Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and in conjunction with example.
1, heretofore described public-key cryptosystem and digital certificate are all made of improved RSA Algorithm, specific to improve
Scheme is as follows:
Since n is a very big integer, in key generation phase, encryption key is solved using n and is decrypted close
The efficiency of the calculating speed of key is low-down.In addition, if be in plain text also a big integer during cryptographic calculation,
The cryptographic calculation of so algorithm is exactly that the power of one big integer multiplies, and same decryption operation is also that the power of one big integer multiplies, this
Sample, which will lead to power multiplication, becomes unusual complexity, and calculating speed is very slow.
Traditional RSA Algorithm working principle is as follows:
First, the generation of key:
(1) the Big prime p and q of two secrecy are chosen altogether；
(2) n=p*q is calculated,WhereinIt is the Euler's function value of n；
(3) an integer e is chosen, is metAnd
(4) d is calculated, is metThat is d is e in mouldUnder multiplicative inverse, because e withMutually
Element, according to modular arithmetic, its multiplicative inverse is certainly existed；
It (5) is open key with { e, n }, { d, n } is secret keys；
Second, encryption:
Plaintext Bit String is grouped first when encryption, so that the corresponding decimal system of each grouping is less than n, i.e. block length is small
In log2n.Then to each clear packets m, make cryptographic calculation: c ≡ me mod n。
Third, decryption:
Decryption operation to ciphertext block are as follows: c ≡ cd mod n。
Improved RSA Algorithm proposed by the present invention, by the understanding to traditional RSA Algorithm, algorithmic procedure can substantially divide
For the following two stage:
(1) key generation phase: the security work of raw information is completed, it is necessary to key is first generated, if can be promoted
The formation speed of key, so that it may reduce the execution time of algorithm, and the multiple decomposition of n is also to complete in key generation phase
Improvement.
(2) encrypting stage and decryption phase: being the stage most important work to encryption of plaintext and to the decryption of ciphertext.
It is multiplied by the way that plaintext M is split into multiple small prime numbers, finally carries out total product calculation again, encryption and decryption are promoted with this
Speed shortens and calculates the time.
The calculating process of RSA Algorithm is made of key generation phase and encrypting and decrypting stage, it is necessary to firstly generate key
It just can be carried out encryption and decryption, therefore 2 stages of algorithm are the progressive relationships of level.Algorithm total execution time is by two stages
Operation time be added, i.e., key generate operation time add encryption and decryption operation time, so effectively promoted calculate
Method total execution time, it is necessary to promote the operation time in the two stages.
Improved RSA Algorithm is in detailed process, and by taking ciphering process as an example, the algorithm description is as follows:
(1) m Big prime p is randomly selected1,p2,...,pm, and maintain secrecy；
(2) n=p is calculated1×p2×...×pm, φ (n)=(p1-1)×(p2-1)×...×(pm- 1), n is disclosed；
(3) positive integer an e, 1 < e < φ (n) and gcd (e, φ (n))=1 are randomly chosen, e is disclosed；
(4) according to ed ≡ 1mod (φ (n)), d is found out, and is maintained secrecy to d；
(5) open { n, e } is used as encryption key, and { n, d } is used as decruption key, secrecy p1,p2,...,pm, φ (n)；
(6) plaintext M is split into multiple small integers to be multiplied, i.e. M=M1×M2×...×Mr, and M1,M2,...,MrAll
It is prime number；
(7) each prime number is ranked up from small to large, i.e. M1≤M2≤...≤Mr；
(8) it calculates separately: C1=M1 eModn, C2=M2 eModn ..., Cr=Mr eModn, r=1,2 ... r }；
(9) total product calculation is finally carried out, the calculating of RSA cryptographic algorithms: C=C is finally completed1×C2×...×Cr；
The symbol description of above-described RSA Algorithm is as shown in table 1 below:
1 symbol description of table
| Sequence | Symbol | Symbol description |
| 1 | p | Prime number |
| 2 | n | The product of multiple prime numbers |
| 3 | φ(n) | The Euler's function of n |
| 4 | e | The integer randomly selected |
| 5 | gcd(e,φ(n)) | The greatest common factor (G.C.F.) of e and φ (n) |
| 6 | {n,e} | Encryption key |
| 7 | {n,d} | Decruption key |
| 8 | M | In plain text |
| 9 | C | Ciphertext |
Algorithm performance analysis: big Integer n is decomposed into multiple prime numbers and is multiplied, specific number can be arbitrary, certainly
The number of the prime number of decomposition is more, and numerical value is with regard to smaller, and such computer is when carrying out operation to these prime numbers
Improve calculating speed.In addition, the multiple prime numbers decomposited in algorithm, increase the decomposition difficulty of modulus n, improve the peace of algorithm
Quan Xing.
Be experimentally confirmed: as n=2048bit, the decryption time of 4 decomposition algorithms of modulus n is traditional RSA Algorithm
2.69 times of decryption time are 1.90 times of 3 decomposition algorithms of modulus n, and specific data are as shown in table 2 below:
The table 2:RSA encryption and decryption time compares
| Experiment numbers | Traditional RSA | 3 decomposition are carried out to n | 4 decomposition are carried out to n |
| 1 | 0.1317 | 0.0899 | 0.0483 |
| 2 | 0.1296 | 0.0915 | 0.0475 |
| 3 | 0.1301 | 0.0934 | 0.0493 |
| Encryption and decryption time average (ms) | 0.1304 | 0.0916 | 0.0483 |
According to the data of upper table, it is recognised that repeatedly being decomposed in key generation phase to n, RSA calculation can be shortened
The calculating time of method, keep its more efficient.
By the way that traditional RSA Algorithm is optimized and improved, the encryption/decryption speed of RSA Algorithm can be effectively promoted, so that
The improved RSA Algorithm has better efficiency in online online electronic transaction of the present invention, authentication.
