NEW QUESTION # 85
(What is the relationship between Secure Sockets Layer (SSL) and Transport Layer Security (TLS)?)
Answer: D
Explanation:
TLS is the modern successor to SSL. SSL (notably SSL 2.0 and SSL 3.0) was an early protocol family for securing network communications, providing encryption, integrity, and endpoint authentication for applications like HTTPS. Over time, weaknesses were discovered in SSL's design and in the cryptographic mechanisms commonly used with it. TLS was introduced as an improved, standardized evolution (starting with TLS 1.0, based on SSL 3.0 but with important fixes), and later versions (TLS 1.2 and TLS 1.3) significantly strengthened security by removing weak ciphers, improving key exchange, and tightening handshake and record protections. In practice, when people say "SSL" today, they often mean "TLS," but true SSL is deprecated and should not be used. SSL is not a replacement of TLS, and the two are not identical in security-TLS versions incorporate substantial improvements and modern cryptographic best practices. SSL is also not limited to email; it was widely used for web traffic and other protocols. Therefore, the correct relationship is that TLS replaced SSL to provide improved security.
NEW QUESTION # 86
(What is the primary purpose of the Health Insurance Portability and Accountability Act (HIPAA) in relation to encryption?)
Answer: A
Explanation:
HIPAA is a U.S. regulation focused on protecting the privacy and security of protected health information (PHI). In relation to encryption, HIPAA's Security Rule requires covered entities and business associates to implement appropriate administrative, physical, and technical safeguards to ensure the confidentiality, integrity, and availability of electronic PHI. Encryption is widely recognized as a key technical safeguard for confidentiality-protecting PHI in transit (e.g., over networks) and at rest (e.g., on storage devices) by making data unreadable without the proper keys. HIPAA does not standardize encryption across all industries, nor does it prohibit electronic health records; it regulates how they must be protected. While HIPAA often uses the term "addressable" for encryption controls (meaning organizations must implement it if reasonable and appropriate, or document an equivalent alternative), the overarching purpose remains protection of patient information through secure measures, with encryption as a central mechanism. Therefore, the best answer is ensuring confidentiality of patient information through secure measures like encryption.
NEW QUESTION # 87
(What does nonrepudiation aim to achieve in the context of cryptography?)
Answer: B
Explanation:
Nonrepudiation aims to prevent a party from later denying having performed an action, such as sending a message, approving a transaction, or signing a document. In cryptographic systems, nonrepudiation is typically supported by digital signatures, audit logs, and trusted time-stamping: if a message is signed with a private key and verified with the corresponding public key (often bound to an identity via a certificate), the signer can be held accountable for that signed content. This creates evidence that can be used for dispute resolution, compliance, and legal or contractual enforcement. Nonrepudiation is distinct from confidentiality (keeping data secret) and from access control (preventing unauthorized use). While authentication (verifying identity) is related and often a prerequisite, the defining goal is accountability-ensuring that actions can be attributed to entities in a way that is difficult to dispute later. Effective nonrepudiation also depends on secure private key management, certificate validation, and procedures that show the key was under the signer's control at the time. Therefore, the correct answer is holding parties accountable for their actions and transactions.
NEW QUESTION # 88
(What is the length of the Initialization Vector (IV) in WEP?)
Answer: A
Explanation:
WEP (Wired Equivalent Privacy) uses the RC4 stream cipher and combines a per-packet Initialization Vector (IV) with a shared secret key to form the RC4 seed for that packet's keystream. The IV in WEP is 24 bits long and is transmitted in the clear as part of the 802.11 frame so the receiver can reconstruct the same per-packet RC4 key stream. The short IV space (2²# possible values) is a major design weakness: on a busy network, IVs repeat frequently, causing keystream reuse. Because RC4 is a stream cipher, keystream reuse enables attackers to derive relationships between plaintexts and recover keys with statistical attacks (notably the Fluhrer, Mantin, and Shamir (FMS) family of attacks and related improvements). WEP also uses a CRC-32 integrity check (ICV) that is not cryptographically strong and is vulnerable to modification attacks. The 24-bit IV length is therefore a key reason WEP is considered insecure and has been replaced by WPA/WPA2 mechanisms that use stronger key mixing, larger nonces/IVs, and robust integrity protection.
NEW QUESTION # 89
(Which attack may take the longest amount of time to achieve success?)
Answer: D
Explanation:
A brute-force attack exhaustively tries every possible key or password candidate until the correct one is found. Because it explores the full search space (or a very large portion of it), brute force is often the slowest method, especially when strong keys, long passwords, rate limits, and slow password hashing (bcrypt/Argon2) are used. By contrast, a dictionary attack reduces work by trying only common or likely passwords, often succeeding quickly against weak human-chosen secrets. Rainbow table attacks shift work into precomputation; once a table exists, lookup can be faster than brute-force-though salt and modern hashing defeat them. Birthday attacks are about finding collisions, not necessarily recovering a specific secret, and their expected work is about 2
