Method and system for securing network data
View Patent ↗Method and system for storing data in a storage device accessible through a storage area network is provided. The method includes receiving data from a host system; generating a first encryption key for encrypting data information that describes the received data; generating a second encryption key that encrypts the first encryption key and the encrypted data information; generating an encryption packet that includes the second encryption key, the first encryption key and the data information; storing the encryption packet at one or more memory locations; and periodically refreshing the encryption packet without periodically encrypting the received data for securely storing the received data.
1. A method for storing data in a storage device accessible through a storage area network, comprising:
receiving the data from a host system;
encrypting the data and storing the encrypted data in the storage device:
generating a first encryption key for encrypting data information that describes the received data;
generating a second encryption key that encrypts the first encryption key and the data information;
generating an encryption packet that includes the second encryption key, the first encryption key and the data information;
storing the encryption packet at one or more memory locations; and
periodically regenerating the encryption packet without periodically re-encrypting the encrypted data.
2. The method of claim 1 , wherein an encryption device receives the data from the host system.
3. The method of claim 2 , wherein a key generator module in the encryption device generates the first encryption key, the second encryption key and the encryption packet.
4. The method of claim 2 , wherein the encryption packet is stored in the encryption device and a storage controller.
5. The method of claim 1 , wherein the data information includes logical unit information (LUN) and logical block address (LBA) information.
6. A system for securely storing data, comprising:
a host system for writing and reading the data from a storage device that is accessible through a storage area network;
an encryption device that receives the data from the host system and (a) encrypts the data; (b) generates a first encryption key for encrypting data information that describes the data received from the host system; (c) generates a second encryption key that encrypts the first encryption key and the data information; and (d) generates an encryption packet that includes the second encryption key, the first encryption key and encrypted data information; wherein the encryption packet is stored in a memory for the encryption device; and the encryption device periodically regenerates the encryption packet without periodically re-encrypting the encrypted data for securely storing the received data and
a storage controller that interfaces with at least one storage device and the encryption device to store the encrypted data in the at least one storage device, and also stores a copy of the encryption packet.
7. The system of claim 6 , wherein a key generator module in the encryption device generates the first encryption key, the second encryption key and the encryption packet.
8. The system of claim 6 , wherein the data information includes logical unit number (LUN) information and logical block address (LBA) information.
9. An encryption device, comprising:
an interface for receiving data from a host system;
a processor for encrypting the data;
a key generator module that (a) generates a first encryption key for encrypting data information that describes the data received from the host system; (b) generates a second encryption key that encrypts the first encryption key and the data information; and (c) generates an encryption packet that includes the second encryption key, the first encryption key and the encrypted data information; and the encryption packet is stored in a memory for the encryption device; wherein the encryption device periodically regenerates the encryption packet without periodically re-encrypting the encrypted data; and
a storage controller interface for communicating with a storage controller that controls storage of the encrypted data on one or more storage devices accessible to the host system.
10. The encryption device of claim 9 , wherein the encryption packet is also stored in a storage controller that interfaces with at least one storage device and the encryption device.
11. The encryption device of claim 9 , wherein the storage area network is a Fibre Channel based system.
12. The encryption device of claim 9 , wherein the data information includes logical unit information (LUN) and logical block address (LBA) information.
