cryptographic collision

[krɪp.təˈɡræf.ɪk kəˈlɪʒ.ən]
nounpl: cryptographic collisions
colisão criptográfica
1. A situation in cryptography where two different inputs produce the same output hash value, compromising the security of hash functions
A cryptographic collision in the MD5 algorithm was discovered, rendering it unsuitable for further use in security applications.
Uma colisão criptográfica no algoritmo MD5 foi descoberta, tornando-o inadequado para uso contínuo em aplicações de segurança.
2. An unintended event where distinct data items hash to the same cryptographic value, breaking the one-way property of the hash function
The researchers demonstrated a practical cryptographic collision attack against the SHA-1 hashing function.
Os pesquisadores demonstraram um ataque prático de colisão criptográfica contra a função de hash SHA-1.
This is a specialized technical term used primarily in cybersecurity, computer science, and cryptography communities in both Brazil and the USA. It gained significant cultural prominence following the discovery of practical collision attacks against widely-used algorithms like MD5 and SHA-1 in the 2000s, which shaped discussions about digital security standards and data protection regulations in both countries.
