Techniques are provided for security key integrity verification using inventory certificates. One method comprises receiving a user request to perform an action: obtaining an inventory certificate associated with a device; extracting a security key identifier from a security key corresponding to the device; validating the security key by comparing the extracted security key identifier to a security key identifier in the inventory certificate; and authorizing a performance of the action based on a result of the comparison. A validity of the inventory certificate may be evaluated (e.g., by evaluating a signature associated with the inventory certificate). The inventory certificate may be stored in a secure memory of the device prior to a delivery of the device to a purchaser of the device.

Security key integrity verification using inventory certificates

Secure communications are established in a non-secure environment between virtual machines configured as nodes of a virtual machine cluster having a virtual scale-out architecture without user intervention. When a new virtual cluster node is automatically and dynamically created and deployed by a virtual cluster master node, the master node embeds in a common image from which the new node is created an initial secret key for establishing initial trusted communications between the new node and the master node. The master node then passes a permanent secret key to the new node, opens an OpenSSL connection for creating a public key infrastructure, and signs the new node's CSR with its own public and private keys and sends the signed certificate to the new node.

Securing cluster communications in a non-secure network

Plaintext data is encrypted to produce ciphertext which is transmitted along with a hash of the plaintext data and corresponding metadata comprising an initialization vector and information about the encryption key version used to encrypt the plaintext data to a backend storage system. The encrypted ciphertext is deduplicated at the backend storage system (without first decrypting it) using the hash and stored based upon the metadata.
