Encrypted digital keyboard and encryption method

Abstract

The invention relates to a keyboard, and particularly relates to an encrypted digital keyboard and an encryption method. The encrypted digital keyboard comprises a keyboard base, a handover switch, a handover lock, a lock hole, a connecting rod, center contacts and side contacts, wherein the side contacts comprise upper contacts, lower contacts, left contacts and right contacts; the handover switch is connected with the handover lock and the lock hole; the center contacts and the side contacts are separately installed in the centers and at the upper, lower, left and right positions inside keys. The handover switch is connected with the handover lock and the lock hole; after the handover switch is turned on, the center contacts are locked, and the side contacts work to control generation and input of key surface letters, digits and punctuations; after the handover switch is turned off, the side locks are locked, and the center contacts work to recover the function of a common keyboard; by improving the common keyboard, the limitation and the simplicity of ten digit codes from 0 to 9 are broken; meanwhile, since only the internal structure is improved, the method does not conflict with the original technology, is more convenient to implement and also thoroughly solves the problems of low security of the common keyboard and the like.

Description

technical field [0001] The invention relates to a keyboard, in particular to an encrypted numeric keyboard and an encryption method. Background technique [0002] With the development of society and the advancement of science and technology, digital generation input technology has been applied to various fields, which greatly meets people's needs, but it also has certain shortcomings. For example, the existing codes usually use the ten Although the method of generating and inputting is simple and easy, it is also easy to be stolen and cracked. The reason is that it is encoded with 0-9 numbers, which has few code elements, inconvenient code length, and short code. Although the form is simple, But it cannot be expanded, it can only be added horizontally, and cannot be extended vertically. [0003] In some special industries or departments, due to the particularity of the work or occasion, certain confidentiality work is required, but because the current keyboard layout is too...
