An Apple Support document has now revealed that Apple made a rather unusual change to the production of its A12 and S5 processors last fall.<\/strong><\/p>\n\n\n\n

According to the company, Apple updated the Secure Enclave in the A12 and S5 processors to a second-generation version of the memory component in fall 2020.<\/p>\n\n\n\n

What is the Secure Enclave?<\/h3>\n\n\n\n\n\n\n\n

For those unfamiliar with the subject, the Secure Enclave is a secure coprocessor that is included in almost every Apple device and provides an additional layer of security. All data stored on iPhone, iPad, Mac, Apple Watch and other Apple devices is encrypted with random private keys that only the Secure Enclave can access. These keys are unique and remain stored locally on the device. This means that there is no synchronization with iCloud. But the chip is not only responsible for encrypting the files, it is also responsible for storing the keys that manage sensitive data such as passwords, the credit card used by Apple Pay and even the biometric identification used to activate Touch ID and Face ID. Although the chip is permanently installed in the device and is a hardware component, it is completely separated from the rest of the system. This means that it works independently.<\/p>\n\n\n\n

Apple Support Document Causes Confusion<\/h3>\n\n\n\n

Apple's specific adjustment here refers to the "Secure Storage Component" in which this data is stored within Apple's Secure Enclave. The change in question was discovered by Andrew Pantyukhin and posted on Twitter divided<\/a>. The cited support document appears to have been last updated in February. explained<\/a> Apple:<\/p>\n\n\n\n

Note: A12, A13, S4 and S5 products released in fall 2020 will have a 2nd generation Secure Storage Component while earlier products based on these SoCs will use a 1st generation Secure Storage Component.<\/p><\/blockquote>\n\n\n\n

This means that the following products, which are not equipped with the latest A14 and S6 processors, now have the second generation of this component:<\/p>\n\n\n\n
