Benefits of technology

This solution effectively prevents MITM and replay attacks by ensuring that encryption keys are not reusable, reducing the risk of unauthorized access and simplifying key management, as the dynamic keys are generated and used only for a single encryption event, and the key exchange module ensures secure decryption by only the intended recipient.

Problems solved by technology

The dynamically generated encryption key is not saved after an encryption event, so that the key cannot be produced or reproduced.

Embodiment Construction

[0034]The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes presently contemplated by the inventors of carrying out the invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein.

[0035]The present invention provides a method and apparatus for dynamically generating data encryption keys for encrypting data files and for decrypting encrypted data files via a key exchange method. The present invention provides a method and apparatus for dynamically generating an encryption key for each encryption event. The dynamically generated encryption key is not saved after an encryption event, so that the key cannot be produced or reproduced. Resultantly, a file encrypted with the dynamically generated key is prevented from unauthorized decryption. Thus, the present invention is not substantiall...

Abstract

A method and apparatus for dynamically generating data encryption keys for encrypting data files and for decrypting encrypted data files via a key exchange method is provided. A dynamically generated an encryption key is generated for each encryption event, so that the key cannot be produced or reproduced. A key exchange component of the invention ensures that only an intended recipient has the means to decrypt a file encrypted with the dynamically generated symmetric encryption keys.
