An interactive mutual authentication protocol, which does not allow shared secrets to pass through untrusted communication media, integrates an encryption key management system into the authentication protocol. The server encrypts a particular data random key by first veiling the particular data random key using a first conversion array seeded by a shared secret, and then encrypting the veiled particular data random key. The client decrypts and unveils the particular data random key using the shared secret, and returns a similarly veiled version of the particular data random key using a second conversion array seeded by a shared secret. Access to the shared secret indicates authenticity of the stations. The procedure may be repeated for a second shared secret for strong authentication, without allowing shared secrets to pass via untrusted media.
