Abstract

The invention discloses a block chain cryptographic adaptation method, a cryptographic adapter and a storage medium. The method comprises the following steps: a block chain cryptographic service module initialization request is responded to; the cryptographic adaptercomponent prepares an initialization service, starts a configuration file of the block chain password service module, and initializes the cryptographicadapter component through a cryptographic adapterplug-in according to the configuration content of the configuration file; and the initialized cryptographic adapter component adapts to various underlying cryptographic algorithms according to different configurations, and provides a defined password interface end for nodes in the block chain network to support various cryptographic algorithms to adapt to a block chain server in the encryption machine. On the basis of the cryptographic adaptation method, pluggable of the cryptographic library can be achieved, and the purpose of using different cryptographic libraries is achieved.

Description

technical field [0001] The invention belongs to the technical field of block chain encryption, and in particular relates to a block chain national secret adaptation method, a national secret adapter, a system and a device. Background technique [0002] At present, mainstream blockchain companies try to apply national secrets to the blockchain, mainly focusing on: (1) replacing SHA-256 with SM3 as the default cryptographic hash algorithm; (2) replacing the elliptic curve signature algorithm with SM2 as Asymmetric encryption algorithm; (3) Replace RSA and elliptic curve algorithm certificates with SM2 certificates. For upper-layer protocols such as SSL, less is involved, and blockchain-related hardware facilities, such as hardware wallets, are rarely designed using national secret standards. In addition, because there is no specific standard for the national secret algorithm, it is difficult to apply national secrets to various cryptographic algorithms in the blockchain, that...

Problems solved by technology

In addition, because there is no specific standard for the national secret algorithm, it is difficult to apply national secrets to various cryptographic algorithms in the blockchain, that is, it is impossible to get through a variety of encryption algorithms to adapt to the national secret algorithm

[0003] There are a variety of encryption machines or encryption algorithms on the market, and the specific implementation details of each encryption machine or encryption algorithm are slightly different. If you adapt to different encryption algorithm implementations each time, you need to make a lot of changes to the code, which is not conducive to research and development efficiency. and system stability
