Random data from GNSS signals and secure random value provisioning for secure software component implementations |
摘要 |
A method for verifying the integrity of navigation data used to produce random values for a white-box cryptography system including: receiving information from a navigation system; verifying the integrity of the received navigation information; extracting random information from the received navigation information; and performing a white-box cryptography operation using the extracted random information. Also, a method for determining that the random information samples used to produce random values for a white-box cryptography system have sufficient entropy, including: determining a number of random samples to initially collect; collecting the number of random samples from an external random number generator; calculating the entropy of the collected random samples; encrypting or hashing the collected random samples using the white-box cryptography system and a secret key; and performing a white-box cryptography operation using the encrypted collected random samples. |
