About SME/KS

The SME/KS feature enables the protected transmission of messages over public domains by providing message encryption, decryption, digital signing, and signature verification. SME/KS uses Public Key Infrastructure (PKI) technology to ensure the confidentiality of message exchanges by digitally signing and encrypting messages when they are sent, and decrypting and authenticating messages when they are received.

SME/KS encrypts and decrypts messages using the Secure Multipurpose Internet Mail Extensions (S/MIME0 messaging format. For more information on the S/MIME format, see About S/MIME Cryptography

Compression reduces the physical size of string and binary file formats using Java-based mathematical equations that scan and index repetitive patterns. Most files contain repetitive patterns. For example, in a color image, the number and placement of repetitive colors are indexed. The information is indexed, which reduces the size of the file. When the file is decompressed, the index regenerates the patterns and reinflates the file to its original size.

SME/KS enables eGate to process events via S/MIME. SME/KS is interoperable with any other client application that supports S/MIME.

A SME/KS implementation adds the following security attributes to message transactions:

• Encryption and decryption

• Data compression and decompression

• Transaction privacy

• Message authentication

• Sender authentication

• Message nonrepudiation
