  • System and method for efficient and secure implementation of LS-Designs
    Patent number: 10992470
    Abstract: The invention provides implementations of the block cipher in resource-constrained ARM devices that may be applied to both 32-bit and 64-bit versions of side-channel resistant and vectorized code and provides improves both efficiency and compactness by using of algorithmic techniques and features specific to a target platform. Specifically, an unprotected 32-bit implementation improves speed while reducing code size and a vectorized implementation improves performance and speed the implementation of block cipher.
