WebDigital signatures following the methodology of \Fiat-Shamir with Aborts", proposed by Lyubashevsky, are capable of achieving the ... and the NTRU signature scheme [24]. They use the \trapdoor approach". Namely, they let the public veri cation key and the secret signing key (the trapdoor) be a \bad" basis and a \good" basis of a lattice ... WebA digital signature consists of three efficient algorithms: KeyGen : It takes the security parameter as input, and output a pair of key , where pk is called the public key (or verification key) and sk is called the secret key (or signing key). This algorithm is called the key generation algorithm.
