System and method for key management in computing clusters
View Patent ↗Cryptographic affinities are generated to improve security in server environments. One or more cryptographic affinities protect electronic data stored within a blade server. The cryptographic affinities are generated based on hashing a unique blade identifier and a unique identifier assigned to a network interface. The cryptographic affinities thus govern read, write, and other access operations. If any cryptographic affinity fails to match historical observance, then access to the blade server may be denied.
1. A method of cryptographic security, comprising:
receiving, by an Ethernet controller, a read/write operation associated with a blade server installed in a chassis;
receiving, by the Ethernet controller, a blade identifier associated with the blade server installed in the chassis;
receiving, by the Ethernet controller, a host bus adapter identifier associated with a host bus adapter that communicates with the blade server installed in the chassis;
generating, by the Ethernet controller, a cryptographic affinity by hashing the blade identifier and the host bus adapter identifier using an electronic representation of a hashing algorithm;
comparing the cryptographic affinity to a historical value; and
in response to the cryptographic affinity failing to match the historical value, denying the read/write operation associated with the blade server.
2. The method of claim 1 , further comprising storing the cryptographic affinity in an electronic database.
3. The method of claim 1 , further comprising storing the cryptographic affinity in an electronic database, the electronic database electronically associating the cryptographic affinity and the blade identifier.
4. The method of claim 1 , further comprising retrieving the cryptographic affinity in response to a failure of at least one of the blade server and the host bus adapter.
5. The method of claim 1 , further comprising storing the cryptographic affinity in an electronic database, the electronic database electronically associating the cryptographic affinity to the blade identifier and to the host bus adapter identifier.
6. The method of claim 1 , further comprising denying an access to the blade server based on the cryptographic affinity.
7. The method of claim 1 , further comprising comparing the cryptographic affinity to an electronic database that stores historical values of the cryptographic affinity.
8. An apparatus, comprising:
a hardware processor; and
a memory device storing instructions, the instructions when executed causing the hardware processor to perform operations, the operations including:
receiving a read/write operation associated with a blade server installed in a chassis;
receiving a blade identifier associated with the blade server installed in the chassis;
receiving a host bus adapter identifier associated with a host bus adapter interfacing with the blade server;
generating a cryptographic affinity by hashing the blade identifier and the host bus adapter identifier using an electronic representation of a hashing algorithm;
comparing the cryptographic affinity to a historical value; and
in response to the cryptographic affinity failing to match the historical value, denying the read/write operation associated with the blade server.
9. The apparatus of claim 8 , wherein the operations further comprise storing the cryptographic affinity in an electronic database.
10. The apparatus of claim 8 , wherein the operations further comprise storing the cryptographic affinity in an electronic database, the electronic database electronically associating the cryptographic affinity and the blade identifier.
11. The apparatus of claim 8 , wherein the operations further comprise storing the cryptographic affinity in an electronic database, the electronic database electronically associating the cryptographic affinity and the host bus adapter identifier.
12. The apparatus of claim 8 , wherein the operations further comprise storing the cryptographic affinity in an electronic database, the electronic database electronically associating the cryptographic affinity to the blade identifier and to the host bus adapter identifier.
13. The apparatus of claim 8 , wherein the operations further comprise receiving a request to read an electronic data stored by the blade server.
14. The apparatus of claim 13 , wherein the operations further comprise denying the request to read the electronic data.
15. The apparatus of claim 8 , wherein the operations further comprise receiving a request to write an electronic data to the blade server.
16. The apparatus of claim 15 , wherein the operations further comprise denying the request to write the electronic data.
17. A memory device storing instructions that when executed cause a hardware processor to perform operations, the operations comprising:
receiving a read/write operation associated with a blade server installed in a chassis;
receiving a blade identifier sent from the blade server installed in the chassis;
retrieving a host bus adapter identifier associated with a host bus adapter interfacing with the blade server;
generating a cryptographic affinity by hashing the blade identifier and the host bus adapter identifier using an electronic representation of a hashing algorithm; and
if the cryptographic affinity fails to match the historical value, then denying the read/write operation associated with the blade server.
18. The memory device of claim 17 , wherein the operations further comprise denying an access to the blade server.
19. The memory device of claim 17 , wherein the operations further comprise denying a read operation.
20. The memory device of claim 17 , wherein the operations further comprise denying a write operation.
