What is SHA-3/384? 🔍

SHA-3/384 is a cryptographic hash function introduced by the National Institute of Standards and Technology (NIST) in 2015 as part of the SHA-3 family.

The SHA-3 family, developed using the Keccak algorithm, won the NIST hash function competition in 2012.

It is the successor to earlier algorithms like SHA-1 and SHA-2.

Here are the primary features of SHA-3/384:

  • 384-bit hash output: Offers an extremely low probability of hash collisions.
  • Sponge construction: Uses a unique absorption and squeezing process for secure data transformation.
  • Defined in FIPS PUB 202: Meets rigorous cryptographic standards.

This makes SHA-3/384 a go-to choice for applications requiring exceptional data security.

How Does SHA-3/384 Work? ⚙️

The SHA-3/384 algorithm operates on the principle of sponge construction, which processes data in two stages:

1. Absorption Phase

  • The input message is divided into blocks (832 bits each).
  • Each block is XORed with the internal state of the algorithm (the "sponge").
  • A Keccak-based permutation updates the state to ensure high entropy and randomness.

2. Squeezing Phase

  • The final hash is produced by extracting 384 bits from the sponge state.
  • The permutation ensures the output is unique and secure for any given input.

This two-phase approach ensures robust resistance to common cryptographic attacks, such as collision attacks and length extension attacks.

Strengths of SHA-3/384 🛡️

1. High Security Against Collisions

The 384-bit output makes it mathematically improbable for two different inputs to generate the same hash.

2. Immunity to Length Extension Attacks

Unlike SHA-2, SHA-3/384 is not susceptible to attackers appending data to an input to forge a valid hash.

3. Adaptability

SHA-3/384 works seamlessly in both hardware and software implementations, making it versatile for various applications.

4. Broad Applications

Used in digital signatures, message authentication, and data integrity verification, SHA-3/384 plays a crucial role in securing sensitive information.

Weaknesses of SHA-3/384 ❌

1. Computational Complexity

SHA-3/384 requires more processing time compared to SHA-256 or MD5, which might be a limitation for speed-critical applications.

2. Resource-Intensive

The sponge construction demands higher memory and computational resources, which might not suit low-powered devices.

Despite these drawbacks, the security benefits far outweigh the computational overhead for most use cases.

Applications of SHA-3/384 🔗

1. Digital Signatures

SHA-3/384 is used to generate a hash of the data being signed. This ensures that even the slightest change in the data will invalidate the signature.

2. Message Authentication Codes (MACs)

By combining a hash with a shared secret key, SHA-3/384 produces MACs to authenticate messages securely.

3. Data Integrity Verification

By comparing the hash of transmitted or stored data with the expected value, SHA-3/384 ensures no tampering or corruption has occurred.

4. SSL/TLS Protocols

SHA-3/384 is integrated into secure communication protocols to maintain confidentiality and integrity during data exchange.
