Abstract: Disclosed is a method for mutual authentication between a station, having a digital rights agent, and a secure removable media device. The digital rights agent is configured to initiate mutual authentication by sending a message to the secure removable media device. The secure removable media device is configured to encrypt at least a first random number using a public key associated with the digital rights agent. The digital rights agent is configured to decrypt the encrypted first random number, and encrypt at least a second random number and a first hash based on at least the first random number. The secure removable media device is configured to decrypt the encrypted second random number and the first hash, verify the first hash to authenticate the digital rights agent, and generate a second hash based on at least the second random number. The digital rights agent is configured to verify the second hash to authenticate the secure removable media device.

Abstract translation: 公开了一种具有数字版权代理的站和安全可移动媒体设备之间的相互验证的方法。 数字版权代理被配置为通过向安全可移动媒体设备发送消息来发起相互认证。 安全可移动媒体设备被配置为使用与数字版权代理相关联的公钥来加密至少第一随机数。 数字版权代理被配置为对加密的第一随机数进行解密，并且至少基于第一随机数加密至少第二随机数和第一哈希。 安全可移动媒体设备被配置为对加密的第二随机数和第一散列进行解密，验证第一散列以验证数字版权代理，并且至少基于第二随机数生成第二散列。 数字版权代理被配置为验证第二散列以验证安全可移动媒体设备。
