【TrustZone 杜絕非法訪問+安全連接 AWS】
物聯網 (IoT) 設備內嵌的智慧功能越來越多,在設計之初就須將安全性考慮進去;然而,微控制器 (MCU) 是否有能力兼顧資安、實現可信賴運算 (Trusted Computing, TC)?
安謀 (Arm) 的「PSA 平台安全架構」為網路安全性原則實施提供一個通用框架,讓安全性成為 IoT 的核心設計要求;其中,TrustZone 是 PSA 的系統級安全擴展方案,已被業內廣泛應用,可在「片上」實現靈活的硬體和軟體安全隔離 (參閱:《5G 智能邊緣肩負重任,嵌入式系統的資安怎解?》http://compotechasia.com/a/feature/2020/0710/45216.html 一文)。
集成 TrustZone IP 模組得以實現可信賴運算原理,用於驗證聯網設備的身份,阻止企圖破壞設備或軟體的攻擊和入侵,並為敏感代碼創建受保護的安全執行環境,保護加密演算法和金鑰儲存的安全。擁有 PSA 認證,可對安全性進行獨立驗證,將私鑰和安全規範資訊儲存在安全區域,杜絕非法訪問。
以意法半導體 (ST) 首款採用 Arm Cortex-M33 的 STM32L5 為例,使用者可在 TrustZone 保護區內更自由地添加或移除任一 I/O、外設、快閃記憶體或 SRAM 儲存區,將敏感任務完全隔離。ST 還優化了 TrustZone,提供加強版安全功能,包括:靈活的軟體隔離、安全啟動、金鑰儲存和硬體加密加速器,支援安全啟動、片上 SRAM 和快閃記憶體專用讀防寫及保護外部代碼或資料的加密加速技術。好處是:在軟體耗盡外部記憶體時可提高取指效率。
當然,低功耗仍是必要條件,以供鈕扣電池或能量收集器長久續航——自我調整電壓調節、即時加速、功率門控和先前經市場檢驗的多種低功耗模式,讓關機模式功耗低至 33nA;另內建高效開關式降壓穩壓器,可在 VDD 電壓足夠高時改進低功耗能效,並允許運行狀態上、下電。STM32L5 不僅擁有多種數位類比外設及 CAN FD、USB Type-C 和 USB-PD 通訊介面,還備有創新「物聯網雲連接器」,可使用 Wi-Fi 互聯網通訊配置安全連接 Amazon Cloud!

<Talk>Title: Fog Computing Alliance-Special Seminar: Blockchain based Off-Chain Trusted Compute by iExec
#Time: October 18th, Friday, 2019 / 10-11am
#Venue: Room 108, 1F, Engineering Building IV, NCTU
交通大學工程四館一樓108室
#Abstract:
EEA (Enterprise Ethereum Alliance) Off-Chain Trusted Compute Specification V1.1 was released during Devcon 5 (8th October 2019, Osaka). This specification defines how BlockChain can seamlessly work with TEE(Trusted Execution Environment) to:
- Provide E2E privacy preserving for Blockchain based computing.
- Provide trusted execution verification for Blockchain based computing.
As one of the main editors of EEA Off-Chain Trusted Compute Specification V0.5, V1.0 and V1.1, our guests will present the latest status of the specification, the involved latest Hyperledger project -- Avalon (officially announced on 3rd October 2019) as well as the exciting EEA use cases that will be significantly impacting the Ethereum Enterprise Community -- EEA Trusted Token (officially announced on 9th October 2019, Osaka), and as the principal architect of this project, they will also present the architecture and the workflow of EEA Trusted Token.
