Disclosed are a limited one-way transformation and encryption/decryption application method, device and circuit for gibberish text. The limited one-way transformation method for gibberish text comprises: conducting one-way transformation on initial gibberish text and then conducting an exclusive OR operation on same and a message, and limiting the number of times for the initial gibberish text to participate in the one-way transformation. The limited one-way transformation method for gibberish text of the present invention is an encryption/decryption method for in essence replacing speed with bandwidth, i.e. replacing the encryption/decryption speed with a small amount of bandwidth. Compared with the traditional standard encryption/decryption method, the method of the present invention only needs to consume a small amount of bandwidth, and can improve the encryption/decryption speed up to ten times or even one hundred times on the premise of guaranteeing the security of data. Moreover, the present invention is simple to implement, and thus can be widely applied to the storage and transmission of a large volume of data. |
