Bitwise operators are used to perform bitwise operations on bit patterns. Some of the bitwise operators are discussed as follows: Bitwise AND (&) performs ANDing operation between the bit patterns of the data provided on the left- and right-hand sides of the operator.Bitwise OR (|) performs bitwise OR of two numbers provided on the left- and right-hand sides of the operator.Bitwise operators such as bitwise XOR (^) and bitwise not (~) are used to perform exclusive OR and not respectively.

Notably, deploying IoT data facilitates track and tracing of the container at the terminals and gates. Nevertheless, the security of the container and the whole supply chain relies heavily on the authenticity of the PubSensorsID. The low-cost sensors in the market, such as RFID tags, lack the computational capabilities to perform complex cryptographic functions. In the literature of cryptography, the bitwise operation has been identified as one of the efficient ways to overcome this limitation (Liu et al. 2019). Among various bitwise operations (e.g. AND, OR, or binary inner-product operations), the bitwise XOR operation has higher security due to its one-to-one property (Alomair and Poovendran 2008).

There are 11 numerical operations in the C language, four of which are bitwise operations: &, |, ^, ~ (bitwise operation in this paper is especially referred to logic-based operation, not including the shift operations: <<, >>). According to the statistics of 16 open source projects, nearly 150,000 lines of code, the bitwise operation accounts for 12% in all numerical operations and the probability of occurring in the program is 2.7% (see attached Table 1 for detail).
