Zusammenfassung:To provide an information processing device, a server device, a communication system, a communication method, and a program that can perform communication using individual keys without writing individual information in advance.SOLUTION: An information processing device includes: a communication unit that communicates with a communication destination server device; a storage unit that stores a master key; an individual key generation unit that generates an individual key using the master key and a predetermined ID; and an information processing unit that performs communication with the server device using the individual key as a common key. The individual key generation unit generates a first individual key used for authentication of an information processing device by the server device and a second individual key to be used for authentication of the server device by the information processing device on the basis of the combination of the same master key and the predetermined ID.SELECTED DRAWING: Figure 2 【課題】個別の情報を予め書込むことなく、個別鍵を用いた通信を行うことができる情報処理装置、サーバ装置、通信システム、通信方法、及びプログラムを提供する。【解決手段】通信先のサーバ装置と通信する通信部と、マスタ鍵を記憶する記憶部と、前記マスタ鍵と所定のIDとを用いて、個別鍵を生成する個別鍵生成部と、前記個別鍵を共通鍵とした通信を前記サーバ装置と行う情報処理部と、を備え、前記個別鍵生成部は、前記サーバ装置による情報処理装置の認証に用いる第1の個別鍵と、前記情報処理装置による前記サーバ装置の認証に用いる第2の個別鍵と、を、同一の前記マスタ鍵と前記所定のIDとの組合せに基づいて生成する。【選択図】図2
