In the actual operation process, all the networking terminals contained by the three parties form hardware equipment of the cloud service shared item transaction platform. Any one of the networked terminals can serve as any one of the two parties, or serve as both parties, or serve as three parties, for example, while the networked terminal serving as a service user provides services, different services may be acquired from the cloud service shared item transaction platform according to the identity of the service user; the networked terminal serving as the cloud service sharing project transaction platform may also have idle storage capacity and/or computing capacity, and may provide services to the user in the identity of the service provider after integrating the idle storage capacity and/or computing capacity.
Further, in this embodiment, the service integrator integrates idle computing power and/or storage power of all networked terminals together and submits the integrated power as service content to the platform manager, and the platform manager provides the service to the user in a free or paid manner according to the user demand.

All service users and service providers can share or trade computing capacity and storage capacity through the platform, so that resource allocation is optimized to a great extent, and resource utilization rate is improved.

Referring to FIG. 3, in particular, the method includes
S501, encrypting the provided item transaction service data:
s5011, encrypting the item transaction service data by using an AES algorithm to generate a first secret key.
In this step, data encryption is performed by using an AES algorithm. It should be noted that the AES algorithm is a symmetric encryption algorithm, and is generally divided into 4 steps: byte substitution, row displacement, column mixing, round key addition. Each step is reversible, so the decryption algorithm is the corresponding inverse operation. Where byte substitution is a non-linear byte-by-byte substitution operation that follows a substitution table. The line shift is a linear transformation, and each line of the state matrix is circularly shifted to the right by taking a byte as a unit, and the linear shift is a multiple of 4. In the column mixing stage, four elements in each column of the state matrix are used as coefficients to form a column polynomial, and the column polynomial is subjected to modular multiplication with a specific polynomial. And a round key adding stage, namely performing exclusive OR operation on the column of the round key matrix byte by byte and the column of the state matrix. The AES algorithm will encrypt and decrypt hundreds of times faster than the asymmetric encryption algorithm. The encryption and decryption process of the AES algorithm is shown in fig. 4.
As can be seen from the encryption and decryption process of the AES algorithm provided in fig. 4, the key to the security is to secure the key, and the security of the key is secured by the AES algorithm in the encryption chain. According to the key length, the AES algorithm can be divided into three versions, namely AES-128, AES-192 and AES-256. In order to speed up its decryption, in a preferred embodiment the electronic archive data is processed using the AES-128 version to generate the first key.
S5012, extracting a file number of the item transaction service data, and encrypting the file number by using a hash function to generate a number ciphertext; and iterating the numbered ciphertext by using an iteration function to generate a second secret key.
In this step, a second key is generated by a hash function encryption method.
In order to enhance the security of encrypted transmission, in this step, a hash function is used to encrypt the file number to generate a number ciphertext. Specifically, the MD5 is adopted to encrypt the file number to obtain a ciphertext, and then an iteration function is used to iterate the version number ciphertext to generate a second key.
In a specific embodiment, the number ciphertext is iterated by using a divergent non-invertible function Fun to generate a key of a 128-bit AES encryption algorithm as the second key. The serial number is encrypted by combining the Hash algorithm MD5 and the advanced AES encryption algorithm, and the indecomposability of the encryption algorithm is enhanced by diverging the non-reversible function, so that the safety of data transmission is greatly improved.
And S502, transmitting the encrypted data to the user, and carrying out a project transaction process after the user decrypts the encrypted data.
And finally, transmitting the encrypted data to the user, and only after the user can successfully decrypt the encrypted data, successfully entering a cloud service shared item transaction platform to normally perform an item transaction process, otherwise, failing to perform any item transaction.
In a specific embodiment, the providing item transaction services for users further includes:
sending a digital signature request to a user, receiving and verifying a digital signature returned by the user, and providing project transaction service for the user when the verification is passed; the generation process of the digital signature comprises the following steps:
encrypting a user private key by using an RSA algorithm to generate a random number;
and acquiring a legal certificate capable of proving the identity of the user, calculating the random number and the hash value of the legal certificate of the client by using an SHA algorithm, and encrypting the hash value by using an AES algorithm to generate a digital signature.
It should be noted that the RSA algorithm is one of the most commonly used asymmetric encryption algorithms, belongs to the most typical and perfect public key block cipher system at present, can resist most of cryptographic attacks at present, and has better confidentiality. The algorithm first generates a pair of RSA secret keys by a receiving party, wherein a public key can be issued in a network, and a secret key is only owned by a user; the sender uses the public key to encrypt the file and then sends the file to the receiver, and the receiver can decrypt the file by using the private key to recover the plaintext. Specifically, the core of the reciprocity of RSA encryption and decryption is euler's theorem, and the algorithm first needs to generate a pair of public keysp k And a private keys k Then need to usep k Encrypting the inscription, uses k And decrypting the ciphertext.
The SHA algorithm is the most widely used hash encryption algorithm following the MD5 algorithm, which has encryption irreversibility and is generally used as a digital signature to verify the validity of a data signature.
In the embodiment, in order to further enhance the security in the data transmission process, the user private key is encrypted by using the RSA algorithm to generate any random number; then, a legal certificate which can prove the identity of the user, such as an electronic identity certificate, a double-issue approved electronic protocol and the like, is obtained, finally, the random number and the hash value of the client side legal certificate are calculated by using an SHA algorithm, and the hash value is encrypted by an AES algorithm to generate a digital signature. Thus, the data security in the item transaction is further ensured.
In summary, the embodiments of the first aspect of the present application can achieve at least the following beneficial effects:
1) The project transaction method is provided based on the cloud server, project transaction sharing can be achieved, and system performance is optimized.
2) By adopting the block chain technology, the management authority of the private key can be given to the server, and the user equipment does not need to store the private key; the server ensures the safety of the private key and can help the user equipment to sign; therefore, the user can experience the service of the block chain without sensing the private key, and the user experience is further improved.
