As an electronic analogue of a written signature, a digital signature provides assurance that: the claimed signatory signed the information, and the information was not modified after signature generation. Federal Information Processing Standard (FIPS) 186-4, Digital Signature Standard (DSS), specifies three NIST-approved digital signature algorithms: DSA, RSA, and ECDSA. All three are used to generate and verify digital signatures, in conjunction with an approved hash function specified in FIPS 180-4, Secure Hash Standard or FIPS 202, SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions. February 3, 2023 NIST published Federal Information Processing Standard (FIPS) 186-5, Digital Signature Standard (DSS), along with NIST Special Publication (SP) 800-186, Recommendations for Discrete Logarithm-based Cryptography: Elliptic Curve Domain Parameters.

Permute Last Layer (PLL)
There are a total of 21 algorithms for this stage. They are distinguished by letter names, often based on what they look like with arrows representing what pieces are swapped around (e.g., A-perm, F-perm, T-perm, etc.).
Hashed value of original message is encrypted with sender's secret key to generate the digital signature. It is generated by CA (Certifying Authority) that involves four steps: Key Generation, Registration, Verification, Creation. Authenticity of Sender, integrity of the document and non-repudiation.
