The generating unit refers to specification information, which specifies the communication device belonging to a group from among a plurality of communication devices, and generates identification information, which enables identification of the communication device specified in the specification information, by implementing, from among a plurality of generation methods for generating the identification information, a generation method in which the size of the generated identification information is smaller than the other generation methods. The sending unit sends the identification information to a plurality of communication devices. | 2016-12-29 |
20160380765 | QUANTUM ENABLED SECURITY FOR OPTICAL COMMUNICATIONS - The present invention provides a quantum-enabled security (QES) protocol which creates a revolutionary new cybersecurity capability: quantum (single-photon) communications are integrated with optical communications to provide a strong, innate security foundation at the photonic layer for optical fiber networks or free-space optical communications. The new protocols will also allow the formation of ad hoc coalitions of users in order to deliver quantum-enabled security users between users who may not have direct quantum communications. | 2016-12-29 |
20160380766 | ENCRYPTION SYSTEM WITH A GENERATOR OF ONE-TIME KEYS AND A METHOD FOR GENERATING ONE TIME-KEYS - A computer-implemented method for irreversible generating of distinct one-time encryption keys. For each subsequent operation of generating the one-time encryption key, the method comprises the following steps, performed with a one-time key generator: reading previously stored values P and Q to obtain read values P and Q, wherein the values P and Q are probable prime numbers; modifying the read values P and Q by using a modifier M and an additive operation, including size adjustment to obtain modified values P and Q; generating, based on the modified values P and Q, new values P and Q as probable prime numbers; storing the new values P and Q as stored values P and Q; executing a multiplication operation on the stored values P and Q to determine a new value N; and providing the new value N as a new component of the one-time encryption key. | 2016-12-29 |
20160380767 | RE-ENCRYPTION KEY GENERATOR, RE-ENCRYPTION APPARATUS, ENCRYPTION APPARATUS, DECRYPTION APPARATUS, AND STORAGE MEDIUM - According to one embodiment, a re-encryption key generator which generates the re-encryption key based on the first private key, the second re-encryption key generation key, and a plurality of random numbers. The second re-encryption key generation key comprises a plurality of system-specific values and the second private key. The re-encryption key includes an exponent having a numerator portion and a denominator portion or a scalar having a numerator portion and a denominator portion. The numerator portion is in form of a linear coupling of the second private key on which at least one of a plurality of private values specifying relations between the system-specific values and the random numbers is allowed to act. The denominator portion is the first private key. | 2016-12-29 |
