    • A method of authenticating and encrypting a client-server communication is provided. Two one-time passwords (OTP1 and OTP2) are generated from a cryptographic token. An encryption key (K_ENC) and a MAC key (K_MAC) are generated based on OTP2. The client data are prepared and protected using K_ENC and K_MAC. A request message is sent from the client to the server, and contains the protected client data, a cryptographic token identifier and OTP1. OTP1 is validated at the server, and OTP2 is generated at the server upon successful validation. K_ENC and K_MAC are derived from OTP2 at the server. The request message is processed and result data is generated. The result data is encrypted using K_ENC and a digest is created using K_MAC. The encrypted result data is sent to the client, and is decrypted using K_ENC and the authenticity of the result data is verified using K_MAC.
    • 提供了认证和加密客户端 - 服务器通信的方法。 从加密令牌生成两个一次性密码(OTP1和OTP2)。 基于OTP2生成加密密钥(K_ENC)和MAC密钥(K_MAC)。 使用K_ENC和K_MAC准备和保护客户端数据。 请求消息从客户端发送到服务器,并包含受保护的客户端数据,加密令牌标识符和OTP1。 OTP1在服务器上进行验证,成功验证后会在服务器上生成OTP2。 K_ENC和K_MAC从服务器上的OTP2派生。 处理请求消息并生成结果数据。 使用K_ENC对结果数据进行加密,并使用K_MAC创建摘要。 将加密的结果数据发送到客户端,并使用K_ENC进行解密,并使用K_MAC验证结果数据的真实性。
