RANDOMNESS FOR ENCRYPTION OPERATIONS |
摘要 |
Methods, systems, and computer programs for generating random values for encryption operations are described. In some examples, information from a message to be encrypted can be used to refresh the state of a pseudorandom generator. In some aspects, a state parameter of the pseudorandom generator is modified based on information in the message. Modifying the state parameter changes the state parameter from a prior state to a refreshed state based on the information in the message. A random output value is obtained by the pseudorandom generator in the refreshed state. The message is encrypted based on the random output value. |
