ECDSA (Elliptic Curve Digital Signature Algorithm) is more secure with shorter keys compared to RSA, and it also has faster verification speeds, making it widely applicable. Since the ECDSA algorithm can only perform signing and cannot handle encryption and decryption, the ECIES (Elliptic Curve Integrated Encryption Scheme) was developed. The ECIES uses the ECDH algorithm … Read more
1. Definition of Asymmetric Encryption Algorithms An asymmetric encryption algorithm is a type of encryption technology that uses a pair of keys for encryption and decryption. Unlike symmetric encryption, asymmetric encryption uses two keys: a public key for encrypting data and a private key for decrypting it. Only the recipient who possesses the private key … Read more

This article is a featured article from the Kanxue Forum. Author ID on Kanxue Forum: LunaYoung Talosec Core Team: Wang An, Yang Xiaoya We conducted a security assessment of an open-source hardware wallet using side-channel analysis. This wallet’s chip is based on the ARM-Cortex-M4 core, which uses the Elliptic Curve Digital Signature Algorithm (ECDSA) for … Read more
