Minimal binary linear codes are a special class of binary codes with important applications in secret sharing and secure two-party computation. These codes are characterized by the property that none of the nonzero codewords is covered by any other codeword. Denoting byandthe minimum and maximum weights of the codewords, respectively, such codes are relatively easy to design when the ratiois larger than 1/2 (known as the Ashikhmin-Barg bound). On the other hand, a few known classes of minimal codes violate this bound, hence having the property. In this article, we provide severalexplicitclasses of minimal binary linear codes that violate the Ashikhmin-Barg bound while achieving a great variety of the ratio. Our first generic method employs suitable characteristic functions with relatively low weights within the range [n+ 1,2n− 2]. The second approach specifies characteristic functions with weights in [2n− 2+ 1,2n− 2+ 2n− 3− 1], whose supports contain a skewed (removing one element) affine subspace of dimensionn− 2. Finally, we also characterize an infinite family of minimal codes based on the class of so-called root Boolean functions of weight 2n− 1− (n− 1), useful in specific hardware testing applications. Consequently, many infinite classes of minimal codes crossing the Ashikhmin-Barg bound are derived from an ample range of characteristic functions. In certain cases, we completely specify the weight distributions of the resulting codes.
