Security of user data is for Apple one of the main priorities in the long term. You probably won't be surprised, therefore, that he works almost constantly to improve software and hardware security and deploys the results of his work on products every now and then. While they usually boast about most of them at least through a press release or something similar, they are silent about the new security improvement of the processors of older products. Only the updated support page revealed it. 

According to information from the official website Applu started Apple A12, A13, S4 and S5 chipsets use the second generation security coprocessor Secure Enclave, which can be simply described as a kind of separate vault for all security data, including encryption keys or data for Touch ID a Face IDIt is quite interesting, however, that the deployment of the second generation Secure Enclave apparently only the above-mentioned chips were affected, meaning that the iPhones 12 and 12 Pro equipped with A14 chipsets again only have the first generation, or a completely new solution (at least from a technical perspective). Applu). Another interesting thing is that the new Secure Enclave It only appears in products introduced in the fall of 2020, which in other words means that, for example, iPhones equipped with A12 chips have processors with the “old” version. The new Secure Enclave so it only beats in HomeOn the floor mini (thanks to S5), Apple Watch SE (thanks to the S5) and the 8th generation iPad (thanks to the A12). No other product was released with the aforementioned chip at the time of deployment. 

However, the ambiguities surrounding modified coprocessors still do not end here. The supporting document does not even state how the new product actually differs from the previous generation - i.e. whether it is, for example, safer, eliminates certain security risks, is more suitable for the products in which it is used, or anything similar. Apple so it keeps one of its biggest security weapons really well under wraps and, it seems, just won't let it go.
