Analyze the principle and advantages of floating password electronic lock technology What is a floating password (FloatingID)? The floating password technology is that the password is automatically replaced each time the key contacts the lock body. The digital security system technology with irregular passwords and non-replicable is floating cryptography. Different traditional password locks, the traditional password lock password does not change every time it is used, so there is a danger of being stolen. The floating cipher technology uses two sets of passwords, both fixed and floating, stored in a semiconductor (card) key (281 trillion fixed cipher suites) and a lock body (4.2 billion floating cipher suites), each time it is used. The password in the key is entered into the lock system for confirmation and automatic replacement. In case the key is stolen and copied, since the password in the floating cipher group previously used by the holder has changed, even if the fixed password is the same, it will not be recognized by the system, so this copy is meaningless (this probability is equivalent to one person) Two thousand times the probability of winning the first prize in the lottery.) The origin of the floating password The floating password technology was developed by the founder of Korea Easy Insurance Co., Ltd., Mr. He Zaihong, when he worked at the Daewoo Electronics Co., Ltd. in Korea. At that time in Seoul, the news reported that someone had copied the mechanical key to steal, and used the stolen finance to supply three children to study abroad. After being arrested by the police, they found that they were women in their 50s. After seeing the report, President He Honghong saw the report. It was found that the copying of mechanical keys poses a great threat to family property, so the chairman of the river thought about whether it was possible to develop a password that changed when the door was opened, so that it would not be stolen. Based on this idea, a floating password technology was developed. This technology has obtained patent technology certification in Korea, the United States, Hong Kong and Taiwan. Advantages of floating cryptography • Don't worry about the key being copied The key of Yale electronic lock with floating password, don't worry about being copied, because the combination of key and lock body is 281 megabytes fixed cipher group * 4.2 billion floating cipher group, the password will change every time, so there is basically no copy Key and the possibility of guessing the password, • Don't worry about lost keys being used by others When the mechanical key of the general mechanical lock is lost, in order to prevent theft by others, it is necessary to replace the entire lock or lock; however, for the Yale electronic lock using the floating password technology, there is no such concern, if the card key If you lose it, you only need to reset the remaining card key. The lost card key is automatically cancelled and can no longer be used. Therefore, the security of use is guaranteed.
