Mechanism.
In the present embodiment, the public key to use symmetric encipherment algorithm, public key and private key to application asymmetric encryption calculate
Method, wherein symmetric encipherment algorithm is selected from following algorithm: DES (Data Encryption Standard), 3DES (Triple
DES),AES(Advanced Encryption Standard).And rivest, shamir, adelman selects ECC (Elliptic
Curves Cryptography): elliptic curve cipher coding theory.Elliptic curve is because use binary cubic equation y^2=x^3+ax
+ b indicates, similar oval perimeters accounting equation and gain the name.Open Secret key arithmetic will be based on a difficult math question, and elliptic curve is calculated
Method is namely based on discrete logarithm problem.Elliptic curve on finite field Fp equally has addition, but cannot give geometric meaning
Explanation.Wherein the addition on elliptic curve is such as given a definition:
Infinite point O ∞ is null element, there is O ∞+O ∞=O ∞, O ∞+P=P
The negative member of P (x, y) is-P (x ,-y), there is P+ (- P)=O ∞
P (x1, y1), Q (x2, y2) and R (x3, y3) have following relationship:
x3≡k2-x1-x2(mod p)
y3≡k(x1-x3)-y1(mod p)
Wherein if P=Q k=(3x2+a) if/2y1 P ≠ Q, k=(y2-y1)/(x2-x1)
Consider following equation:
K=kG, wherein K, G are the point on Ep (a, b), and k is the integer less than n (rank that n is point G), it is not difficult to find that given
K and G calculates K and is easy to according to Adding law；But given K and G, asks k with regard to relative difficulty.Here it is elliptic curve cryptography calculations
The problem that method uses, we are commonly referred to as discrete logarithm problem.Point G is called basic point (base point) by we, and (k < n, n are k
The rank of basic point G) it is known as private cipher key (privte key), K is known as public-key cryptography (public key).
Wherein ECC is compared with RSA, and have in many aspects to absolute advantage, be mainly reflected in: attack tolerant is strong；Meter
Calculation amount is small, and processing speed is fast；Memory space occupies small；Bandwidth requirement is low.These features of ECC make it that will replace RSA, become
General public key encryption algorithm, so block chain also uses ECC.
And the signature algorithm SECP256K1 used in block chain in the present embodiment is a kind of standard of elliptic curve
Change expression way, wherein 256 indicate that the elliptic curve is 256, K represents Koblitz curve, corresponding elliptic curve
Standard changes expression in addition, SECP192K1, SECP192R1, SECP224K1, SECP224R1, SECP256R1, SECP384R1,
SECP521R1 etc..
SECP256K1 curve is defined by following functions, which can produce an elliptic curve:
Y^2=(x^3+7) } over (Fp)
The reason of so choosing, also for consistent with the output valve of hash algorithm SHA256, and solve it is discrete right
Several difficulty.The process that coded communication is carried out using elliptic curve will now be described:
User A selectes an elliptic curve Ep (a, b), and takes on elliptic curve a bit, as basic point G.
User A selects a private cipher key k, and generates public-key cryptography K=kG.
Ep (a, b) and point K, G are transmitted to user B by user A.
After user B is connected to information, plaintext to be transmitted is encoded to the upper point M of Ep (a, b), and (there are many coding method, here
It is not covered), and generate a random integers r (r < n).
User B calculates point C1=M+rK；C2=rG.
C1, C2 are transmitted to user A by user B.
After user A is connected to information, C1-kC2 is calculated, is as a result exactly point M.Because of C1-kC2=M+rK-k (rG)=M+rK-r
(kG)=M
Being decoded again to point M can be obtained by plain text, this is signature algorithm SECP256K1 is used in block chain basic
Principle.
In the present embodiment also by the way that one or more of hashing algorithms are applied to institute's received new transaction block next life
At second hashed value.Signature mechanism is electronically sent by authentication information by the sending device of processing server, further includes:
The transaction block of signature and the domain public key of signature are received from signature mechanism by the receiving device of processing server, wherein the affairs signed
Block includes the second hashed value of new transaction block and signature.It is signed using domain corresponding with signature field public key private key；Also,
The transaction block of signature is verified using member public key and signature field public key by the authentication module of processing server.Verify the thing of signature
Business block includes: that the domain public key of signature is applied to the transaction block of signature to generate the second hashed value of new transaction block and signature；
Member public key is applied to the second hashed value of signature to generate the second hashed value；And generated second hashed value is verified
For corresponding to the second hashed value generated.
