Coset coding is a typical method of secure coding in physical layer security. This paper focuses on coset coding based on the random linear codes in binary symmetric channel. While analyzing system security, we derive the formula of eavesdropper's equivocation and proposed a novel code extending algorithm based on the optimization of minimum distance. On the basis of ensuring minimum distance of the code reaching the maximum, the algorithm searches the achievable extended column to ensure the equivocation of eavesdropper up to the most as well. The simulations show, compared with the best known code (BKC) and best equivocation code (BEC) of the same code length and rate, the proposed algorithm has better security and higher efficiency.
