摘要： A technique for efficient encryption for use with devices such as smartcards restricted in memory resource, including a calculation unit for reconstructing a large number of small primes, a sieving unit for checking the divisibility of an integer by small primes, a recoding unit for changing the representation of an integer, and a primality testing unit. The sieving unit eliminates “bad” candidates by checking their divisibility by small primes reconstructed by the calculation unit. The primality of the remaining candidates is tested using the primality testing unit. The primality testing unit uses the recoding unit to change the representation of prime candidates. The primality testing unit performs a primality test using the representation after change.

摘要： A signature system in which size of data to be transmitted is small and data can be processed efficiently in a Merkle signature system having high security. A processing part 112 of a smartcard 110 divides a message to be signed into groups of specific numbers of bits, starting from the first bit of the message. Then, respective partial one-time signatures of the groups are generated by encrypting each group by a one-way function processing part 112c. The partial one-time signatures are sequentially outputted to a verification apparatus through a interface part 113.

摘要： A technique which contributes to materialization of efficient encryption even with devices such as smartcards restricted in memory resource is provided. The system for generating cryptographic keys includes: a calculation unit for reconstructing a large number of small primes, a sieving unit for checking the divisibility of an integer by small primes, a recoding unit for changing the representation of an integer, a primality testing unit. First, the sieving unit eliminates “bad” candidates by checking their divisibility by small primes reconstructed by the calculation unit. After that, the primality of the remaining candidates is tested using the primality testing unit. The primality testing unit uses the recoding unit to change the representation of prime candidates. The primality testing unit performs a primality test using the representation after change. Thus, the number of operations for the primality test can be decreased without further memory requirements.

摘要： Using the same secret key for different secret operations in the frame of public key cryptosystems raises security problems because attackers can gain statistical information about the secret key. Indeed, when randomization techniques are used, the same secret key is randomized differently for every new operation, and since information leakage sums up, eventually, the attacker is able to recover the secret key.A system and method for using the same secret key of a public key cryptosystem several times comprising a recoding method which can generate several distinct representations for the secret key, where one representation is chosen as recoded secret according to a selection data. In addition, the pair consisting of the secret key and selection data is uniquely defined, resulting in the same recoded secret for every new encryption operation. As a consequence, information leakage does not sum up and the secret key can be securely re-used.

摘要： In the searchable encryption processing system, a data base server retaining data, a registration client which deposits the data into the data base server, and a search client which causes the data base server to search the data collaborate across a network, wherein the registration client, using a probabilistic encryption method which uses a mask using a homomorphic function and a hash value, deposits the encrypted data into the server, whereupon the search client, using probabilistic encryption which uses the mask which uses the homomorphic function for encryption of the search query, outputs the search query and non-corresponding data as search results without causing the data base server to unmask the mask and without allowing the frequency of occurrences of the data corresponding to the search to leak to the data base server.
