We'll identify common uses and we'll discuss secure boot and how it compares with measured boot. So let's get started. The underlying technology that enables an HSM was invented by Mohamed Atalla, an Egyptian engineer. He called his invention the Atalla box, and it could encrypt PIN and ATM messages and protect all flying devices with an unguessable PIN generating key. At the heart of his invention, lay the key block, which would allow for the secure interchange of symmetric keys or PINs between employees in the banking industry. The Atalla key block or AKB format, which enables this exchange, is the root of all cryptography used in the Payment Card Industry Data Security Standard, or PCI DSS, and the American National Standards Institute, or ANSI.
