摘要： A method for determining proximity between a first device and a second device, the method comprising providing a first device storing a first device private key, the first device having an associated secure first device certificate storing secured information, the secured information comprising a first device public key corresponding to the first device private key, providing a second device storing a second device private key, the second device having an associated secure second device certificate storing secured information, the secured information comprising a second device public key corresponding to the second device private key, and a second device processing delay, providing a copy of the second device certificate to the first device, establishing a secure authenticated channel between the first device and the second device, sending a proximity challenge from the first device to the second device, the proximity challenge including a numeric challenge value, receiving the proximity challenge at the second device, processing the proximity challenge at the second device to produce the response to the proximity challenge, and sending the response to the proximity challenge from the second device to the first device, receiving the response to the proximity challenge at the first device, and performing the following at the first device verifying, at the first device, that the response to the proximity challenge is legitimate, determining a gross time between sending the proximity challenge and receiving the response to the proximity challenge, subtracting the second device processing delay from the gross time to produce a net response time, and comparing the net response time to a first threshold and determining whether the first device and the second device are in proximity based on a result of the comparing. Related methods and apparatus are also described.

摘要： A method for producing at least one ciphertext block from at least one plaintext block using a block cipher E and a key K , the method including receiving n plaintext blocks, wherein n is an integer greater than 0, setting Q 0 equal to an initial value, and for each plaintext block of the n plaintext blocks: computing Q i = E K ( Q i-1 ) XOR P i ; and computing C i = M(P i, Q i ), thereby producing n ciphertext blocks, wherein 0 P i denotes an i-th plaintext block of the n plaintext blocks, and C i denotes an i-th ciphertext block of the n ciphertext blocks, and M is a selector function which, for each bit C ij of block C i , selects a first argument of M if bit P ij is not to be encrypted, and selects a second argument of M if bit P ij is to be encrypted. Related apparatus and methods are also provided.
