Business, damage population unit's interests a possibility that.
Virtual machine image embedding algorithm process is broadly divided into two steps.
The first step encrypts watermark cleartext information, and watermark must directly show virtual machine copyright ownership in plain text, for example,
" copyright of this virtual machine and built-in whole softwares, middleware returns middle seven 〇 mono- of ship heavy industry to own ".Utilize high-level programming language
Realize RSA tool-class, pseudo-code of the algorithm is as follows:
A pair of of public key and private key are generated using RSA tool-class, watermark cleartext information is encrypted using public key, obtains water
Print ciphertext.
Refer to that insertion watermark information should have confidentiality and lower false detection rate.Virtual machine image digital watermarking uses RSA
Rivest, shamir, adelman encrypts watermark cleartext information.Method is as follows:
1) a different prime pair (p, q) is randomly selected；
2) public modulus m=p × q is calculated, the two-stage system length of m is key length；
3) Euler's numbers are calculatedDue to the multiplicative function characteristic of Euler's function, thereforeIt is right
For prime number p, q, meetTherefore
4) an integer e is randomly choosed, is metAnd e withIt is relatively prime；
5) calculate e forMould antielement d, meetSolve equation:
So far, (m, e) is public key, and (m, d) is private key.The ascii value of water intaking print plaintext, is denoted as k, ciphering process
Are as follows: ke=c (mod m), solving c is encrypted watermark ciphertext.
Since private key is stored in the watermark producer namely virtual machine all rights reserved side, as long as private key is not revealed, reason
The possibility not being cracked by upper watermark information；It, can benefit using the information of public key encryption for a pair of of public key and private key
It is decrypted with private key, restores watermark information original text, due to the reliability of RSA Algorithm, the digital water of virtual machine image
The possibility of error detection is not present in print.
Watermark ciphertext is embedded into virtual machine file system by second step.According to the requirement of concealment and robustness, watermark
Ciphertext is embedded in several configuration files and dynamic link library file in integrated service document cluster in a manner of annotating, with aobvious control collection
For service, there are a large amount of public aobvious control plug-in units under the path Widgets/Debug, exist in the form of dynamic link library, it is interior
Hold the machine code that can not be understood for people, such as select libTimeCode.so therein, using text editor in machine code
Between insertion one section annotation, notes content be previous step generate watermark ciphertext；It is also similar for the operation of configuration file,
In Config.xml file under the root directory, it can be inserted into watermark ciphertext in the form of useless label, not influence xml text
The normal parsing of part.
Next the virtual machine image comprising software object running environment can be issued, if subsequent generation dispute over copyright,
It can be solved in such a way that watermark authenticates.Any one place's watermark ciphertext is found in virtual machine file system first, it is then sharp
Watermark ciphertext is decrypted in private key corresponding to the public key used when with encrypted watermark plaintext, can restore watermark in plain text,
Virtual machine copyright ownership, encrypting and decrypting the process signal such as Fig. 3 of digital watermarking can be clearly determined according to the content of watermark plaintext.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
