Abstract: Systems and methods are disclosed for authenticating electronic messages. A data structure is generated by a computer server which allows for the authentication of the contents and computer server identity of a received electronic message and provides a trusted stamp to authenticate when the message was sent. Data which can authenticate the message, the computer server identity, and the time the message was sent is included into a data structure which is called an Electronic PostMark (EPM).

Abstract: A method and apparatus for facilitating instant messaging utilizes a secure instant message group policy certificate issued by an instant messaging public key infrastructure policy certificate issuing unit. The secure instant messaging group policy certificate is received, such as through a local instant messaging secure public key infrastructure proxy, and contains data defining the group members, references to other groups, security controls and relevant data such as allowed algorithms. The secure instant messaging group policy certificate defines a plurality of different instant messaging groups, each identified by an instant messaging group identifier. Each instant messaging group identifier is associated with a plurality of instant message group number identifiers.

Abstract: Briefly, a method and apparatus for facilitating instant messaging generates (e.g. issues) an instant messaging public key cryptography policy certificate containing selected instant messaging public key cryptography policy control information. An instant messaging device obtains the instant messaging public key cryptography policy certificate through the use of a local instant messaging secure public key infrastructure proxy. Based on instant messaging policy control data in the instant messaging public key cryptography policy certificate, operations of the local instant messaging secure PKI proxy are controlled for outgoing and incoming instant messages. Hence, among other advantages, central enforcement of security policies for instant messaging users is provided.

Abstract: Briefly, an instant messaging secure PKI proxy provides public key-based secure instant messaging by intercepting messages to or from an instant messaging client, such as an instant messaging client running on a client device, and applies a public key-based cryptographic operation on the intercepted instant messages using at least a private key associated with an instant message originator or a public key associated with an instant message originator to produce an end-to-end public key infrastructure secured instant message. As such, the device and methods provide non-services repudiation and public key-based encryption services for content of instant messages during an instant message session helping to insure that the information will not be disclosed to unauthorized parties and assuring that the identities of all the participants are known and trusted without impairing local messaging clients.
