Abstract

The invention relates to the technical field of cryptogram and information safety, and discloses an implementation method and system for an SM3 algorithm in a JAVA environment. The implementation method specifically comprises the following steps that an adaptation layer for achieving algorithm replacement is developed based on a PKCS#11 standard; in the JAVA environment, when an application program calls a secure hash algorithm (SHA()-256 algorithm) in JAVA cryptography extension (JCE) through a programming interface of an encryption framework JCA standard, the adaptation layer directly calls the SM3 algorithm to achieve an application programming interface (API), operations and processing are carried out on data on which a hash algorithm needing to be carried out in a sublayer based on the SM3 algorithm, and thus the operation that the SHA-256 algorithm is replaced by the SM3 algorithm is achieved. The invention further discloses an implementation system for the SM3 algorithm in the JAVA environment. The algorithm ID of the SHA-256 algorithm is used for achieving the SM3 algorithm in the encryption framework JCA, the problem that a new algorithm cannot be added in the implementation of ready-made JCE is solved, and meanwhile the huge amount of workload for achieving new JCE and complex procedures for applying JCE authorized signatures are avoided.

Description

technical field [0001] The invention relates to the technical field of cipher and information security, and discloses a method and a system for realizing the SM3 algorithm in the JAVA environment. Background technique [0002] SM3 is a code hash algorithm. It is a commercial algorithm compiled by the State Cryptography Administration. It is used for digital signature and verification in cryptographic applications, generation and verification of message authentication codes, and random number generation. It can meet the security requirements of various cryptographic applications. For a message m with a length of l (l< 264) bits, the SM3 hash algorithm undergoes padding and iterative compression to generate a hash value with a length of 256 bits. [0003] JAVA is an object-oriented programming language that can write cross-platform application software. It is the general term for the Java programming language and Java platform (ie JavaSE, JavaEE, JavaME) launched by Sun Mic...
