Password encryption and multi-channel transmission method

Abstract

This invention relates to one order transmission method by use of secret sharing or visual cryptography or multi-signal channel suitable for order transmission, which Uses secret sharing or visual cryptography to code the order into multiple sub orders to add the difficulty of stealing orders as the single order can not get secret order any information; the legal user owns all orders through simple computation or transparent film to get original order.

Description

technical field [0001] The invention relates to a multi-channel password transmission method using secret sharing or visual cryptography. Its classification number is: H04K1 / 00, H04L9 / 00 Background technique [0002] In the current market, users want to apply for a certain service, such as applying for a bank credit card, purchasing a mobile phone SIM card (also including applying for an online account, applying for an online stock trading account) and other services. Here comes a big security risk. In addition, since the application for such services has relatively small transaction volume and does not involve ordinary computer operations, it is not necessary to equip each application user with a dedicated computer for each password transmission, let alone a dedicated encryption machine. Considering that users who apply for such services usually do not have cryptography knowledge, it is difficult to ensure that ordinary users can use it correctly even if they are equipped...

For practical applications, the (n, n) secret sharing scheme may also be used. Its principle is similar to the (2, 2) scheme, the difference is that a secret password is split into n sub-passwords, and only the n The secret password can only be obtained if all sub-passwords are obtained, and any information about the secret password cannot be obtained without any sub-password
