Description
Technical field
The invention belongs to Internet of Things technical field of information processing, more particularly to it is a kind of based on the management of credit worthiness dynamic and domestic
Cryptographic algorithm privacy information encrypted transmission method.
Background technique
Currently, the prior art commonly used in the trade, which is such that Internet of Things refers to, to invest object for various information sensing devices
On part, information sensing device is combined with internet, forms the huge of interconnection between object, computer and people and information sharing
Big network then realizes the intelligence of article.With the development of technology of Internet of things, all trades and professions all make full use of information in society
Technology, medical industry also include that wherein, Internet of Things has pushed the Informatization Development of health and medical service, are continuously improving medical mistake
Journey improves quality of medical care, ensures patient safety, realizes tele-medicine, health care is provided for special population, reinforces medical instrument
Management and prophylactic agent etc. play a significant role.The network architecture of intelligent medical based on Internet of Things, majority design does not have
In view of the risk of patients' privacy leakage, the patient information that hardware device is collected into carries out plaintext transmission in a network.It is shared
Huge privacy leakage risk will be present in medical information.For entire medical industry, the leakage of medical data will be brought
Huge economic cost.This programme solves excessively shared patients' privacy in intelligent medical, patients' privacy information plaintext transmission and trouble
Person's private data is tampered.This programme can be effectively protected patients' privacy and not stolen by undesirable as commercial use, prevent
Only patients' privacy information is tampered inconvenient to patient's medical treatment bring.National Password Management office has issued SM2 in December, 2010
Ellipse curve public key cipher algorithm.The algorithm mainly includes three parts: Digital Signature Algorithm, Key Exchange Protocol, public key encryption
Algorithm.Digital Signature Algorithm includes digital signature generating algorithm and verification algorithm, can satisfy the authentication in cipher application
With the requirement of data integrity, authenticity.If message to be signed is M, in order to obtain the digital signature (r, s) of message M, as
The user of signer should perform the steps of (1) and set(ZAMark, part elliptical are distinguished about user A
The Hash Value of curve system parameter and user's A public key)；(2) it calculates(HvIt is v bit for eap-message digest length
Cryptographic Hash function)；(3) random number k ∈ [1, n-1] is generated with randomizer；(4) elliptic curve point (x is calculated1, y1)
=[k] G；(5) r=(e+x is calculated1) modn, C is returned if r=0 or r+k=n；(6) s=((1+dA) is calculated-1·(k-r·
dA)) modn, C (d is returned if s=0AFor the private key of user A)；(7) signature of message M is (r, s).SM4 algorithm full name is SM4
Block cipher is No. 23 password professional standard number announced in announcing of publication national Password Management office in March, 2012
For (standard No. is GM/T 0002-2012), the publication of in August, 2016 is known as national standard (standard No. GB/T32907-2016).
SM4 algorithm is a grouping symmetric key algorithm, and plaintext, key, ciphertext are all 16 bytes, and encryption and decryption keys are identical.Add
Close algorithm and key schedule all use 32 wheel nonlinear iteration structures.Decrypting process is similar to the structure of ciphering process, only
It is the opposite using sequence of round key.1) enciphering and deciphering algorithm defines antitone mapping R are as follows: R (A0, A1, A2, A3)=(A3, A2, A1,
A0),I=0,1,2,3 set in plain text input asCiphertext exportsRound key isI=0,1,2 ..., 31.Then the encryption of this algorithm becomes
It is changed to:
(Y0, Y1, Y2, Y3)=R (X32, X33, X34, X35)=(X35, X34, X33, X32)；The decryption transformation of this algorithm and encryption
Mapped structure is identical, and different is only round key using sequence.Round key uses sequence when encryption are as follows: (rk0, rk1...,
rk31)；Round key uses sequence when decryption are as follows: (rk31, rk30..., rk0)。
In conclusion problem of the existing technology is: currently, intelligent medical just rapidly develops, using secure context
Protection there is also larger problem, since the object of intelligent medical connection is mainly patient and doctor, for both sides' privacy
Seem particularly significant, safety problem becomes the most important thing in Internet of Things.
(1) there are huge disclosure risks for privacy information when seeing a doctor on carrying out line by present patient, to patient's
Normal life causes huge negative effect.
(2) patient medical privacy information has huge commercial value, it is thus possible to be stolen as illegal business use
Patient personal interests are caused to encroach on way.
Solve the difficulty and meaning of above-mentioned technical problem:
The system that the present invention designs a message, file Hybrid Encryption transmission and credit worthiness dynamic management, to privacy of user
It encrypts, the privacy of user is enabled to obtain appropriate protection.Meanwhile the present invention uses the state of China's independent research
Produce cryptographic algorithm.
