Patent ID: 8824674

Claim:
An information processing apparatus, comprising: a common key generating section to generate a common key; an original information encrypting section to encrypt original information based on the common key; a key storage section to store a public key used to encrypt the common key and a private key used to decrypt the common key; a common key encrypting section to encrypt the common key with the public key; a common key extracting section to extract a common key from an encrypted common key using the private key; a decryption processing section to decrypt encrypted information corresponding to the original information with the common key extracted from the encrypted common key; an encryption signature generating section to generate an encrypted signature using the private key; a secure transport core to perform encrypted communication via a communication network using the common key, wherein the decryption processing section decrypts encrypted link information received via the secure transport core using the private key to extract a corresponding common key, and decrypts, using the corresponding common key, encrypted information received via the secure transport core to extract corresponding original information.
