Three of the 64 questions in this pack

Question 1

Sheryl is explaining PKI to a group of non-technical executives. She first wants to identify the specific components of PKI. Which one of the following is a component of the PKI?

  1. CA
  2. TGT
  3. OCSP
  4. TGS
Show answer and explanation

Correct answer: A. CA

A Certificate Authority (CA) is a core component of Public Key Infrastructure responsible for issuing, managing, and revoking digital certificates. The CA validates the identity of entities and signs certificates with its private key, establishing the trust foundation of the PKI system.

Why the other options are wrong

  • B. TGT (Ticket Granting Ticket) is a component of Kerberos authentication, not PKI.
  • C. OCSP (Online Certificate Status Protocol) is a protocol used within PKI to check certificate revocation status, not a primary structural component of PKI itself.
  • D. TGS (Ticket Granting Service) is part of the Kerberos protocol, not a PKI component.

Question 2

You are studying classic ciphers. You have been examining the difference between single substitution and multi-substitution. Which one of the following is an example of a multi-alphabet cipher?

  1. Atbash
  2. Vigenère
  3. Caesar
  4. Rot13
Show answer and explanation

Correct answer: B. Vigenère

The Vigenère cipher is a multi-alphabet substitution cipher that uses a repeating key to encrypt plaintext by shifting each letter by a different amount depending on the corresponding key letter position. This polyalphabetic approach makes it significantly more resistant to frequency analysis than single-alphabet substitution ciphers.

Why the other options are wrong

  • A. Atbash is a single-alphabet substitution cipher that maps each letter to its reverse in the alphabet.
  • C. Caesar cipher is a single-alphabet substitution cipher that shifts every letter by a fixed number of positions.
  • D. Rot13 is a single-alphabet substitution cipher that shifts every letter by exactly 13 positions.

Question 3

3DES can best be classified as which one of the following?

  1. Hashing algorithm
  2. Digital signature
  3. Symmetric algorithm
  4. Asymmetric algorithm
Show answer and explanation

Correct answer: C. Symmetric algorithm

3DES (Triple DES) is a symmetric encryption algorithm that applies the DES cipher three times to each data block. It uses the same key (or keys derived from the same key material) for both encryption and decryption, which is the defining characteristic of symmetric algorithms. 3DES was widely used to strengthen DES before AES became the standard.

Why the other options are wrong

  • A. Hashing algorithms produce fixed-size digests and are not used for encryption; 3DES is an encryption cipher.
  • B. Digital signatures are cryptographic mechanisms for authentication and non-repudiation; 3DES is an encryption algorithm.
  • D. Asymmetric algorithms use different keys for encryption and decryption (public and private keys); 3DES uses the same key for both operations.

What makes the ECES hard

ECES is a small exam with a narrow subject: 50 questions in two hours on nothing but cryptography. That makes it deceptively hard, because there is nowhere to hide. Every question is about an algorithm, a mode, a key length, a protocol or an attack, and the v3 update brought in post-quantum cryptography and quantum computing threats, which older material does not cover at all.

The blueprint follows the ECES course: classical ciphers and foundations, symmetric cryptography and hashes including AES, block cipher modes and SHA family hashing, number theory and asymmetric cryptography covering Diffie-Hellman, RSA and elliptic curves, applied cryptography including PKI, TLS, IPsec and disk encryption, cryptanalysis, and the newer quantum and post-quantum module.

The passing score is 70%, and with only 50 questions covering six topic areas, a weak spot in any one of them costs several marks at once.

About the exam

212-81 v3 (Certified Encryption Specialist) earns the EC-Council ECES certification. It covers the history and foundations of cryptography, symmetric ciphers and hashing, number theory and asymmetric cryptography, applied cryptography including PKI, TLS, VPN and disk encryption, cryptanalysis, and quantum and post-quantum cryptography. Eligibility is official EC-Council training, or one year of information security experience with a US$100 application fee.
