NIST security categories (post quantum) Here (https://www.safecrypto.eu/pqclounge/round-2-candidates/) are collected all the proposals which passed the first round of NIST Post-Quantum Cryptography Standardisation process. What does the abbreviations in "NIST security categories" column mean? Where can I find a formal definition of them?
A copy and paste from page 16 of NIST document Submission Requirements and Evaluation Criteria
for the Post-Quantum Cryptography Standardization Process;


Any attack that breaks the relevant security definition must require computational
resources comparable to or greater than those required for key search on a block
cipher with a 128-bit key (e.g. AES128)
Any attack that breaks the relevant security definition must require computational
resources comparable to or greater than those required for collision search on a
256-bit hash function (e.g. SHA256/ SHA3-256)
Any attack that breaks the relevant security definition must require computational
resources comparable to or greater than those required for key search on a block
cipher with a 192-bit key (e.g. AES192)
Any attack that breaks the relevant security definition must require computational
resources comparable to or greater than those required for collision search on a
384-bit hash function (e.g. SHA384/ SHA3-384)
Any attack that breaks the relevant security definition must require computational
resources comparable to or greater than those required for key search on a block
cipher with a 256-bit key (e.g. AES 256)
