WebCryptographic algorithms are most commonly used in smart cards. The chip ensures security by checking cardholder credentials (typically a PIN code) and performing cryptographic operations. Very simple in term of architecture, these cards were initially embedded with the algorithm and an 8-bit core, running at few tens of megahertz.

Webkey cryptography for devices such as RFID tags is impossible to achieve. Our results show that outsourced computation makes it possible for such devices to carry out public-key cryptography. Without outsourcing, a device would need O(n) modular multiplications to carry out a modular exponentiation for an n-bit exponent.

WebCryptographic Operations in the TLS Protocol. There are two main phases of the TLS protocol: handshake and application record processing (Figure 2). The first phase is the handshake, which establishes a cryptographically secure data channel.
