An Internet-connected device, such as a car, refrigerator, or even a laptop can use a second device, such as a cell phone, to support cryptographic operations and communication with token service providers or other processing services requiring pre-provisioned capabilities that may include cryptographic secrets. By removing the need to store personally sensitive data in 'Internet of Things' (IoT) devices, a user's personal information and other sensitive financial information may be contained to a relatively small number of devices. This may help prevent theft of goods or services by IoT devices that are not always under the close control of the user.

In certificate chain validation, a parent certificate is used to validate a child certificate. The child certificate can indicate which parent certificate can be used to validate it. In some situations, a child certificate may not contain a certificate authority identifier that can be used to identify the parent certificate. Instead, the child certificate can contain a hash value of a modulus of the parent public key that can be used to identify the parent certificate. The hash value of the modulus of the parent public key can be associated with the parent public key. As such, the parent public key used in certificate chain validation of the child certificate can be identified using the hash value of the modulus of the parent public key.
