This document summarizes a research paper on using randomized chained linear codes for digital signatures. The summary is:
1) Randomized chained linear codes are proposed to address attacks on previous signature schemes that used regular chained codes. Random vectors are concatenated to the generator matrix of a chained code to create randomized chained codes.
2) A digital signature scheme is presented that uses randomized chained codes. The private key consists of the generator matrix and randomization matrices. The public key is the randomized parity check matrix. Signatures are created using the chain code decoding algorithm.
3) Security analysis shows the scheme is secure if the code length is over 1350 bits, preventing an attacker from determining the private key from the public information
