CompTIA Security+ SY0-701 (V7) Practice Question

A security architect is designing a secure communication protocol for a new IoT deployment. A primary requirement is to enable two devices to securely generate a shared secret key for encrypting their traffic, even if their initial communication is monitored. The solution must also be highly efficient to accommodate the low-power nature of the devices. Which of the following cryptographic mechanisms is BEST suited for this purpose?

  • Secure Hash Algorithm 256 (SHA-256)

  • Rivest-Shamir-Adleman (RSA)

  • Advanced Encryption Standard (AES)

  • Elliptic Curve Diffie-Hellman (ECDH)
