摘要： The object is to enable cipher communication even when a cipher key in a one-time pad cipher (Vernam cipher) is running short. A one-time pad encrypting part encrypts communication data by the one-time pad cipher by sequentially using part of a one-time pad cipher key stored in a one-time pad cipher key storage part, to generate encrypted data. A block-encrypting part encrypts communication data by a block cipher by using a block-cipher key stored in a block-cipher key storage part, to generate encrypted data. An encryption control part controls whether the communication data is to be encrypted by the one-time pad encrypting part, or by the block-encrypting part, depending on a remaining bit count of the one-time pad cipher key stored in the one-time pad cipher key storage part.
摘要翻译：即使在一次性密码（Vernam cipher）中的密码密码短的情况下，也可以进行密码通信。一次性加密部分通过依次使用存储在一次性加密密钥存储部分中的一次性密码密码密钥的一部分来加密通过一次性加密密码的通信数据，以生成加密数据。块加密部分通过使用存储在块密码密钥存储部分中的块密码密钥通过块密码加密通信数据，以生成加密数据。加密控制部分根据存储在一次性加密部分中的一次性加密密码密钥的剩余比特数来控制是否由一次加密部分加密通信数据，或者通过块加密部分垫密码存储部分。

摘要： A communication terminal that can adjust which section of a one-time pad cipher key is used and achieve cipher communication when there is a possibility that the one-time pad cipher keys are not completely matched between communication terminals. A cipher key transfer device acquires a one-time pad cipher key from a key sharing system, divides the acquired one-time pad cipher key with a predetermined number of bits, and transfers the same to a mobile communication terminal after converting the same into one-time pad cipher key cartridges. Along with the partner's terminal, the mobile communication terminal negotiates which one-time pad cipher key cartridge will be used to perform cipher communication, decides the one-time pad cipher key cartridge to be used, and begins cipher communication.

摘要： In distribution and sharing of a cipher key to be used when performing encrypted communication among a plurality of terminals, to share a cipher key without the need for each terminal to constantly hold and manage a large number of keys. Also, to shorten the time needed to start terminal-to-terminal encrypted communication. Also, to improve the portability of the terminal. A key management server 1 sends by broadcast communication a cipher key, which is specific to each set of terminals that perform encrypted communication, one-sidedly to the respective terminals. The key management server 1 sends, by broadcast communication, cipher key data obtained by encrypting the cipher key by using a device public key which is the public key of an addressed terminal. Each terminal acquires cipher key data addressed to itself and decrypts the acquired cipher key data, thus obtaining a cipher key.
