Description
Technical Field
The application relates to the technical field of license file activation, in particular to a license activating method.
Background
A software license generally refers to a legal document that governs the use and distribution of a computer software product or program. Typically, a software license grants a user the right to use a copy of a copyrighted software product. The software license may also interpret terms of use and may clarify restrictions on the rights granted to use the software.
The license management may be encrypted and decrypted by an RSA encryption algorithm, which is an asymmetric encryption algorithm. RSA is widely used in public key cryptography and electronic commerce. The RSA algorithm is based on a very simple number theory fact that it is very easy to multiply two large prime numbers, but it is extremely difficult to factorize the product, so the product can be disclosed as an encryption key. The RSA public key cryptosystem uses different encryption keys and decryption keys, and is a cryptosystem in which it is computationally infeasible to derive a decryption key from a known encryption key.
The difficulty of factoring the very large integers determines the reliability of the RSA algorithm. In other words, the more difficult it is to factorize a large integer, the more reliable the RSA algorithm is. If one finds a fast factorization algorithm, the reliability of the information encrypted with RSA must be extremely reduced.
However, the conventional industrial RSA algorithm is not universal in different platforms and heterogeneous systems, and particularly, encryption and decryption methods between a PC system and embedded equipment with low operation capability are not uniform.

RSA encryption and decryption algorithm description:
the encryption and decryption algorithms for Fx, fx may be implemented using the disclosed asymmetric RSA or symmetric DES algorithms. To consider the operation conditions of different embedded devices, the application adopts an asymmetric RSA algorithm to realize the encryption link. The SDK needs to use the public key and the private key fixed by RSA to realize a series of work of decrypting and verifying the license and activating.
The following is an introduction to RSA:
the RSA algorithm is an asymmetric cryptographic algorithm, meaning that the algorithm requires a pair of keys, one of which is used for encryption and the other for decryption.
The algorithm of RSA involves three parameters, n, e1, e2.
Where n is the product of two large prime numbers p, q, the number of bits occupied in binary representation of n is the so-called key length.
e1 and e2 are a pair of related values, e1 can be arbitrarily taken, but requires that e1 and (p-1) × (q-1) be mutually exclusive; and then e2 is selected, and (e2×e1) ≡1 (mod (p-1) × (q-1)) is required.
(n, e 1), (n, e 2) is the key pair. Where (n, e 1) is a public key and (n, e 2) is a private key.
The algorithm of RSA encryption and decryption is identical, and A is plaintext, B is ciphertext, then: A≡Be 2 (mod n); b≡a≡e1 (mod n); (in the public Key cryptosystem, public Key encryption and private Key decryption are generally used)
e1 and e2 may be used interchangeably, namely:
A≡B^e1(mod n)；B≡A^e2(mod n)。
it is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being within the scope of the application, obvious variations or modifications may be made thereto.
