Social platform daily dialogue encryption method and system, storage medium and computing device

Abstract

The invention relates to a daily dialogue encryption method and system for a social platform, a storage medium and computing equipment. The method comprises the following steps: pre-appointing a random sequence key which is known and consistent to both parties of a dialogue; inputting a plaintext needing to be expressed and a random sequence key of an agreed number into an encryption tool, wherein an encryption mode, a filling mode, offset and a character set are preset in the encryption tool; carrying out block encryption on the plaintext by adopting an AES algorithm, filling an insufficient part by adopting a set filling mode, expressing the plaintext in a square matrix form, and encrypting to form a ciphertext; and transmitting the ciphertext to a corresponding decryption tool, and decrypting the ciphertext by adopting the agreed same key to obtain an original plaintext. The method is simple and effective, and can meet the requirement of ordinary people for protecting daily chat conversation privacy. The method can be widely applied to the technical field of data encryption.

Description

technical field [0001] The present invention relates to the technical field of data encryption, in particular to an encryption method, system, storage medium and computing device based on social platform daily conversations. Background technique [0002] There are many and varied encryption algorithms in the field of information security today, which can be roughly divided into hash algorithms, symmetric encryption algorithms, and asymmetric encryption algorithms. The hash algorithm is also called the hash algorithm, which converts the input of any length into a fixed-length output through the hash algorithm. This fixed-length output is called the "hash value" or "hash value" of the original input message, because This process is irreversible, so hash algorithms are mostly used for signatures. The symmetric encryption algorithm has fast encryption speed and high efficiency, and is the most widely used and most frequently used encryption algorithm. The encryption key and de...

Problems solved by technology

[0004] However, in the daily dialogue scenarios of social platforms, there are also many information leakage situations, and a convenient, fast and effective method is needed to protect the privacy of dialogue information

For example: on a social platform for private conversations, the private conversation between two people may be seen by a third party due to various reasons such as mobile phone pop-ups and forgetting to lo
