WebUsing Elliptic Curve Diffie-Hellman. When using a curve from FIPS 186-4, a base point order and key size of at least 224 bits for correctly implemented ECDH provides 112 bits of effective security strength. Security of a curve selected from another source cannot be assumed to have the same security using base point order and key size alone. The protocol is considered secure against eavesdroppers if G and g are chosen properly. In particular, the order of the group G must be large, particularly if the same group is used for large amounts of traffic. The eavesdropper has to solve the Diffie–Hellman problem to obtain g . This is currently considered difficult for groups whose order is large enough. An efficient algorithm to solve the discrete logarithm problem would make it easy to compute a or b and solve the Diffie–… tide times in exmouth
