C839v5 / D334 DRO2 Chapter 4 – Asymmetric Encryption, RSA, ECC & Homomorphic Crypto |Verified Questions with A+ Graded Answers Public key encryption is an asymmetric key method that uses a public key (which can be distributed) and a private key (which should be kept private). True False _____ cryptography is better suited for real-time communications implementations than ______ cryptography. Conventional, Light-weight Symmetric, Asymmetric Asymmetric, symmetric Asymmetric, Public-key Given the list below, the most common practical uses for public-key cryptography include_______. Select two. Hashing data Encrypting of data within a tunnel Identity checking Key protection RSA derives its security from the computational difficulty of factoring large integers that are the product of two large ______ numbers. Rational Odd Prime Even Deriving key pairs in public-key cryptography involves multiplying two large prime numbers. The difficulty of, and time required to determine the prime numbers used in that process, forms the basis of public-key cryptography security. The process used to determine the original primes is known as______. Factoring Forward engineering Quantum binary Hypothesis ________ is an alternative to PKI (Public Key Infrastructure), and involves generating the encryption key from a piece of the identity of the recipient. ECC PHOTON IBE IKE The _______ cryptosystem, is a homomorphic encryption scheme which allows two types of computation: addition of two ciphertexts, and multiplication of a ciphertext by a plaintext number ECC MD5 Paillier RC5 Select the options from the list below that support some form of homomorphic encryption. Select all that apply. SHA-1 SHA-256 RSA Paillier Use of RSA would be ideal for implementation in embedded systems with limited capacity for heavy power and processing overhead. True False In comparing ECC and RSA, which would be better suited for use with embedded systems? RSA, as embedded systems which would struggle to cope with the processing requirements of ECC ECC, as embedded systems which would struggle to cope with the processing requirements of RSA ______ is a public key encryption method that is an extension of El Gamal but adds a one-way hashing method which protects against an adaptive chosen ciphertext attack. Cramer-Shoup SHA-Gamal AES-CBC AES With Bitcoins, the _____ key defines our identity and we use it to sign for transactions, and prove our identity to others with the ______ key when making use of ECC. local, ephemeral ephemeral, local private, public public, private El Gamal is a symmetric key cryptography method that is used in both encryption and digital signing. It is used in many applications and uses discrete logarithms. True False Cramer-Shoup is a public key encryption method that is an extension of El Gamal but adds a _______ which protects against an adaptive chosen ciphertext attack. one-way hashing method initialization vec
