Abstract
An onboard computer system includes a first onboard computer configured to store a first public key certificate of a data delivering apparatus, a second onboard computer, and a secure element configured to store a second public key certificate relative to a second secret key used to generate the first public key certificate. The secure element verifies the first public key certificate by use of the second public key certificate. The first onboard computer includes an encryption processor configured to verify a first electronic signature attached to data delivered from the data delivering apparatus by use of the first public key certificate which is successfully verified by the secure element. The data attached with the first electronic signature, which is successfully verified by the encryption processor, is applied to the first onboard computer or the second onboard computer.
