Abstract: The application discloses an electronic operating device (100) arranged to protect communication between a consumer application (125) and a network-connected consumer device (300). The operating device protects a command message by signing the command message with a private key obtained from a key storage of the operating device (optionally also encrypting the command message with an encryption key), and sends the protected command message to the network controller (200). The network controller performs the verification of the signature of the command message such that legacy consumer devices without cryptgraphic capability can be used. The signature ensures that only authorised devices (100) can send commands to the consumer device (300).

Abstract: A method for performing an electronic transaction is disclosed. The method provides authentication data and authentication software to an electronic device and preferably stored in a secure storage location or other location inaccessible to the user or the operating system of the device. The authentication software is activated to generate a digital signature from the authentication data. Next, the digital signature is provided to the other transaction party.

Abstract: A method for performing an electronic transaction is disclosed. The method provides authentication data and authentication software to an electronic device and preferably stored in a secure storage location or other location inaccessible to the user or the operating system of the device. When digital data is requested from a transaction party that requests a digital signature, the authentication software is activated to generate said digital signature from the authentication data. Next, the digital signature is provided to the other transaction party, which then provides the requested digital data. The digital signature may be embedded in the requested and provided digital data. Further, a method for performing a verification of legitimate use of digital data is disclosed.

Abstract: In a method for performing an electronic transaction a first transaction part generates a digital signature and an encrypted digital signature. The second transaction party receives both signatures. The second party is enabled to verify the digital signature, but cannot verify or (re)generate the encrypted digital signature. A trusted third party is enabled to verify the encrypted digital signature if the digital signature is also provided, since the trusted third party cannot (re)generate the digital signature. Thus, no other party than the first transaction party can (re)generate both the digital signature and the encrypted digital signature. Therefore, no other party presenting himself as the first transaction party can be verified as being the first transaction party.

Abstract: A software application installation method installs a software application on a device such that the installed application can only be activated on said device. Thereto, an authorization application is installed as well on the device. During installation, the authorization application generates a software release code that is stored in a first and a second memory location, of which at least one is a memory location not accessible to a user. When the software application is later activated on the device, the authorization application compares the software release codes stored in said two memory locations. The application is only started if the software release codes correspond. Further, an authorization verification method is disclosed. A second party may verify the legitimacy of the installed application by storing device specific identification data and application specific installation data when a first connection is established and later comparing said data if a second or further connection is established.

Abstract: A method and a system for performing a transaction between at least one first party and at least one second party are disclosed. A data network connects data input/output terminals of the parties. In the data network, a secure and trusted transaction server is provided, in which a profile of the parties is registered, having a party identifier identifying a particular party, and authentication data for authenticating the party and data sent by the party. The parties communicate with each other through the transaction server by means of various transaction messages, which are digitally signed using a table of random numbers and a hashing operation, wherein the table of random numbers is generated by reading a token.
