System and method for encrypted communications between electronic devices
First Claim
1. A system for encrypted communications, comprising:
- a first transponder including a first memory arrangement which stores a first key; and
a second transponder including a second memory arrangement and having an access to a second key, wherein the first transponder generates a first message to the second transponder, the first transponder encrypting the message using a randomization key to generate a second message, the first transponder encrypting (a) the second message and (b) one of the randomization key and an index to the randomization key using the first key to generate a third message, and wherein the second key is capable of decrypting the third message.

Abstract
Described is a system and method for encrypted communications. The system may include first and second transponders. The first transponder has a first memory arrangement that stores a first key. The second transponder includes a second memory arrangement and has an access to a second key. The first transponder generates a first message for delivery to the second transponder, and encrypts the first message using a randomization key to generate a second message. Then, the first transponder encrypts (a) the second message and (b) one of the a randomization key corresponding index using the first key to generate a third message. The second key may decrypt the third message.

21. A method for encrypted communications, comprising the steps of:
-
generating a first message by a first transponder for delivery to the second transponder, the first transponder including a first memory arrangement which stores a first key, the second transponder including a second memory arrangement and having an access to a second key;
encrypting the first message using a randomization key to generate a second message by the first transponder; and
encrypting (a) the second message and (b) one of the a randomization key and a corresponding index using the first key to generate a third message by the first transponder, wherein the second key is capable of decrypting the third message. - View Dependent Claims (22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
