<p>The device has an encryption/decryption unit (20) to encrypt data words and a control bit vector, of a redundancy unit (12), to obtain encrypted data words and control bit vector. The unit (20) decrypts the encrypted words and vector to obtain decrypted data words and control bit vector. The units (12, 20) are placed before a control unit (14) that forms a total bit vector from the decrypted words and vector. The unit (14) creates, by multiplication of a binary control matrix by the total bit vector, a syndrome bit vector used to check the integrity of the total bit vector. Independent claims are also included for the following: (1) a method for protecting the integrity of data (2) a computer program with a program code for the execution of a method for protecting the integrity of data.</p> |
