Abstract
A method of transmitting a message via a blockchain network is provided. A method may include encrypting, via a first identity-based encryption (IBE) function, a message to generate a ciphertext. The method may further include transmitting the ciphertext to each node of a plurality of nodes in a blockchain network. Further, the method may include decrypting, via a second IBE function, the ciphertext at each node of the plurality of nodes in the blockchain network after at least one condition is met.
Claims20
A method of transmitting a message via a blockchain network, the method comprising:
- encrypting, via a first identity-based encryption (IBE) function, a message to generate a ciphertext;
- transmitting the ciphertext to each node of a plurality of nodes in a blockchain network;
- and
- decrypting, via a second IBE function, the ciphertext at each node of the plurality of nodes in the blockchain network after at least one condition is met.
One or more non-transitory computer-readable media that include instructions that, when executed by one or more processing systems, are configured to cause the processing system to perform operations, the operations comprising:
- encrypting, via a first identity-based encryption (IBE) function, a message to generate a ciphertext;
- transmitting the ciphertext to each node of a plurality of nodes in a blockchain network;
- and
- decrypting, via a second IBE function, the ciphertext at each node of the plurality of nodes in the blockchain network after at least one condition is met.
