  • Protection against differential power analysis attacks involving initialization vectors
    Patent number: 11582021
    Abstract: Disclosed approaches for validating initialization vectors determining by a configuration control circuit whether or not an input initialization vector is within a range of valid initialization vectors. In response to determining that the initialization vector is within the range of valid initialization vectors, the configuration control circuit decrypts the ciphertext into plaintext using the input initialization vector and configures a memory circuit with the plaintext. In response to determining that the first initialization vector is outside the range of valid initialization vectors, the configuration control circuit signals that the first initialization vector is invalid.
