ABSTRACT:
A method of packet encryption and decryption that allows for pipelining. The first step is to identify the packets in a message to be encrypted. Then, a unique number is assigned to each packet. A value R is acquired. Then, a first register is initialized. An initialization vector IV is generated. Then, the first register is stepped a user-definable number of times. Then, a packet is selected. R and the unique number are combined. Then, a second register is initialized. A checksum is generated. Then, the packet is divided into blocks. A block is selected. Then, the checksum is combined with the block and designated the checksum. The block is encrypted. Then, the first and second registers are stepped. These steps are repeated for each block. Then, the checksum is encrypted. After the blocks are encrypted, the unique number, IV, the ciphertext of each block, and the encrypted checksum are transmitted. If there are any other packets to encrypt then the steps are repeated.
