Abstract
A distributed key generation system and a key generation method are provided. The distributed key generation system includes a plurality of electronic devices and a server device. Each electronic device sends a data fragment. The server device synthesizes the key according to the data fragments. In this way, the key is not generated in advance, which can reduce the risk of key leakage.
Claims15
A distributed key generation system, comprising:
- a plurality of electronic devices, each electronic device sending a data fragment;
- and
- a server device, configured to receive the data fragments sent by the electronic devices, and perform multiple times of quadrature or summation operations according to the data fragments, so as to generate a sequence after each operation;
- wherein the server device is further configured to cascade each sequence and perform hash algorithm to form a seed, and generate a key according to the seed.
