An Encrypting Algorithm for Magnetic Resonance Systems

초록

An encrypting algorithm for magnetic resonance systems is proposed to enhance the encrypting capability of the systems. In addition to encryption methods, randomization methods are used to transmit magnetic resonance system images. The randomization of images can be easily and quickly performed using random images of the same resolution size to randomize the image itself without the need for a symmetric key or public key for encryption. Therefore, we propose a mathematical randomization method that can achieve a performance similar to that of a random bit generator used in the existing Windows operating system. This method is suitable for generation in embedded systems or low-spec hardware that does not have an operating system installed. Random bits are extracted using the proposed irrational numbers and modified periodic functions. We compared the random bits of the proposed method with the random bit generator of the Windows operating system when using the NIST-SP 800-90B standard to evaluate randomness. Finally, we show that the randomness of the random bits generated by the proposed method is similar to that of existing methods.
