Abstract
According to various embodiments, a method for code-based generation of a key pair for asymmetric cryptography is described including generating a private key defining a linear code, determining a parity check or generator matrix for the linear code, blinding a sub-matrix of the parity check or generator matrix, generating a blinded inverse matrix by inverting the blinded sub-matrix or by inverting a quadratic matrix contained in the blinded sub-matrix, de-blinding the blinded inverse matrix to generate an inverse matrix and generating a public key for the private key using the inverse matrix.
