  • Patent number: 9571273
    Abstract: A method and system for accelerated decryption of a cryptographically protected user data unit, wherein a transmitter initially generates a cryptographic key that is provided with a related key identification. The transmitter then performs asymmetrical encryption of the generated cryptographic key using a public cryptographic key and encryption of at least one user data unit using the generated cryptographic key. The encrypted user data unit, the asymmetrically encrypted cryptographic key and the related key identification of the cryptographic key are transported to a receiver that decrypts the received asymmetrically encrypted key using a private key, if verification of the received related key identification of the cryptographic key indicates the cryptographic key is not present in a decrypted state in the receiver. The receiver then decrypts the received cryptographically encrypted user data unit using the cryptographic key in the receiver or with the cryptographic key decrypted using the private key.

  • Patent number: 9542537
    Abstract: A method and system for confidentially providing a software component which is encrypted using a secret cryptographic key of a software component manufacturer, and the key is then encrypted using a first cryptographic system key, wherein the encrypted software component and the encrypted key are transported by the software component manufacturer to a destination system device. After decrypting the transported encrypted key using a second cryptographic system key, the transported encrypted software component is decrypted using the decrypted key, wherein the decrypted software component is provided for execution on the destination system device. The method can be used to protect source codes or object codes of a developed software component from access by a third party and still allows for processing using standard tools.

  • Patent number: 9400636
    Abstract: An apparatus for calculating a result of a scalar multiplication of a reference number with a reference point on an elliptic curve includes a random number generator and processor. The random number generator generates a random bit. The processor calculates the result of the scalar multiplication based on a calculation algorithm using a first auxiliary variable storing a first interim result representing an integer multiple of the reference point or a coordinate of an integer multiple of the reference point and a second auxiliary variable storing a second interim result representing another integer multiple of the reference point or a coordinate of another integer multiple of the reference point. The processor swaps a value stored by the first auxiliary variable and a value stored by the second auxiliary variable during calculation of the result of the scalar multiplication, if a swap condition depending on the generated random bit is fulfilled.
