通信设备、通信方法、通信系统和记录介质
Abstract:
本发明在维持加密通信安全的同时减少了加密处理负荷的影响。为此，通信设备(100)配备有：加密方法选择单元(101)，用于根据同步精度选择加密方法，该加密方法对加密通信中使用的加密处理引起不同处理负荷，加密精度表示将用于给定设备和另一设备之间的加密通信中的加密方法能够在其被改变的次数；加密处理单元(102)，用于通过使用所选择的加密方法对给定设备和其他设备之间的通信数据进行加密处理和/或解密处理。
Abstract(English):

The present invention reduces the impact from the load of encryption processing while maintaining the safety of encrypted communication. To this end, a communication device (100) is equipped with: anencryption method selection unit (101) for selecting encryption methods which entail different processing loads for the encryption processing used in encrypted communication, according to the synchronization accuracy, which expresses the quantity of times at which it is possible to change the encryption method to be used in encrypted communication between a given device and another device; and anencryption processing unit (102) for subjecting the communication data between the given device and the other device to encryption processing and/or decryption processing by using the selected encryption method.
