摘要： In an encrypted communication system that includes a first and a second device, the first device encrypts a 1st key using a public key of the second device to generate 1st encrypted data, which is then transmitted to the second device, receives 2nd encrypted data from the second device, which is then decrypted using a secret key of the first device to obtain a 2nd key, and generates, based on the 1st and 2nd keys, a 1st encryption key for use in communication with the second device. The second device encrypts a 3rd key using a public key of the first device to generate the 2nd encrypted data, which is then transmitted to the first device, receives the 1st encrypted data, which is then decrypted using a secret key of the second device to obtain a 4th key, and generates, based on the 3rd and 4th keys, a 2nd encryption key for use in communication with the first device. The first and second devices perform encrypted communication using the 1st and 2nd encryption keys.

摘要： A theft prevention system capable of preventing theft of a target object by disabling the authorized key of the target object in the case where the authorized key has been stolen. When the authorized key is lost, a mobile telephone 100 instructs a vehicle control device 300a to set a warning mode. On receipt of this warning mode instruction, the vehicle control device 300a sets warning mode, generates an electronic key, and transmits the generated electronic key to the mobile telephone 100, which receives and stores the electronic key. Once the warning mode is set in the vehicle, locking and unlocking are only possible using the electronic key. If the authorized key is found, the mobile telephone 100 instructs the vehicle control device 300a to set the normal mode. Upon receipt of this normal mode instruction, the vehicle control device 300a sets the normal mode in the vehicle. Once the normal mode is set in the vehicle, locking and unlocking are only possible using the authorized key.

摘要： Provided is a content distribution system that prevents different keys to be derived between an encryption apparatus and a decryption apparatus. A random-number generating unit 112d, in an encryption apparatus 110d, generates a random number s, and a first function unit 113d generates a functional value G(s) of the random number s, and generates a verification value a and a shared key K from the functional value G(s). An encryption unit 114d generates a first cipher text c1 of the verification value a using a public-key polynomial h, and a second function unit 115d generates a functional value H(a,c1) of the verification value a and the first cipher text c1, and a random-number mask unit 116d generates a second cipher text c2=s xor H(a,c1). A decryption unit 123d, in a decryption apparatus 120d, decrypts the first cipher text c1 using a secret-key polynomial f, to generate a decryption verification value a′. A third function unit 124d generates a functional value H(a′,c1) of the decryption verification value a′ and the first cipher text c1, and a random-number mask removal unit 125d generates a decryption random number s′=c2 xor H(a′,c1). A fourth function unit 126d generates a hash functional value G(s′) of the decryption random number s′, and generates a verification value a″ and a shared key K′ from the functional value G(s′) A comparison unit 127d outputs the shared key K′ if the decryption verification value a′ is equal to the verification value a″.
