Abstract
A system for the exchange of cryptographic keys includes a first peer source and a second peer system. The first peer source is capable of displaying a cryptographic key adapted to at least one of encrypt and decrypt electronic information. In turn, the second peer system capable of capturing the cryptographic key. Advantageously, the second peer system is capable of capturing the cryptographic key such that a user of the second peer system is capable of visually confirming receipt of the cryptographic key from the first peer source. For example, the user can visually confirm receipt of the cryptographic key by situating the first peer source and second peer source within a field of view of a user of the second peer system as the second peer system captures the cryptographic key.
Claims30
A system for the exchange of cryptographic keys comprising:
- a first peer source capable of displaying a cryptographic key adapted to at least one of encrypt and decrypt electronic information;
- and
- a second peer system capable of capturing the cryptographic key, wherein the second peer system captures the cryptographic key such that a user of the second peer system is capable of visually confirming receipt of the cryptographic key from the first peer source.
A method of exchanging cryptographic keys comprising:
- displaying a cryptographic key adapted to at least one of encrypt and decrypt electronic information, wherein the cryptographic key is displayed from a first peer source;
- and
- capturing the cryptographic key such that receipt of the cryptographic key from the first peer source is visually confirmable.
A peer source for providing a cryptographic key, the peer source comprising:
- a key generator capable of generating a cryptographic key adapted to at least one of encrypt and decrypt electronic information;
- and
- a key exchange element electrically coupled to the key generator, wherein the key exchange element is capable of displaying the cryptographic key such that the cryptographic key is capable of being detected by a second peer system, and wherein the cryptographic key is displayed such that a user of the second peer system is capable of visually confirming receipt of the cryptographic key from the first peer source.
A peer system for receiving a cryptographic key, the system comprising:
- an image capture device capable of capturing a cryptographic key adapted to at least one of encrypt and decrypt electronic information, wherein the image capture device is capable of capturing the cryptographic key displayed by a first peer source, wherein the image capture device is capable of capturing the cryptographic key such that a user of the peer system is capable of visually confirming receipt of the cryptographic key from the first peer source.
