  • Patent number: 12267421
    Abstract: Post quantum secure network communication is provided. The process comprises sending, by a client in a first computing cluster, an outbound message to a quantum safe cryptographic (QSC) proxy server in the first computing cluster, wherein the outbound message is addressed to a target server in a second computing cluster. The QSC proxy server initiates a QSC transport layer security (TLS) connection with an ingress controller in the second computing cluster, wherein the ingress controller comprises a QSC algorithm. The QSC proxy server transfers the message to the ingress controller via the QSC TLS connection, and the ingress controller routes the message to the target server in the second computing cluster via a non-QSC connection.

  • Patent number: 12160511
    Abstract: Hybrid encryption of imported key material is provided. A request to import key material is received from a user system. In response to the request, two public keys are sent to the user system. The two public keys include a classical cryptography (CC) public key and a quantum-safe cryptography (QSC) public key. At least one public key of the two public keys is retrieved from a hardware security module (HSM). Hybrid-encrypted key material is received from the user system. The hybrid-encrypted key material is key material that has been encrypted using the two public keys. The key material, at least partially encrypted by the at least one public key, is sent to the HSM.

  • Patent number: 11575508
    Abstract: Methods and systems for unified HSM and key management services are disclosed. According to certain embodiments, an encryption service request is issued by a client instance to a key management service (KMS) logic in a KMS cloud instance. The KMS logic parses the request to verify authorization for the request, identify the instance ID, and provide additional information to the request needed by hardware security management (HSM) middleware and hardware. A router receives the request from the KMS logic and routes the request to a service based on the instance ID, that transfers the request to HSM middleware. The HSM middleware parses HSM type from the request, translates the request to HSM vendor-specific instructions and routes the translated request to an HSM. The HSM according to certain embodiments is in a cloud computing environment separate from the KMS cloud instance, and in some embodiments the HSM is on-prem at a physical client site.
