The cornucopia of bugs placed in Russian diplomatic facilities proved to be very useful in identifying particular individuals responsible for ordering certain covert operations. Computers generate random number for everything from cryptography to video games and gambling. Mobile security, or mobile device security, is the protection of smartphones, tablets, and laptops from threats associated with wireless computing. secp256k1 refers to the parameters of the elliptic curve used in Bitcoin's public-key cryptography, and is defined in Standards for Efficient Cryptography (SEC) which significantly reduces the possibility that the curve's creator inserted any sort of backdoor into the curve.

Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields.ECC allows smaller keys compared to non-EC cryptography (based on plain Galois fields) to provide equivalent security.. Elliptic curves are applicable for key agreement, digital signatures, pseudo-random generators and other tasks.
