Systems and methods for certificate chain validation of secure elements

A system for authenticating a device, comprising:

• a processor;
• and
• a memory storing a set of instructions which, when executed by the processor, cause the processor to:
• obtain a parent certificate including a parent public key, the parent public key comprising a public key modulus;
• associate a first identifier value with the parent public key;
• obtain a first hash value of the public key modulus of the parent public key;
• associate the first hash value with the parent public key;
• receive a child certificate from the device, the child certificate containing an identifier field, a data field, and a signature based on the identifier field and not based on the data field, the identifier field comprising a second identifier value, the second identifier value being different from the first identifier value, the data field comprising a second hash value, the second hash value of the data field of the child certificate being the same as the first hash value associated with the parent public key;
• determine that the second identifier value of the identifier field of the child certificate is not associated with the parent public key;
• determine that the second hash value of the data field of the child certificate is associated with the parent public key;
• identify the parent public key based on the second hash value;
• and
• validate the child certificate using the parent public key.
