Abstract

A method for encryption of blocks of data is provided including the steps of: encrypting a block of data using a current random number generated for the block of data; encoding the current random number using one or more of a set of previous random numbers, each of the set of previous random numbers having been used to encrypt a previously sent block of data; and transmitting the encrypted block of data with the one or more versions of the encoded current random number, each version for a different one of the previous random numbers. A method for decryption of blocks of data is provided including the steps of: receiving an encrypted block of data with the one or more versions of an encoded current random number, each version for a different one of the previous random numbers; selecting one of a set of previously received blocks of data for which the random number is available; decoding the current random number using the random number of the selected previously received block of data; and decrypting the received encrypted block of data using the decoded current random number.
