WebSee “Security.SE: What asymetric scheme provides the shortest signature, while being secure?”, “Security.SE: How to encrypt a short string to a short ciphertext using an asymmetric encryption?”, and “Crypto.SE: Short length asymmetric encryption?” for details. ECDSA should give you a 320-bit signature with approximately 80-bit security. WebKey and signature-size. As with elliptic-curve cryptography in general, the bit size of the private key believed to be needed for ECDSA is about twice the size of the security level, in bits. For example, at a security level of 80 bits—meaning an attacker requires a maximum of about operations to find the private key—the size of an ECDSA private key would be 160 bits.
WebJun 16, 2024 · The receiver takes as input the signature and with the public key ( sent with the message) verify it using verification algorithm and produce the hash as output. According to what I understand, the receiver performs the revere action, which is equivalent to encryption /decryption, using private/public key instead of the same private key.
