Protecting sensitive data in the field of symmetric key cryptography requires strong security against side-channel attacks. The confidentiality and integrity of cryptographic systems are seriously threatened by side-channel attacks, which take advantage of accidental information loss through a variety of physical channels. This research provides a comprehensive analysis of side-channel attacks and suggests an analysis method to highlight the vulnerability of a given symmetric algorithm. The relevance of side-channel attacks and their impact on cryptographic solutions are first discussed in the study. Following that, it concentrates on a well-known side-channel attack category which is Time Analysis attack. The simulation of this attack will be primarily tested on DES (Data Encryption Standard) algorithm. This research contributes to the present day attempts to strengthen the security of symmetric key cryptography by providing a thorough analysis of side-channel attacks.
