Abstract:
With the rapid advances in security threads, more
reliable security techniques have become the business necessity.
The security services must assure that the communication is not
refered with in such a way that the party can masquerade for the
purpose of unauthorized transmission or reception. To maintain
the security services (confidentiality, authenticity and integrity),
the security mechanisms such as digital signature and
encipherment should be used. This system describes digital
signature and encipherment to protect the information
transmission for secure communication system. The purpose of
this system is to transport information reliably across an
insecure channel and to ensure complete confidence between
participants. To implement this system, SHA-1 (Secure Hash
Algorithm), RSA(Asymmetric Algorithm) and DES(Symmetric
Algorithm) are used.
