No.

Bitcoins security strength is at 128 bit.
With ECDSA on secp256k1 and a key size of 256 bit, the strength is at 128 bit.

2⁵¹² bit is an absurdly large number and completely off. But i guess you meant 512 bit.
ECDSA's security is dependend on the key size. With a key length of 2ⁿ bit, the bit strength (security) is at 2^n-1 bit.
