Motivation There is currently no any isomorphic ECC library which provides ECDSA, ECDH and ECIES for both Node.js and Browser and uses the fastest implementation available (e.g. secp256k1-node is much faster than other libraries but can be used only on Node.js). Webthe impact of public-key cryptography, we use Elliptic-curve Diffie-Hellman (ECDH) for establishing the 128-bit shared symmetric key for MAP. For instance, when using the secp256r1 curve, executing ECDH key exchange on the dedicated peripheral before starting the MAP protocol adds 1457 µJto the security energy budget needed. chillies museum in dr prtersbetb fl
