Abstract
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.
Claims20
A method of cryptographic security, comprising:
- receiving, by a hardware processor, a blade identifier associated with a blade server installed in a chassis;
- receiving, by the hardware processor, a host bus adapter identifier associated with a host bus adapter;
- and
- generating, by the hardware processor, a cryptographic affinity in response to hashing the blade identifier and the host bus adapter identifier using an electronic representation of a hashing algorithm.
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 blade identifier sent from a blade server installed in a chassis;
- retrieving a host bus adapter identifier associated with a host bus adapter interfacing with the blade server;
- generating a cryptographic affinity in response to hashing the blade identifier and the host bus adapter identifier using an electronic representation of a hashing algorithm;
- and
- comparing the cryptographic affinity to access electronic data stored by the blade server.
A memory device storing instructions that when executed cause a hardware processor to perform operations, the operations comprising:
- receiving a blade identifier sent from a blade server installed in a chassis;
- retrieving a host bus adapter identifier associated with a host bus adapter interfacing with the blade server;
- generating a cryptographic affinity in response to hashing the blade identifier and the host bus adapter identifier using an electronic representation of a hashing algorithm;
- and
- authorizing access to electronic data stored by the blade server based on the cryptographic affinity.
