International Classification:

G06F 15/177

US Classification:

713 2, 713 1, 713100

Abstract:

Abstract:

A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser may split or share a data set into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting an original data set into portions of data that may be communicated using one or more communications paths. Secure workgroup communication is supported through the secure distribution and management of a workgroup key for use with the secure data parser.

Appl. No.:

13/477306

Inventors:

Matthew Daniel Green - Baltimore MD, US

Assignee:

ZEUTRO, LLC - Baltimore MD

International Classification:

H04L 9/08

US Classification:

380278

Abstract:

Functional encryption (FE) ciphertext is transformed into partially-decrypted (PD) ciphertext. The PD ciphertext has a shorter bit length than the FE ciphertext, or the decryption time of the PD ciphertext is less than the decryption time of the FE ciphertext. The FE ciphertext can be an attribute-based encryption ciphertext. The transformation can be performed with a transformation key generated by an authority with a master key or by a user with a decryption key. The transformation can also be performed, without a transformation key, based on unencrypted components of the FE ciphertext and on auxiliary information associated with the unencrypted components of the FE ciphertext. The PD ciphertext can require less transmission time across a network than the FE ciphertext. The PD ciphertext can require less time to decrypt than the FE ciphertext, particularly when the computational resources performing the decryption are limited.
