In one embodiment, the method comprises accepting a request to generate at least one key in an online data signing system; generating, in a hardware security module communicatively coupled to the online data signing system, a first key Kas a temporary object; encrypting, by the hardware security module, the first key Kaccording to a wrapping key Kw to produce an encrypted first key E[K]; storing the encrypted first key; and providing a second key Kassociated with the first key Kto a user device communicatively coupled to the online data signing system.

Optimized key management for data signing systems

A system and method for provisioning confidential data such as unique credentials is described. The technique initializes a whitebox cryptographic software module to a particular PKI client to soft-lock whitebox cryptographic operations to the particular PKI client and uniquely encrypting the credentials with a node-locking key (NLK) derivable from a digital certificate.

Method and apparatus for provisioning node-locking confidential data

Systems and methods for PKI certificate and key allocations to wireless base station radio units are provided. In one embodiment, a system for obtaining PKI credentials for a remote unit for a wireless base station, the system comprises: a remote unit, the remote unit configured to implement a radio frequency (RF) interface; a gateway coupled to the remote unit, the gateway communicatively coupled to an online provision service (OPS) certificate authority (CA); wherein the gateway is configured to generate an AuthToken unique to the remote unit, wherein the remote unit is configured to request a RU digital certificate and private key from an OPS CA based on the AuthToken.

A system is provided for configurably signing a secure data image that includes software code that interprets cryptographic atomic code. In the system, a code signing engine includes an interpreter that interprets atomic code signing operations presented in a recipe defined by a system administrator according to configuration parameter values supplied with the input image.

Configurable code signing system and method

A method is provided that permits user to submit a password to the private key that is to be used to decrypt files either at the time of user account setup or at the time of submitting the files. The password is stored securely in the system, permanently or temporarily, and is used later to decrypt the files right before the system is ready to process the files.

Secure deferred file decryption

In one embodiment, a method for secure virtualized wireless base station orchestration comprises: obtaining a node certificate and private key from a global CA defining a PKI signing certificate/private key; obtaining a sub CA certificate/private key from either an edge cloud node cluster or the global CA, using a PKI request signed using the PKI signing certificate/private key; establishing an orchestration access IPsec tunnel to a cloud comprising edge cloud orchestration functions; utilizing the orchestration functions to deploy on the node virtualized entities comprising VNFs of a wireless base station; obtaining at least one VNF certificate and private key for the VNFs from the global CA using a PKI request signed using the global certificate/private key; utilizing the VNF certificate/private key, establishing IPsec tunnels between the VNFs and a wireless network services operator network and/or to an OAM secure gateway for a DMS.

A method is provided for securely providing data for use in a consumer electronics device having a processor performing instructions defined in a software image. The method includes receiving the data encrypted according to a global key, further encrypting the data according to a device-unique hardware key, storing the further encrypted data in a secure memory of the consumer electronics device, providing the global key to a whitebox encoder for encoding according to a base key to generate a whitebox encoded global key, and transmitting the software image to the consumer electronics device for storage in an operating memory of the consumer electronics device, the software image having a whitebox decoder utility corresponding to the whitebox encoder and the whitebox encoded global key.

Method and apparatus for protecting confidential data in an open software stack

A method for signing data such as software images is provided that uses modules executable by a generic client to sign hashes of the software images rather than the images themselves. The method avoids both the requirement for new or updated client software and the uploading of full software images to the signing system. This approach uses a generic client that requests and downloads processing modules from the signing system to perform the pre-processing operations in signing software images, as well as optionally for post-processing operations.

Generic code signing client with downloadable modules

A system is provided for distribution of device key sets over a network in a protected software environment (PSE). In the system, a client device includes a connection interface for receiving a crypto hardware (CH) token belonging to a user, untrusted software, a quoting enclave, and a PSE for generating a provisioning request for a device key set. An attestation proxy server (APS) receives the provisioning message using a first network connection, and transmits the provisioning message to an online provisioning server (OPS) using a second network connection. The OPS constructs a provisioning response and an encrypted device key set, and delivers the provisioning response to the untrusted software using the first and second network connections. The PSE decrypts the encrypted device key set to obtain the device key set, re-encrypts the device key set with a local chip-specific key, and stores the re-encrypted device key set.
