Abstract
A method comprises performing verification of an IM message sent using a specified Instant Messaging (IM) screen name and received by an information recipient after successful verification of authenticity of an authentication certificate received by the information recipient from the specified IM screen name. Verifying the IM message includes successfully verifying authenticity of the IM message using authentication information contained in the received authentication certificate. The IM message includes an encoded checksum for designated parts of the IM message. Performing verification of the IM message includes verifying authenticity of the encoded checksum.
Claims20
A method, comprising:
- performing verification of an IM message sent using a specified Instant Messaging (IM) screen name and received by an information recipient after successful verification of authenticity of an authentication certificate received by the information recipient from the specified IM screen name, wherein verifying said IM message includes successfully verifying authenticity of the IM message using authentication information contained in said received authentication certificate, wherein the IM message includes an encoded checksum for designated parts of the IM message, and wherein performing verification of the IM message includes verifying authenticity of the encoded checksum.
A system, comprising:
- at least one data processing device;
- instructions processable by said at least one data processing device;
- and
- an apparatus from which said instructions are accessible by said at least one data processing device;
- wherein said instructions are configured for enabling said at least one data processing device to perform operations for:
- performing verification of an IM message sent using a specified Instant Messaging (IM) screen name and received by an information recipient after successful verification of authenticity of an authentication certificate received by the information recipient from the specified IM screen name, wherein verifying said IM message includes successfully verifying authenticity of the IM message using authentication information contained in said received authentication certificate, wherein the IM message includes an encoded checksum for designated parts of the IM message, and wherein performing verification of the IM message includes verifying authenticity of the encoded checksum.
A computer-readable medium having tangibly embodied thereon and accessible therefrom a set of instructions interpretable by at least one data processing device, said set of instructions configured for causing said at least one data processing device to carry out operations for:
- performing verification of an Instant Messaging (IM) message sent using a specified IM screen name and received by an information recipient after successful verification of authenticity of an authentication certificate received by the information recipient from the specified IM screen name, wherein verifying said IM message includes successfully verifying authenticity of the IM message using authentication information contained in said received authentication certificate, wherein the IM message includes an encoded checksum for designated parts of the IM message, and wherein performing verification of the IM message includes verifying authenticity of the encoded checksum.
