SCRAMBLING BIT TRANSMISSIONS

摘要

A bus communicates bits in parallel between a transmitter and receiver. A selected set of bits has its bits scrambled. Scrambling the bits includes assigning two or more bits of the selected set of bits to atypical lanes of the bus. By scrambling the bits, the order in which the bits of the selected set of bits are ready by a processer are obscured. The set of bits is transmitted to the receiver with one or more delays. The delays are on one or more of the lanes of the bus. The delays indicate the order of the bits. The receiver is configured to use the delays to identify the order of the bits and unscramble the set of bits.

1. A method for securing data transmissions, the method comprising:
scrambling a transmission of a selected set of bits over a bus between a transmitter and a receiver, wherein the bus communicates bits in parallel, wherein scrambling the selected set of bits includes assigning bits of the selected set of bits to an atypical set of lanes of the bus such that an order of the bits in which the selected set of bits is read by a processor is obscured; and transmitting the selected set of bits to the receiver with one or more delays on one or more lanes of the atypical set of lanes, wherein the one or more delays indicate the order of the bits, wherein the receiver is configured to use the one or more delays to identify the order of the bits.
