Abstract:
A system and method are provided for the secure sharing of information across and open network and for performing management of keys used for encrypting and decrypting data.

Claim (Index 1):
A smartkey-based computer file access system, said system including:\n a user computer system operating a smartkey encryption/decryption application, wherein said smartkey encryption/decryption application receives a smartkey name data; a first user password data; a second user password data; a first user public key data; a second user public key data; wherein said smartkey encryption/decryption application forms a smartkey electronic data structure including: said smartkey name data in unencrypted form; a first user encrypted master key data, wherein said first user encrypted master key data is formed by said smartkey encryption/! decryption application by determining a master key data derived from random data and encrypting said master key using said first user public key data; a second user encrypted master key data, wherein said second user encrypted master key data is formed by said smartkey encryption/decryption application by encrypting said master key using said second user public key data; a first user password-accessible public key data comprising said first user public key data encrypted by said first user password; a second user password-accessible public key data comprising said second user public key data encrypted by said second user password; wherein said smartkey encryption/decryption application receives an electronic data file, wherein said smartkey encryption/decryption application forms a session key associated with said electronic data file and encrypts said data file to form an encrypted data file using said session key, wherein said smartkey encryption/decryption application: encrypts said session key using said first user encrypted master key data and stores the result as a first user encrypted session key data in said smartkey electronic data structure, encrypts said session key using said second user encrypted master key data and stores the result as a second user encrypted session key data in said smartkey electronic data structure, a smartkey provider computer system, wherein said smartkey encryption/decryption application initiates the transmission of said smartkey electronic data structure from said user computer system to said smartkey computer provider system, wherein said smartkey electronic data structure is stored at said smartkey computer provider system; and a second user computer system operating an instance of said smartkey encryption/decryption application, wherein said second user computer system receives: a target smartkey name data; said encrypted data file; and a user password data representing a user to be allowed to decrypt said encrypted data file, wherein said second computer system transmits said target smartkey name data to said smartkey provider system, wherein said smartkey provider system searches a plurality of stored smartkey electronic data structures, identifies a smartkey electronic data structure including smartkey name data matching said target smartkey name data, and transmits said smartkey data structure to said second computer system, wherein said second computer system uses said user password data to decrypt said first user password-accessible public key data to obtain said first user public key data, wherein said second computer system uses said first user public key data to decrypt said first user encrypted master key data to obtain said master key data, wherein said second computer system uses said master key data to decrypt said first user encrypted session key data to obtain said session key data, and wherein said second computer system uses said session data to decrypt said encrypted data.
