There are plenty online definitions of \"checksum\" which prove you are on the right track:
===============================================================================
A value that is computed and that depends on the contents of a set of data. Checksums are stored or transmitted with the data. The checksum is used to detect if the data has been altered during transmission or when being stored and retrieved. Receiving programs recompute the checksum to compare with the checksum sent or stored with the data. Checksums may be more than one digit. They are not always the result of addition but may be the result of one or more computations involving addition, subtraction, multiplication, or division.

Numeric value used to verify the integrity of a block of data. The value is computed using a checksum procedure. A crypto checksum incorporates secret information in the checksum procedure so that it can\'t be reproduced by third parties that don\'t know the secret information.

(n.) The result of adding a group of data items that are used for checking the group. The data items can be either numerals or other character strings treated as numerals during the checksum calculation. The checksum value verifies that communication between two devices is successful.

Method for checking the integrity of transmitted data. A checksum is an integer value computed from a sequence of octets taken through a series of arithmetic operations. The value is recomputed at the receiving end and compared for verification.
www.zworld.com/documentation/glossary/intro.html

A number that represents a larger group of numbers in order to check for errors in data transmission. It is commonly used when downloading a program, as well as in error control protocols. The checksum is the result of a mathematical equation, such as adding all the numbers in a block together (although it is usually more complex than that).

Used in error detection, a checksum is a computation done on the message and transmitted with the message; similar to using parity bits.
www.rsasecurity.com/rsalabs/faq/B.html

A computed value which is dependent upon the contents of a packet. This value is sent along with the packet when it is transmitted. The receiving system computes a new checksum based upon the received data and compares this value with the one sent with the packet. If the two values are the same, the receiver has a high degree of confidence that the data was received correctly. [Source: NNSC]

Russian term (edited): c������� ���-����� � �����

Хэш-функции применяются широко, особенно в криптографии; все что угодно может быть. Например, легко может оказаться, что "суммарная" указывает на тип используемой хэш-функции. Я бы на вашем месте постарался проконсультироваться с заказчиком
(ненавижу файлы сообщений =)

Additive Hashing

This is where the hash value is constructed by traversing through the data and continually incrementing an initial value by a calculated value relative to an element within the data. The calculation done on the element value is usually in the form of a multiplication by a prime number.
