- Abstract
- The article describes the structure of an encryption device implementing cryptographic data processing in accordance with the Magma algorithm with protection against information leakage through the side channels and increasing the reliability of cryptographic operations. Protection against information leakage by side channels is provided by creating an optimal masking interference. The optimal masking interference is created by simultaneous synchronous data processing in accordance with the "Magma" algorithm in the direct representation and in the inverted representation. The increase in the reliability of cryptographic operations is achieved due to the fact that in the encryption device, data is processed simultaneously in accordance with the Magma algorithm in direct representation and in inverted representation, followed by a comparison of the processing results in direct and inverse representation with each other. The proposed structure of the encryption iteration block allows the introduction of an external one-bit feature to switch the encryption iteration device to work with data in a direct or inverted representation.
