A sending computer system generates a message and creates one or more security tokens to encrypt portions of the message. The computer system includes in the message a markup language identifier for the one or more security tokens used for encryption, and includes identification of the value type used to create the tokens. The computer system then serializes at least the portion of the message that identifies the one or more security tokens, without serializing other portions of the message that aid relaying of the message to a receiving computer system. A receiving computer system deserializes at least the portion of the message that identifies the one or more security tokens, and then uses deserialized token data to decrypt encrypted portions of the message. Each created security token can be made with customized data and fields, and can be made with a customized value type.

A type system includes a dual representation for basic data types. One representation is the basic data type representation common to such basic built-in data types, known as an unboxed value type or simply as a value type. Each of the basic data types also has a boxed representation that can be stored in the object hierarchy of the type system. This dual representation can also be extended to user-defined types, so that user-defined types may exist both as an unboxed value type and as an object within the object hierarchy of the type system. This dual representation allows the compiler and/or runtime environment to select the most effective and efficient representation for the data type depending on the particular need at the moment.
