Abstract
A firmware update method includes: using, a first deterministic random bit generator to obtain a first key and a first verification code by a first computing device; using the first key to encrypt first firmware update data and the first verification code to output first encrypted data by the first computing device; receiving second encrypted data by a second computing device; using a second deterministic random bit generator to obtain a second key and a second verification code by the second computing device; using the second key to decrypt the second encrypted data to obtain a third verification code and second firmware update data by the second computing device; and updating a firmware of the second computing device when determining the second verification code matches the third verification code by the second computing device. The second deterministic random bit generator is the same as the first deterministic random bit generator.
