Secure point of sale device with dual security processors
The patent US12067546B2 describes a sophisticated point of sale (POS) device designed to enhance transaction security through a dual-casing architecture. The device comprises a first casing that houses an applications processor and a first security processor, which is equipped with a tamper detection circuit. This first casing is connected to a second casing that contains a second security processor, also featuring a tamper detection circuit. A secure connection is established between the two security processors, allowing them to communicate securely. The system utilizes a unique pre-shared key generated through a key exchange algorithm, facilitating secure transaction processing by receiving and authorizing information from both casings.
Additionally, the patent outlines various technical features that enhance the device's functionality. It includes provisions for a touch display that operates in both secure and unsecure modes, and it supports connections via universal serial bus (USB) or wired connections. The device employs an authenticated and confidential channel establishment (ACCE) protocol, specifically a transport layer security (TLS) protocol, to ensure secure communications. The applications processor is programmed to handle certificate signing requests, translating them into hypertext transfer protocol (HTTP) requests for interaction with a certificate authority. This innovative design aims to improve the security and efficiency of transaction processing in POS systems, making it a significant advancement in the field.
