    • An e-mail firewall applies policies to e-mail messages transmitted between a first site and a plurality of second sites. The e-mail firewall includes a plurality of mail transfer relay modules for transferring e-mail messages between the first site and one of the second sites. Policy managers are used to enforce and administer selectable policies. The policies are used to determine security procedures for the transmission and reception of e-mail messages. The e-mail firewall employs signature verification processes to verify signatures in received encrypted e-mail messages. The e-mail firewall is further adapted to employ external servers for verifying signatures. External servers are also used to retrieve data that is employed to encrypt and decrypt e-mail messages received and transmitted by the e-mail firewall, respectively.
    • 电子邮件防火墙将策略应用于在第一站点和多个第二站点之间传送的电子邮件消息。 电子邮件防火墙包括用于在第一站点和第二站点之一之间传送电子邮件消息的多个邮件传送中继模块。 政策管理人员用于执行和管理可选择的政策。 这些策略用于确定电子邮件发送和接收的安全程序。 电子邮件防火墙采用签名验证过程来验证接收的加密电子邮件中的签名。 电子邮件防火墙还适用于使用外部服务器来验证签名。 外部服务器还用于检索用于加密和解密由电子邮件防火墙接收和发送的电子邮件消息的数据。

    • A method for facilitating a real estate transaction includes engaging an initiating party in communication with an initiated party regarding a property, where the parties are engaged for an engagement period. In this regard, the initiating party can be a buyer arrangement or a seller arrangement, with the initiated party being the other of the buyer arrangement and the seller arrangement. Thereafter, the engaged parties are restricted from communicating with other buyer arrangements and seller arrangements during the engagement period. Restricting the parties thereby facilitates the parties concluding a real estate transaction regarding the property. In addition, the method can further include insuring the buyer arrangement for a period of time against a loss of income due to a default of at least one tenant if the parties conclude a real estate transaction regarding an income-producing property including at least one tenant.
    • 促进房地产交易的方法包括使发起方与发起方就涉及财产的方式进行通信,当事人在参与期间进行参与。 在这方面,发起方可以是买方安排或卖方安排,发起方是买方安排和卖方安排的另一方。 此后,参与方在参与期限内不得与其他买方安排和卖家安排进行沟通。 限制双方因而有助于各方缔结有关该物业的房地产交易。 此外,该方法还可以包括如果双方缔结关于包括至少一个租户的收入产生的房地产交易的房地产交易,则保险买方安排一段时间以防止由于违约至少一个租户而造成的收入损失 。

    • A method and system are provided for secure document delivery over a wide area network, such as the Internet. A sender directs a Delivery Server to retrieve an intended recipient's public key. The Delivery Server dynamically queries a certificate authority and retrieves the public key. The public key is transmitted from the Delivery Server to the sender. The sender encrypts the document using a secret key and then encrypts the secret key using the public key. Both encrypted document and encrypted secret key are uploaded to the Delivery Server, and transmitted to the intended recipient. The intended recipient then uses the private key associated with the public key to decrypt the secret key, and uses the secret key to decrypt the document. In an alternative, equally preferred embodiment of the invention, the sender uses the public key to encrypt the document. In yet another embodiment, the server transmits the document to the Delivery Server for encryption.
    • 提供了一种方法和系统,用于在广域网(例如因特网)上的安全文档传送。 发件人指示传送服务器检索预期收件人的公钥。 交付服务器动态查询证书颁发机构并检索公钥。 公钥从发货服务器发送到发件人。 发送方使用秘密密钥对文档进行加密,然后使用公钥加密密钥。 加密文件和加密秘密密钥都被上传到传送服务器,并传送给预定的收件人。 然后,预期的接收者使用与公开密钥相关联的私钥来解密该秘密密钥,并且使用秘密密钥来解密该文档。 在本发明的另一方面,同样优选的实施例中,发送者使用公开密钥来加密文档。 在另一个实施例中,服务器将文档发送到传送服务器进行加密。

    • A server interacts with a sender to form a package which can include one or more attached data files to be sent to one or more recipients, and the server applies a policy established by a policy authority of the sender to the package. Since the server both forms the package through interaction with the sender and applies the policy, violations of the policy by the package can be brought to the sender's attention during an interactive session with the sender and before encryption of all or part of the package. As a result, the sender is educated regarding the policy of the sender's policy authority, and the sender can modify the package immediately to comport with the policy. The server delivers the package to intended recipients by sending notification to each recipient and including package identification data, e.g., a URL by which the package can be retrieved.
    • 服务器与发送者进行交互以形成可以包括要发送给一个或多个收件人的一个或多个附加数据文件的包,并且服务器将由发送者的策略机构建立的策略应用于包。 由于服务器通过与发送者的交互形式构成包,并且应用该策略,所以在与发送者的交互式会话期间以及在对所有或部分包进行加密之前,该包可能会引起发包方的注意。 因此,发件人对发件人的政策权限的政策进行了教育,发件人可以立即修改包,以符合政策。 该服务器通过向每个收件人发送通知并且包括包标识数据(例如,可以通过该URL检索包的URL)来将包发送给预期的收件人。
