Abstract
A method of encoding and encrypting input data (D1) to generate corresponding encoded and encrypted data (E2) is provided. At least a first data block of the input data (D1) is encoded to generate a first encoded data block. The at least first encoded data block is then encrypted using at least one key to provide a first encoded and encrypted data block for inclusion in the encoded and encrypted data (E2). Moreover, a first seed value is generated for use in encrypting a next encoded data block to provide a next encoded and encrypted data block for inclusion in the encoded and encrypted data (E2). Furthermore, a next seed value is generated for use in encrypting a subsequent encoded data block, in a sequential repetitive manner until each data block of the input data (D1) is encoded and encrypted into the encoded and encrypted data (E2).
