Abstract
A method for decrypting a serial transmission signal includes the following steps. First, the serial transmission signal including a serial data signal and a serial clock signal is received. Then, m bits are sequentially read from the serial data signal according to the serial clock signal. Next, values corresponding to the m bits are generated. Thereafter, each value is added to a content value of a register by an addition operation to obtain an addition result, and then the addition result replaces the content value and is stored in the register.
Claims14
A method for decrypting a serial transmission signal, the method comprising:
- receiving the serial transmission signal, which comprises a serial data signal and a serial clock signal;
- sequentially reading m bits from the serial data signal according to the serial clock signal;
- generating values corresponding to the m bits;
- adding each of the values to a content value of a register by an operation of addition to obtain a result of addition, and then replacing the content value with the result of addition and storing the result of addition to the register;
- and
- decrypting the result of addition stored in the register and performing a corresponding process.
A method for decrypting a serial transmission signal applied to a receiving terminal, the method comprising:
- receiving the serial transmission signal, which comprises a serial data signal and a serial clock signal;
- determining whether a logic level of the serial clock signal is equal to a default value;
- reading a bit from the serial data signal when the logic level of the serial clock signal is equal to the default value;
- generating a value corresponding to the bit;
- adding the value and a content value of a register by an operation of addition to obtain a result of addition, and replacing the content value with the result of addition and storing the result of addition into the register;
- and
- decrypting the result of addition stored in the register and performing a corresponding process.
