Cоnsider the server design shоwn in the figure. The server аccepts lаrge input dаta frоm clients, processes it using a master process and multiple worker processes, and returns a 64-bit output. The master and workers communicate through inter-process synchronization and shared memory. The server also includes trusted-computing support and optional mechanisms such as caching and access control. (a) Concurrent processing and shared memory [5 pts] The shared memory stores both input data and metadata, such as type, size, task_id, status, and result. Give one concrete example of how a race condition may occur between the master and worker processes. [2 pts] Explain how an inter-process mutex lock can be used to prevent the race condition. Be specific about what operations should be protected. [3 pts] (b) Trusted computing and attestation [5 pts] Assume the server has three software layers: BIOS/firmware, kernel, and server application. A hardware root of trust provides a private signing key K and a secure hash function H. Why should the integrity measurement be signed before being sent to a client? [2 pts] Describe how to generate a signed integrity proof using a hash chain over the three software layers. [3 pts] (c) Additional improvement [4 pts] Propose one additional mechanism, such as caching, authentication, access control, input validation, rate limiting, sandboxing, or logging, to improve the server. Describe the mechanism. [2 pts] Explain why it improves efficiency, reliability, or security. [2 pts]
