Secure electronic transactions (SET)
Secure Electronic Transaction (SET) is an open encryption and security specification designed to protect credit card transactions on the Internet. It provides confidentiality, integrity, authentication of cardholders and merchants, and uses public key infrastructure. SET involves certificates, dual signatures to link orders and payments, purchase requests from customers to merchants to payment gateways for authorization, and capture of funds transfer. The payment gateway verifies all parties and encrypts/decrypts information before authorization and funds transfer.
Info hiding
Steganography is the art of hiding information in plain sight. It differs from cryptography which only encrypts messages to hide their meaning. Common steganography techniques include least significant bit substitution, discrete cosine transform, and discrete wavelet transform which hide data in images by altering pixel values. These techniques aim to conceal the very existence of hidden messages within digital files like images, audio, and text. Watermarking also embeds hidden signatures but aims to prove ownership rather than full concealment like steganography. Modern steganography tools take advantage of digital file formats to covertly communicate secret messages.
Encryption And Decryption
This document discusses encryption and decryption. It was developed by four students and submitted to their professor. The document introduces encryption as converting plaintext to ciphertext and decryption as converting ciphertext back to plaintext. It explains that encryption uses a key to scramble the plaintext and decryption uses the same key to unscramble the ciphertext to retrieve the original plaintext. The document also briefly mentions the feasibility study, methodology, purpose of providing security, and system requirements for the encryption/decryption software.
Block Ciphers Modes of Operation
The document discusses several modes of operation for block ciphers and stream ciphers. It explains that block cipher modes like CBC, CFB, OFB, and Counter Mode require an initialization vector (IV) to provide randomization and prevent identical plaintext blocks from encrypting to the same ciphertext. The IV must be transmitted along with the ciphertext and never reused with the same key. Stream ciphers like RC4 generate a pseudorandom key stream that is XORed with plaintext bytes to produce ciphertext.
Introduction to Mobile programming(J2ME)
J2ME is a Java platform for small computing devices like mobile phones and PDAs. It uses a stripped-down Java API and virtual machine called CLDC. The J2ME architecture has three layers - configuration, profile, and MIDP. The configuration defines the JVM, profiles provide features for device classes, and MIDP is the most popular profile for mobile information devices. MIDP applications are called MIDlets, which are packaged in JAR files along with optional JAD descriptor files.

Study of Java Card and its Application
Sun Microsystems defined a set of specifications for a subset of Java technology to create applications for them, Java Card applets. A device that supports these specifications is referred to as a Java Card platform. On a Java Card platform, multiple applications from different vendors can coexist securely. The Java Card platform is the tiniest of Java targeted for embedded devices. It is an open, interoperable platform for smart cards and secure tokens. The technology is widely used in SIM cards (it's used in GSM mobile phones) and ATM cards. Java Card gives users the ability to program a device and make it application specific and lets smart card developers use a common card platform. Smart cards, unlike magnetic stripe cards, can carry all necessary functions and information on the card; therefore, they do not require access to remote databases at the time of the transaction.

eSmartlock - an antipiracy dongle with integrated DRM functionalities
eSmartlock is a complex prototype, which demonstrates the use of a Java Card based smartcard dongle as an integrated anti-piracy module and networked DRM engine; plus offering a hardware toolkit that can enhance the security of SSL backed transactions; authenticate timeStamp receptors; function
as a digital eSignature validator over commercial off-the-shelf software products - all in one: Forming an
integrated system that allows users of an application to operate in a closed-user-group setting with their
software producer or vendor; either online or even off-line.
Why? Apart from antipiracy security, the eSmartLock networked DRM model supports a diverse variety
of billing options like: leasing, renting, TimeCrediting, pay-as-you-use ValueCrediting, remote feature unlock, full
feature demo use. It can provide controlled crypto Web access to your eShop; or even secure CD/DVD offline
content access. For high-security conscious users, eSmartLock can encrypt local file Save/Load operations
with internal self-generated keySets; uniquely binding saved data to a specific eSmartLock card. It can be used
in a Server - Client configuration (Trusted Third Party – Key Distribution Center), over a LAN or WAN (extranet)
to authenticate other eSmartLock cards, establish encryption channels between eSmartLocked network nodes
and assist the verification of signed content – all in a single JavaCard applet.
