Abstract

Embodiments are directed towards managing data storage for secure storage of shared documents. A user or an application may provide data destined for encryption and a public key. Instruction set information that references at least a seed file that may be installed on the network computer may be generated. An encryption key based on the instruction set information may be generated. Header information that includes the instruction set may be generated. And, the header information may be encrypted using the public key. A secure bundle that includes the public key, the encrypted header information, and the encrypted data may be generated and provided to the user that provided the data and the public key or the application that provided the data and the public key. Decrypting the data included in the secure bundle the above actions are generally performed in reverse.

Claims

1. A method for providing a secure bundle that is employed to manage data storage using a network computer, wherein the secure bundle comprises:

an identifier that is provided to uniquely identify and reference the secure bundle;

a first collection that includes each of a plurality of public keys that correspond to a different party, wherein each party is authorized to employ their corresponding public key to decrypt one or more portions of encrypted file data that is included in the secure bundle;

a second collection that includes one or more headers that correspond to the one or more portions of the encrypted file data, wherein a header is encrypted with a same public key that is employed to encrypt a corresponding portion of the encrypted file data, and wherein each header includes instruction set information, and wherein the identifier, the first collection and the second collection are appended to the encrypted file data; and

wherein the network computer includes one or more processors that perform actions, including;

generating the instruction set information that references a seed file that is installed on the network computer, wherein the seed file is determined from a plurality of seed files based on identifying information that is included in the instruction set information; and

generating one or more encryption keys based on the instruction set information and the pass phrase that is extracted from the seed file, wherein the one or more encryption keys are employed to encrypt the file data, and wherein a signal, provided by a sensor, is used to introduce entropy in the generation of the one or more encryption keys.

2. The method of claim 1, further comprising providing the secure bundle to either the party that provided the one or more portions of the file data and the one or more public keys or an application that provided at least the file data and the one or more public keys.

3. The method of claim 1, wherein the network computer performs further actions, comprising:

launching and executing an encryption engine, on the network computer, to encrypt the file data using the one or more encryption keys.

4. The method of claim 1, wherein the one or more encrypted headers, further comprise one more of seed values, cache values, and metadata, wherein the metadata includes one or more of check sum values, file size information, creation date, the first collection of the one or more public keys, or the identifier.

5. The method of claim 1, wherein the seed file is based on an offset value and a length value that are included in the instruction set information.

6. The method of claim 1, wherein the instruction set information includes one or more of an entity identifier, a platform identifier, or the public key.

7. A system for managing data storage, comprising:

a network computer, comprising;

a transceiver that communicates over the network;

a memory that stores at least instructions; and

one or more processor devices that execute instructions that perform actions on a secure bundle data structure, including;

generating instruction set information that references a seed file that is installed on the network computer, wherein the seed file is determined from a plurality of seed files based on identifying information that is included in the instruction set information; and

generating one or more encryption keys based on the instruction set information and a pass phrase that is extracted from the seed file, wherein the one or more encryption keys are employed to encrypt the file data, and wherein a signal, provided by a sensor, is used to introduce entropy in the generation of the one or more encryption keys; and

wherein the secure bundle data structure comprises;

an identifier that is provided to uniquely identify and reference the secure bundle data structure;

a first collection that includes each of a plurality of public keys that correspond to a different party, wherein each party is authorized to employ their corresponding public key to decrypt one or more portions of encrypted file data that is included in the secure bundle; and

a second collection that includes one or more headers that correspond to the one or more portions of the encrypted file data, wherein a header is encrypted with a same public key that is employed to encrypt a corresponding portion of the encrypted file data, and wherein each header includes instruction set information, and wherein the identifier, the first collection and the second collection are appended to the encrypted file data, wherein the secure bundle is presented to at least one provider of at least one portion of the file data and at least one public key.
