Applications of Cryptography

Historically, the sole purpose of cryptography was to assure secrecy. By the rise of e-banking and e-commerce applications, the use of cryptography for integrity protection surpasses its use for secrecy. For instance in electronic funds transfer, without appropriate cryptographic countermeasures, an error in a single bit could literally cause millions of dollars to be erroneously credited or debited.

Most of you might already know how widespread the use of cryptography in the Internet at least by hearing the acronyms of security protocols such as SSL, SSH, S/MIME etc. Maybe the less known is the fact that cryptography is used in almost every electronic device we have today (mobile phones, pay-TV decoders, game consoles, car keys, door access cards, burglar alarms etc.)

Cryptography is also closely linked to the problem of authentication. For instance it becomes almost a standard to use it in order to strengthen the security of password based authentication schemes.

Digital signatures, digital money and some other applications are waiting to be adopted by Internet users. Other more exotic cryptography applications include e-auction, e-voting, e-passports and some other e’s.
