This method can provide shared access control on key material and other secrets that must be strongly protected. This note defines a threshold secret sharing method based on polynomial interpolation in GF(256) and a format for the storage and transmission of shares. It also provides usage guidance, describes how to test an implementation, and supplies test cases.}, }
