System for communicating program data between a first device and a second device
First Claim
1. A system for communicating program data between a first device and a second device, the system comprising:
- a first device configured to;
disassemble a first program file comprising program data into a first at least one logical data unit;
partition each of said first at least one logical data unit into a first at least one protocol data unit, the format of said first at least one protocol data unit defined by a communication protocol and including a payload portion;
compute a first fingerprint over the payload portion of said first at least one protocol data unit of said first at least one logical data unit; and
send a second program file comprising said program data and one or more members of the group comprising said first fingerprint and a first authentication code based at least in part on said first fingerprint;
a second device configured to;
receive said second program file and at least one of said group;
disassemble said program data into a second at least one logical data unit; and
partition each of said second at least one logical data unit into a second at least one protocol data unit; and
a third device comprising a memory, said third device configured to;
receive at least one of said group and said second at least one protocol data unit;
compute a second fingerprint over the payload portion of said second at least one protocol data unit; and
commit said program to said memory based at least in part on whether said one or more members match said second fingerprint or a second authentication code based at least in part on said second fingerprint.

Abstract
A system for communicating program data between devices includes a first device configured to disassemble a program file comprising program data into at least one logical data unit, partition each logical data unit into at least one protocol data unit and compute a first fingerprint over the payload portion of the protocol data units. The first device is also configured to send the protocol data units and at least one member of the group comprising the first fingerprint and a first authentication code based on the first fingerprint to a second device. The second device is configured to compute a second fingerprint over the payload portion of the protocol data units and to commit the program to a memory based on whether the at least one member matches the second fingerprint or a second authentication code based on the second fingerprint.
