The coding principle of HCS301 encoder is as follows:
HCS301, before using, must produce a unique encryption key.Key production process: produce algorithm through key by works code together with series number and form unique Crypted password, then write EPROM in sheet.Works code claims again serial codes or manufacturer's code, and length is 64Bit.Each manufacturer is all not identical, and it is for generation of the unique-encryption key corresponding with each encoder.Works code is the key of whole system safety, answers standardized administration, preserves.As works code is divulged a secret, whole system can be sayed without any fail safe.Series number is 28Bit, corresponding to each encoder, can be used as user code.
HCS301 cataloged procedure is by former code, and encryption key and synchronous code etc. are through KEELOQ(important safety encipher decryption technology) after algorithm for encryption, produce the highly confidential rolling code of 32Bit.While transmission due to the complexity of KEELOQ algorithm and 16 bit synchronization codes, all to upgrade, therefore each transmission code is all completely different with last code at every turn.Only just may repeat after 216 times in transmission, calculate to transmit 10 codes every day, the time interval is 18 years.
In HCS301 sheet, have 192Bit (16 × 12) EEPROM, for storage encryption key, sequence number synchronization value and out of Memory all need to operate on it before using HCS300/301 and among using, and before using, need it to programme.For regent, only in quite short time, just can carry out read back check in programming after EEPROM, be taboo read states At All Other Times.Among use, read EEPROM information encryption, produce and send code, and upgrade synchronization value.
The signaling information of HCS301 is made up of several parts, and the code word of each signaling starts with guidance code mark and leader, is then rolling code and fixed code part, is finally each guard time sending.Rolling code part is 32Bit enciphered data, and fixed code part is 34Bit, comprises mode bit, and function digit and 28 series numbers amount to nearly 7.38 × 1019 kinds of code combination.
HCS301 sends 66 coded datas in the time that each button is pressed, and due to rolling code and fixed code two parts composition, rolling code part is by 4 key-press status, 2 counting overflow positions, and 10 discrimination bits and 16 bit synchronization values produce through encrypting.Fixed code is by 28 series numbers, and 4 key-press status and 2 mode bits form.
