Claim 5:
6. The receiver device of claim 4, wherein the receiver device is configured to determine a random value and to determine said private session key by applying an exponentiation function of a base equal to the receiver partial private key and an exponent equal to said random value, said two public session keys comprising a first public session key and a second public session key, the receiver device being configured to determine said first public session key by applying an exponentiation function of a base equal to the output of an application of the first cryptographic hash function to a trusted center identifier and an exponent equal to said random value, and to determine said second public session key by applying an exponentiation function of a base equal to the trusted center public key and an exponent equal to said random value.
