In addition, the application adopts a buffer character stream mode for reading and writing the user data, adopts a buffer character stream mode for increasing the data processing speed by reducing Input/Output (I/O) operation, and can read and write 8k bytes of data for one I/O operation, while a conventional physical stream can only read and write 1 byte of data, namely, process the data with the same scale, and can obviously reduce the times of the I/O operation by using the buffer character stream mode, thereby increasing the data processing speed.
In some embodiments, the key of the above-described block encryption algorithm may be generated in such a way that:

In step 102, a prime number data table is generated according to a preset prime number range, a preset number of prime numbers in the prime number data table are extracted to construct an initial prime number data space, the prime number data table after prime number extraction is traversed to obtain residual prime numbers in the prime number data table, the residual prime numbers and prime numbers in the initial prime number data space are replaced according to a preset replacement probability, and the prime number data space is determined.
In some embodiments, for example, a prime number data table may be generated by using Java parallel streaming according to a preset prime number range, where the prime number data table may include all small prime numbers within a range, which is not limited herein.
In some embodiments, for example, if a prime number data table contains n prime numbers, a prime number data space capable of storing m prime numbers is constructed, the first m prime numbers in the prime number data table are extracted and stored in the prime number data space to obtain an initial prime number data space, then prime numbers starting from the m+1th prime number in the prime number data table are traversed, whether the prime numbers are replaced in the initial prime number data space is determined according to m/n replacement probability, and when all prime numbers in the prime number data table are traversed, m randomly selected elements are in the prime number data space obtained.
In step 103, a first odd number of corresponding digits is randomly generated according to the preset digits, a first number to be verified is determined according to the prime number data table, the prime number data space and the first odd number, and after the first number to be verified passes prime number verification, the first number to be verified is used as a first random large prime number.
In some embodiments, based on the Java running environment, the preset number of bits, for example 1024 bits, is determined by inputting the number of bits of the large prime number to be generated, and the system randomly generates a large integer corresponding to 1024 bits according to the input preset number of bits 1024 by a random () method.
In some embodiments, the first odd number and the second odd number are odd integers obtained by eliminating the integer with the predetermined number of bits generated randomly by the even integer according to the characteristic that the last bit of the binary number of the odd integer is necessarily 1, because the even number is certainly divisible by 2, the even number is necessarily not prime number, and according to the characteristic that the last bit of the binary number of the odd integer is necessarily 1 and the even number is necessarily 0, the integer and the 1 are subjected to OR operation to judge whether the integer is odd or even, so that the even integer can be eliminated, and the obtained integer is ensured to be odd as the first odd number.
In some embodiments, the determining the first to-be-verified number according to the prime number data table, the prime number data space and the first odd number may be implemented by:
firstly traversing the prime number data table, carrying out remainder operation on each prime number in the first odd number and the prime number data table, randomly extracting one prime number from the prime number data space and adding the prime number to the prime number data space to be used as a number to be eliminated when the remainder is 0, then eliminating an even number, carrying out prime number verification on the first odd number as a first number to be verified when the remainder is 1, determining the first number to be verified as a first random large prime number when the verification is passed, randomly extracting one prime number from the prime number data space again and adding the prime number to be used as the number to be eliminated when the verification is not passed, and further executing the elimination of the even number again, which is not repeated here.
In step 104, a second odd number of the corresponding digit is randomly generated according to the preset digit, a second number to be verified is determined according to the prime number data table, the prime number data space and the second odd number, and after the second number to be verified passes prime number verification, the second number to be verified is used as a second random large prime number.
In some embodiments, based on the number of bits of a large prime number to be generated, for example 1024 bits, in a Java running environment, the system randomly generates a large integer of the corresponding number of bits by using a random () method according to the number of input bits.
In some embodiments, since the even number must be divisible by 2, the even number must not be a prime number, and the integer is ored with 1 to eliminate the even integer, thereby ensuring that the resulting integer must be an odd number, which is the second odd number, based on the characteristic that the last bit of the binary number of the odd integer must be 1 and the even number must be 0.
Traversing the prime number data table, carrying out remainder operation on each prime number in the second odd number and the prime number data table, randomly extracting one prime number from the prime number data space and adding the prime number to the prime number data space when the remainder is 0, returning the prime number to the even number elimination step as a prime number to be eliminated, carrying out prime number verification on the second odd number as a second prime number to be verified when the remainder is 1, regarding the second prime number to be verified as a large prime number when the verification passes, taking the second prime number to be verified as a second random large prime number, randomly extracting one prime number from the prime number data space and adding the prime number to be eliminated, and returning the prime number to the even number elimination step as a prime number to be eliminated when the verification fails.
In some embodiments, when the second random large prime number is generated, the obtained large prime number is compared with the first random large prime number, when the generated prime numbers are different, the large prime number is used as the second random large prime number, when the generated prime numbers are identical, one prime number is randomly extracted from the prime number data space, added with the prime number and then used as the number to be eliminated, and the even number elimination step is carried out.
It should be noted that, in the present application, prime verification is performed on the first to-be-verified number and the second to-be-verified number, which may be performed in the following manner, that is:
firstly, for the number n to be judged (the number n is a first number to be verified or a second number to be verified in the embodiment), judging whether the number is 2 or not, if yes, directly returning to true, otherwise, continuing judging whether the number is less than 2 or even, and if yes, returning to false;

Since x is necessarily smaller than n during the cycle, the quadratic detection theorem can be used if during the operationI.e. +.>If n is prime, then +.>Or->Otherwise, n is not necessarily prime number, and the false is directly returned;
after the whole cycle is finished, if x is not equal to 1, the number is certainly not prime, and false is directly returned.
In step 105, a storage public key is determined according to the first random prime number and the second random prime number, a key of the block encryption algorithm is encrypted according to the storage public key to obtain a key ciphertext, and the key ciphertext and the user data ciphertext are uploaded to a storage system of the hong and Monte-Sum system for storage.
In some embodiments, determining the stored public key from the first random large prime number and the second random large prime number may be performed by:
firstly, determining a storage modulus according to a first random large prime number and a second random large prime number;
secondly, determining the least common multiple according to the first random large prime number and the second random large prime number;
and finally, obtaining a storage public key according to the least common multiple, the storage modulus and a random integer.
