Domain parameter generation: The domain parametric quantity for ECDSA consist of a appropriately chosen elliptic curve E defined over a finite field Zp of characteristic q, and a base point R [member of] Ep(x, y) with order n.
ECDSA signature generation: To sign a message m, an entity A with domain parametric quantity (q, Ep(x, y), R, n) and associated key pair (i, K) does the following:
ECDSA signature verification: To assert A's signature (r, s) on m, B obtains an authentic copy of A's domain parameter ( q, Ep(x, y), R, n) and associated public key K.
Although ECDSA signature has been accepted as standard signature algorithm in elliptic curves, parameter U [member of] [Z.
With ECDH and ECDSA built in, this device is ideal for the rapidly growing IoT market by easily providing confidentiality, data integrity and authentication in systems with MCU or MPUs running encryption/ decryption algorithms (such as AES) in software.
