SHA-384 (Secure Hash Algorithm 384) - History, Features, Security, and Applications

• History of SHA-384

  SHA-384 is a hash algorithm from the SHA-2 (Secure Hash Algorithm 2) family, published by the National Institute of Standards and Technology (NIST) in 2001. SHA-384 was developed as a variant of SHA-256, offering a 384-bit output for enhanced security. SHA-384 was created to address the security vulnerabilities of SHA-1 and is widely used in various security systems today.

  
  

• Key Features of SHA-384

  SHA-384 has a fixed 384-bit hash output length, providing strong security and ensuring data integrity.

  Key features of SHA-384 are:

  - Fixed Output Length: Regardless of the input data size, SHA-384 always produces a 384-bit (48-byte) hash value.

  - Strong Collision Resistance: SHA-384 provides excellent resistance to collision attacks, meaning the likelihood of two different inputs producing the same hash value is extremely low.

  - Fast Computation Speed: SHA-384 can generate hash values at high speed, ensuring efficient computations.

  - Irreversibility: It is computationally infeasible to reverse-engineer the original input data from the hash value.

  
  

• Security of SHA-384

  SHA-384 was designed to address the security issues of SHA-1, and no significant vulnerabilities have been discovered so far. It offers strong security features, including resistance to collisions and brute-force attacks.

  Security Evaluation of SHA-384:

  - Collision Resistance: SHA-384 offers excellent collision resistance, making it a highly secure choice.

  - Brute Force Attack Resistance: The 384-bit output size makes brute-force attacks practically impossible.

  - Stability of the SHA-2 Family: Since SHA-384 is part of the SHA-2 family, it is considered a secure and reliable hash function.

  
  

• Key Applications of SHA-384

  SHA-384 is widely used in environments where strong security is required. It plays a vital role in encryption, data protection, and many other security-critical applications.

  Key Applications of SHA-384:

  - Digital Signatures and Certificates: SHA-384 is used to verify data integrity, playing a key role in digital signatures and certificates.
