Than in the present embodiment, with Das scheme (Das M L, Saxena A, Gulati V P.A dynamic ID-based
remote user authentication scheme[J].IEEE Transactions on Consumer
Electronics, 2004,50 (2): 629-631) and Wang scheme (Wang Y Y, Liu J Y, Xiao F X, et al.A
more efficient and secure dynamic ID-based remote user authentication scheme
[J] .Computer Communications, 2009,32 (4): 583-585) it compares, safety comparison is as shown in table 2.
Wherein √ expression can be resisted, × indicate to resist.
2 safety analysis of table
| Scheme | Das scheme | Wang scheme | This paper scheme |
| Ddos attack | × | × | √ |
| It internals attack | √ | × | √ |
| Spoof attack | × | × | √ |
| Guessing attack | × | √ | √ |
| Man-in-the-middle attack | √ | √ | √ |
2, distributed denial of service (DDoS) attack is resisted
The distributed frame of block chain is based on the point-to-point network architecture, if a node failure, Bu Huiying
It rings other nodes to work normally, therefore single point failure problem is not present.Relative to the serving system architecture of centralization, it is to refusal
Service attack is effectively more.Once the user connecting with malfunctioning node then cannot be introduced into system because node breaks down.
3, it internals attack
As user UiWhen being registered, logged in and being authenticated, user UiEntry password is inputted, server S carries out user information
Hash operation obtains x, it is assumed that malicious user C intercepts x, since Hash function has one-way and anti-collision, malicious user
C is difficult to release user information, effectively prevent internaling attack.
4, spoof attack
In block chain, since the activity between arbitrary node is by the supervision of the whole network, and database is using distribution
Formula storage can not be pretended to carry out fraudulent activities for malicious user C.
5, guessing attack
In the present invention program, as user UiWhen being registered, it is assumed that malicious user C can intercept IDi,PWiEtc. information,
But random number n is that system is distributed automatically when carrying out registration operation, so C is unable to get n, to be unable to get private key KsWith with
Family address UaddrInformation；As user UiWhen being logged in and being authenticated, since malicious user can not obtain station address information Uaddr
(exclusive evidence of user log-in authentication), so can not be logged in and be authenticated, so that login failure, effectively resists password guess
Attack.
6, man-in-the-middle attack
For the present invention program in user's registration, login and certification, user is by user information and password PWiCarry out Hash operation
Cryptographic Hash x is obtained, server is sent to by safe lane, guarantees that authentication information will not be tampered.When server and node are logical
When letter, ID is transmitted by safe lanei,Uaddr, y and relevant information, malicious user C can not be distorted.
7, operand is analyzed
This section will analyze the operand of the program, and with the identity authentication scheme of other same types such as Wang scheme
It is compared with Lin scheme, operand comparison is as shown in table 3.
The analysis of 3 operand of table
The present invention program and Wang scheme (Wang Y Y, Liu J Y, Xiao F X, et al.A more efficient
and secure dynamic ID-based remote user authentication scheme[J].Computer
Communications, 2009,32 (4): 583-585) compare, lack 6 Hash operations, more 2 digital signature and verifyings
With 1 subelliptic curved line arithmetic.But the identity authentication scheme mentioned of Wang scheme can not effectively avoid internaling attack etc. it is common
Network attack.And this paper scheme uses block chain technology, and 2 transaction are generated in user's registration, login and certification, and encloses 2
A signature, so this programme mostly solves Wang scheme (Lin Y K.A P2P identity using the operand of 2 signatures
authentication techn-ology that prevents man-in-the-middle attacks[J]
.Electronic Technology&Software Engineering, 2017, (13): 214-215. (in Chinese))
Network attack problem.This programme and Lin project plan comparison, have lacked 4 public key encryptions and decryption operation, more 2 digital signature and
Verifying, 1 Hash operation and 1 subelliptic curved line arithmetic.Since the calculating speed of hash algorithm is much higher than public key algorithm, so this
The computational efficiency of literary scheme is higher than Lin Scheme.It is analyzed by operand, this paper scheme is based on block chain technology, can
The reduction computing cost of effective and safe, and using common recognition algorithm, the fast speed so that network node is reached an agreement.
The above is only one embodiment of the present invention, it is noted that those skilled in the art,
Without departing from the concept of the premise of the invention, some similar deformation and improvement can be made, these also should be regarded as this
Within the protection scope of invention.
