Abstract
Securing and accessing digital data by encrypting the digital data with a digital key. The encrypted data is striped across a plurality of physical data storage devices. A key is required to access the digital data. This is done by applying the digital key access the encrypted data across all of the physical data storage devices when all of the physical data storage devices are simultaneously present.
Claims12
A method of securing and accessing digital data comprising:
- a) encrypting the digital data with a digital key;
- b) striping said encrypted data across a plurality of physical data storage devices requiring said key for access to the digital data;
- and
- c) applying said digital key to access said encrypted data when all of said physical data storage devices are simultaneously present.
A data storage system comprising a plurality of separate, individual memory devices for striped storage of encrypted digital data;
- a) means for simultaneously applying a digital key to access said encrypted data when all of said physical data storage devices are simultaneously present;
- and
- b) means for simultaneously reading said encrypted data only when all of said physical data storage devices are simultaneously present.
A program product comprising computer readable program code for use with a data storage system comprising a plurality of separate, individual memory devices for striped storage of encrypted digital data, and having means for simultaneously applying a digital key to access said encrypted data when all of said physical data storage devices are simultaneously present;
- and means for simultaneously reading said encrypted data only when all of said physical data storage devices are simultaneously present, said program code causing said data storage system to secure and access digital data by a method comprising:
- a) encrypting the digital data with a digital key;
- b) striping said encrypted data across a plurality of physical data storage devices requiring said key for access to the digital data;
- and
- c) applying said digital key to access said encrypted data when all of said physical data storage devices are simultaneously present.
