Exam CAS-004 topic 1 question 173 discussion

Embedded cryptoprocessor (option B): An embedded cryptoprocessor is a specialized chip that is designed to perform cryptographic operations, such as encrypting and decrypting data, generating and verifying digital signatures, and generating and storing cryptographic keys. By installing an HSM with an embedded cryptoprocessor in the mobile device, the organization can ensure that sensitive data is processed and stored in a secure manner. Hardware-backed public key storage (option C): A hardware-backed keystore is a secure storage area that is physically isolated from the rest of the device and is designed to store cryptographic keys. By using an HSM with hardware-backed public key storage, the organization can ensure that public keys are stored in a secure and tamper-resistant manner, which is important for ensuring the security of digital certificates and other sensitive data.

Not only another site has the answer BC as correct, also it clearly stated the chip uses HSM not TPM. For more details i used the linked below to tell the difference and also explain why BC is correct https://security.stackexchange.com/questions/88744/what-are-the-differences-between-tpm-and-hsm

B. Embedded cryptoprocessor C. Hardware-backed public key storage Explanation: B. Embedded cryptoprocessor: A cryptoprocessor is a specialized processor designed for performing cryptographic operations securely. By embedding it in a microSD HSM, the device can securely perform encryption, decryption, and key generation without exposing sensitive data to the rest of the mobile device. This enhances the security of corporate resources accessed remotely, which aligns with the organization's goal of protecting sensitive data. C. Hardware-backed public key storage: Storing public keys and private keys in hardware (such as an HSM) ensures that the keys are securely stored and protected from being extracted or tampered with. This is crucial for the secure access to corporate resources, as it allows the mobile device to authenticate and establish secure communications using cryptographic techniques, but without risking key exposure to malware or unauthorized access.

Source: Verifying each answer against Chat GPT, my experience, other test banks, a written book, and weighing in the discussion from all users to create a 100% accurate guide for myself before I take the exam. (It isn't easy because of the time needed, but it is doing my diligence)

The correct answers are: Embedded cryptoprocessor, Decentralized key management

BC is the correct answer

B and C are the most important features of an HSM
