Title:
METHODS AND APPARATUS FOR SECURE AND EFFICIENT IMPLEMENTATION OF BLOCK CIPHERS
Document Type and Number:
WIPO Patent Application WO/2018/188002
Kind Code:
A1
Abstract:
A method of and apparatus for executing a cryptographic cipher is described. The method includes acts of receiving a first finite field of data and key value represented by a first encryption standard including a first and second operation, transforming the first finite field of data and key value into a second finite field of data and key value represented by a second encryption standard, transforming the first operation and the second operation into a first modified operation and a second modified operation represented by the second encryption standard, executing the first modified operation on the second finite field of data and key value to generate a third finite field of data, executing the second modified operation on the third finite field of data to generate a fourth finite field of data, which is transformed into a fifth finite field of data represented by the first encryption standard.
