Which of the cryptographic algorithms listed below is the least vulnerable to attacks?

Weakness ID: 327 Show Structure: Simple
The use of a broken or risky cryptographic algorithm is an unnecessary risk that may result in the exposure of sensitive information.
The use of a non-standard algorithm is dangerous because a determined attacker may be able to break the algorithm and compromise whatever data has been protected. Well-known techniques may exist to break the algorithm.
Cryptographic algorithms are the methods by which data is scrambled. There are a small number of well-understood and heavily studied algorithms that should be used by most applications. It is quite difficult to produce a secure algorithm, and even high profile algorithms by accomplished cryptographic experts have been broken. Since the state of cryptography advances so rapidly, it is common for an algorithm to be considered "unsafe" even if it was once thought to be strong. This can happen when new attacks against the algorithm are discovered, or if computing power increases so much that the cryptographic algorithm no longer provides the amount of protection that was originally thought.
Languages Class: Not Language-Specific (Undetermined Prevalence) Technologies Class: Not Technology-Specific (Undetermined Prevalence)
Example 1 These code examples use the Data Encryption Standard (DES). (bad code) Example Language: C (bad code) Example Language: Java Cipher des=Cipher.getInstance("DES..."); (bad code) Example Language: PHP function encryptPassword($password){ $iv_size = mcrypt_get_iv_size(MCRYPT_DES, MCRYPT_MODE_ECB); } Once considered a strong algorithm, DES now regarded as insufficient for many applications. It has been replaced by Advanced Encryption Standard (AES). Example 2 In 2022, the OT:ICEFALL study examined products by 10 different Operational Technology (OT) vendors. The researchers reported 56 vulnerabilities and said that the products were "insecure by design" [REF-1283]. If exploited, these vulnerabilities often allowed adversaries to change how the products operated, ranging from denial of service to changing the code that the products executed. Since these products were often used in industries such as power, electrical, water, and others, there could even be safety implications. At least one OT product used weak hashes.
Maintenance Since CWE 4.4, various cryptography-related entries, including CWE-327 and CWE-1240, have been slated for extensive research, analysis, and community consultation to define consistent terminology, improve relationships, and reduce overlap or duplication. As of CWE 4.6, this work is still ongoing.

Which of the following authentication protocols offer's countermeasures against replay attacks?Kerberos protocol prevention
The Kerberos authentication protocol includes some countermeasures. In the classic case of a replay attack, a message is captured by an adversary and then replayed at a later date in order to produce an effect.
What type of attacks do Kerberos authentication protect against select all that apply?What type of attacks do Kerberos authentication protect against? (Select all that apply.) Kerberos protects against replay attacks by timestamping the keys involved. Kerberos protects against man-in-the-middle attacks by performing mutual authentication between the principal and the Application Server (AS).
