Question

Difficulty: MediumElectronic Business and Data Interchange in Accounting

In electronic business accounting, the primary purpose of attaching a digital signature to an Electronic Data Interchange (EDI) financial document is to compress the file size for faster transmission across Value-Added Networks (VANs).

Answer: Answer

Answer

False. The main accounting and control function of a digital signature in EDI is to verify authenticity, ensure message integrity, and enforce non-repudiation, not file compression.
The statement incorrectly attributes data compression to digital signatures. In EDI and electronic business accounting, digital signatures serve critical internal control functions: verifying sender identity (authentication), preventing unauthorized data tampering during transfer (integrity), and legally binding the sender to the transaction (non-repudiation).

Step-by-Step Solution

1
Define the primary purpose of digital signatures in e-business accounting.
Digital signatures use cryptographic keys to authenticate the sender's identity, verify that the transaction contents were not altered during transmission, and ensure legal non-repudiation.
Security and internal control mechanisms are vital when executing paperless financial transactions over electronic networks.
2
Distinguish between security mechanisms and transmission efficiency tools.
Data compression tools reduce transmission payload size, whereas digital signatures add cryptographic hashes and certificates for security.
Confusing technical network optimization with accounting audit controls represents a misunderstanding of e-business security infrastructure.
