If the resource can use the previously communicated public key to decrypt the message, access can be granted. The invention is particularly suited for use in situations where temporary access or use of the resource is to be granted eg rental scenarios.
