  • Patent number: 8607073
    Abstract: A storage medium having an encrypting device, including an electronic memory area, a read-in device, a read-out device, a key memory, in which a secret key is or can be stored, an encrypting device, and a decrypting device. The read-in device is designed to encrypt any data input at the interface for storage in the memory area using the key stored in the key memory and to store said encrypted data in the memory area. The read-out device has a direct read-out channel, by means of which stored encrypted data can be output to the interface in encrypted form by circumventing the decrypting device, and a decrypting read-out channel, by means of which stored encrypted data in the memory area can be decrypted by means of the decrypting device using the key stored in the key memory or a decryption key stored in the key memory and corresponding to the key and can be output to the interface in decrypted form.
