WebThe paper is organized as follows. In the next section, we briefly introduce the RSA-based blind signature form, ECC-based blind signature protocol, and signcryption manner, respectively. In Section 3, we propose an original essay to construct a signcryption-combined scheme for blind digital signatures. WebExamples are scalar blinding and point blinding, which randomize the point representation and the key bits’ evaluation [4]. ... In many ECC applications that compute kP, k is a secret key. This implies that this operation has to be protected against all attacks. In particular, many side-channel attacks [3,9] and countermeasures [4]
