Example embodiments
For example, the method provided by this embodiment may be run in a federation chain, for example, in a Hyperridge Fabric framework. HyperLegendr Fabric originally a distributed federation chain framework launched by IBM and Digital Asset. For convenience of description, it will be referred to as Fabric hereinafter.
The financial distributed ledger needs to meet certain requirements, the cryptographic algorithm used by the financial distributed ledger should meet relevant specifications, and with technology replacement, new cryptographic algorithms are always generated continuously, so how to adapt the financial distributed ledger to different cryptographic algorithms is a technical problem concerned by this embodiment. The following further explains the embodiment of the present invention by taking the newly added cryptographic algorithm service of the distributed ledger system as an example. The national cryptographic algorithm is an abbreviation of national general cryptographic algorithm, is an autonomous and controllable domestic cryptographic algorithm formulated by the national cryptographic administration, and comprises SM1, SM2, SM3, SM4, SM7, SM9, ZUC (ZUC) and the like.
The embodiment is based on the extension development of Fabric, so that the Fabric supports three national universal cryptographic algorithms of SM2, SM3 and SM4 formulated by the national cryptographic administration, and provides modular and pluggable national cryptographic services.
The scheme provided by the embodiment can add national Cryptographic algorithm support based on the most widely used fabric 1.4 version at present, and finally realizes complete decoupling of the cryptology Service suite interface and the specific national Cryptographic algorithm library by three steps of realizing a BCCSP (Block chain cryptographical Service Provider) (GM Cryptographic Service Provider, GMCSP for short), a national Cryptographic switch (GM Options, GMOPTS for short) and adding a new national Cryptographic interface.
In an exemplary embodiment, a national password switch is used to determine whether to enable the services of the national password algorithm. The switching of the national cryptographic algorithm can be realized by transmitting the OPTS parameter when the certificate is generated, if the parameter is 'national cryptographic', all algorithms related to the cryptography of the fabric system use the national cryptographic algorithm, namely, the national cryptographic algorithm is unified in all processes related to the cryptography, such as the certificate, the signature/signature verification of transaction, the tls communication, the encryption/decryption of messages and the like; conversely, if the parameter is "international," then all of the above cryptographic processes will use the native international cryptographic algorithm in the fabric accordingly.
The scheme provided by the embodiment can support the national secret algorithm library which is implemented by the national secrets SM2/SM3/SM4 and the gosang of tls. The part is that a large number of unit tests are added on the basis of the existing national cryptographic algorithm library, and a random uid value is used for signature verification of sm2 instead of an original empty uid value, so that the safety of the sm2 algorithm is enhanced. The country cipher algorithm library is put into the fabric/vendor for other modules calling the country cipher algorithm.
In an exemplary embodiment, the present embodiment also provides cryptographic certificate support.
In an exemplary embodiment, the present embodiment implements the BCCSP interface GMCSP, add GMFactory, add GMOPTS.
Fig. 4 is a schematic diagram of a process of providing Cryptographic algorithm Service according to an embodiment of the present invention, and as shown in fig. 4, the Cryptographic correlation in the Fabric is implemented by BCCSP (block chain Cryptographic Service provider), which is a uniform interface of the Cryptographic Service.
The BCCSP interface roughly comprises four types, namely key life cycle management, hash hashing, signature verification and encryption and decryption.
In one exemplary embodiment, the present solution includes the following steps:
first, we add the structure of GMCSP in the first step, mainly including the following fields:
a Keystore field. Is an interface type and is used for storing a private key of a national password.
A KeyGenerators field. Is a map type, key is a reflect type, and value is a KeyGen interface, which is used to generate keys.
A KeyImporters field. Is a map type, key is a reflect type, and value is a KeyImport interface, which is used to import the private key from the keystore.
Encryptors and Decryptors fields. All are map type, key is all type, value is respectively encrypt interface and decrypt interface. The method is used for realizing the functions of national secret encryption and decryption.
The signs and veriders fields. All are map type, key is all reflection type, value is Signers interface and verifers interface respectively. The method is used for realizing the signature and signature verification functions of the national password.
Hashers field. Is a map type. Type is type, value is Hasher interface, and is used for realizing the hash function of the cryptographic key.
Next, Gmfactory was added.
The Gmfg is a structure body for realizing native BCCSPFactory interface in Fabric, and comprises two methods of Name () and Get (opt < FactoryOpts) < bccsp, error). This ultimately returns GMCSP through this factory mode when providing cryptographic services.
In an exemplary embodiment, the procedure is described by taking the example that the KeyGen function of the country cipher algorithm library is called to generate the public private key of the country cipher algorithm:
calling a Get method through a BCCSPFactory interface, and returning a Gmfactory structure example by specifying a provider name (GM) in a reference FactoryOpts;
after the Gmfator instance is acquired, the KeyGen of the instance is called, and a KeyGenerator interface of the national password is returned;
after taking the KeyGenerator interface, call the KeyGen method;
a specific KeyGen function implementation to the underlying domestic cryptographic algorithm library is invoked. For example, the KeyGen function of the sm2 algorithm, completes the generation of the public and private keys.
Finally, a parameter "gm" or "sw" is received at cryptogen to decide whether a national password certificate or an international certificate is generated, if the parameter is "gm", the national password certificate is generated, then the national password certificate is converted into GmFactoryOpts in the get factor method of BCCSPFentity, and the later operations related to cryptography are called to Gmfactor and further converted into the national password algorithm.
In an exemplary implementation manner, a national cipher switch is provided in the scheme in this embodiment, so that an international cryptography algorithm or a national cipher algorithm can be flexibly switched, and hard coding is avoided.
In an exemplary implementation mode, the embodiment provides flexible and plug-in support of the national cryptographic algorithm, is decoupled from the underlying national cryptographic algorithm library, and has good expansibility and maintainability.
