摘要： A method to exchange and authenticate public cryptographic keys between parties that share a common but secret password. The parties exchange public keys, where the public keys are accompanied by hashed values based on the keys, the password, and random numbers. Each party then encrypts its random number using the public key of the other party, and the encryptions are exchanged. Based on the received encryptions and the known password, each party then re-computes the hashed value received from the other party, and compares the re-computed hashed value with the received hashed value. If the two are the same, the public key that accompanied the hashed value is judged authentic.

摘要： Methods, systems and computer program products are provided which generate a cryptographic key utilizing user specific information to generate a user dependent key. The user specific information may be a user identification or biometric information associated with a user. In particular embodiments of the present invention a seed value is modified with biometric information to generate a user dependent key value. In alternative embodiments a key value is hashed with user specific information or user specific information is hashed and then combined with the key value to generate the user dependent key value. In still another embodiment of the present invention the space of potential key values is divided into subspaces and the subspaces assigned based on user specific information. A key value is then generated from the assigned subspace. Thus, the generated key values for different users are guaranteed to be disjoint.

摘要： A method to distribute and authenticate public encryption keys. A client concatenates its ID, its public key, and a secret password known to the client and a server, and hashes the result. The client forms an extended concatenation including the ID, the public key, and the hashed value, and sends the extended concatenation to the server. The server reads the ID and public key, and re-computes the hashed value based on its own knowledge of the password. If the received and the computed hashed values are the same, the server concludes that the client's public key is authentic. An analogous process enables the server to distribute its public key, and enables the client to authenticate the server's distributed public key.
摘要翻译：一种分发和验证公共加密密钥的方法。客户端连接其ID，其公钥和客户机和服务器已知的秘密密码，并将结果进行散列。客户端形成包括ID，公钥和散列值的扩展级联，并将扩展级联发送到服务器。服务器读取ID和公钥，并根据自己的密码知道重新计算散列值。如果接收的和计算的散列值相同，则服务器断定客户端的公钥是可信的。类似的过程使服务器能够分发其公钥，并使客户端能够对服务器的分布式公钥进行身份验证。
