SSL/TLS provides encryption and authentication for secure internet communications. It originated from efforts by IETF, ANSI, and Netscape in the 1990s. SSL/TLS establishes a secure channel through a handshake to negotiate encryption keys before data transfer. SET builds on SSL/TLS to provide additional privacy, authentication, and integrity specifically for online credit card transactions through the use of digital signatures and certificates. It establishes separate encryption for payment and order information that is only revealed to authorized parties.

This is an introductory presentation to SSL and the basics of secure communication over the web. It walks over the concepts of how SSL works and the various methods for implementing a safe communication channel. It explains the mechanisms of web negotiation, before starting any web transaction between remote hosts.
SSL is an acronym for Secure Sockets Layer. It is a protocol used for authenticating and encrypting web traffic. For web traffic to be authenticated means that your browser is able to verify the identity of the remote server.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

11. SSL (Secure Sockets Layer)
• NOT a payment protocol -- can be used for any secure
communications, like credit card numbers
• SSL is a secure data exchange protocol providing
– Privacy between two Internet applications
– Authentication of server (authentication of browser optional)
• Uses enveloping: RSA used to exchange DES keys
• SSL Handshake Protocol
– Negotiates symmetric encryption protocol, authenticates
• SSL Record Protocol
– Packs/unpacks records, performs encryption/decryption
• Does not provide non-repudiation
13. 13
SET (Secure Electronic Transactions)
• Provides a secure communications channel among all the parties involved in a
transaction: Customer, Seller, Customer’s credit provider, Seller’s bank.
• Provides trust by the use of X.509v3 certificates.
• Ensures privacy because information is only made available to the parties that need it.
* Cardholder account authentication to the Merchant (Cardholder must have a
Certificate issued by the credit company). Merchant may issue a temporary Certificate
to issue the session is not hijacked).
* Verifies Merchant's relationship with financial institution.
* Integrity of data customer sends to Merchant (order info tied to funds transfer).
14. 14
SET - Steps in a Transaction
1. Customer opens account with credit company or bank.
2. Bank issues X.509 cert. to the Customer with RSA Keys.
3. Merchant has two certificates, signing and key exchange.
----
4. Customer places an order.
5. The Merchant sends the customer a copy of his certificate.
6. The Customer sends Order Information (OI) encrypted so the Merchant can read
it, and Payment Information (PI) encrypted so the Merchant can not read it.
---
7. Merchant requests payment by sending PI to the “Payment Gateway” (who can
decrypt it) and verifies Customer’s credit.
8. Merchant confirms the order to the Customer.
9. Merchant ships goods to Customer.
10. Merchant sends request for payment to the Payment Gateway which handles
transfer of funds.

24. SSL Vs. SET
• A part of SSL (Secure Socket Layer) is available on
customers’ browsers
– it is basically an encryption mechanism for order taking, queries and
other applications
– it does not protect against all security hazards
– it is mature, simple, and widely use
• SET ( Secure Electronic Transaction) is a very
comprehensive security protocol
– it provides for privacy, authenticity, integrity, and, or repudiation
– it is used very infrequently due to its complexity and the need for a
special card reader by the user
– it may be abandoned if it is not simplified/improved
25. SET Vs. SSL
Secure Electronic Transaction (SET) Secure Socket Layer (SSL)
Complex Simple
SET is tailored to the credit card
payment to the merchants.
SSL is a protocol for general-
purpose secure message
exchanges (encryption).
SET protocol hides the customer’s
credit card information from
merchants, and also hides the order
information to banks, to protect
privacy. This scheme is called dual
signature.
SSL protocol may use a certificate,
but there is no payment gateway.
So, the merchants need to receive
both the ordering information and
credit card information, because
the capturing process should be
initiated by the merchants.
26. Payments, Protocols and Related Issues
• SET Protocol is for Credit Card Payments
• Electronic Cash and Micropayments
• Electronic Fund Transfer on the Internet
• Stored Value Cards and Electronic Cash
• Electronic Check Systems
27. • Security requirements
Payments, Protocols and Related Issues (cont.)
Authentication: A way to verify the buyer’s identity before
payments are made
Integrity: Ensuring that information will not be accidentally or
maliciously altered or destroyed, usually during transmission
Encryption: A process of making messages indecipherable
except by those who have an authorized decryption key
Non-repudiation: Merchants need protection against the
customer’s unjustifiable denial of placed orders, and customers need
protection against the merchants’ unjustifiable denial of past payment

29. Secure Electronic Transaction (SET) Protocol
1. The message is hashed to a prefixed length of message digest.
2. The message digest is encrypted with the sender’s private signature
key, and a digital signature is created.
3. The composition of message, digital signature, and Sender’s
certificate is encrypted with the symmetric key which is generated at
sender’s computer for every transaction. The result is an encrypted
message. SET protocol uses the DES algorithm instead of RSA for
encryption because DES can be executed much faster than RSA.
4. The Symmetric key itself is encrypted with the receiver’s public key
which was sent to the sender in advance. The result is a digital
envelope.

31. Five Security Tips
• Don’t reveal your online Passcode to anyone. If you think your
online Passcode has been compromised, change it immediately.
• Don’t walk away from your computer if you are in the middle of a
session.
• Once you have finished conducting your banking on the Internet,
always sign off before visiting other Internet sites.
• If anyone else is likely to use your computer, clear your cache or
turn off and re-initiate your browser in order to eliminate copies of
Web pages that have been stored in your hard drive.
• Banks strongly recommends that you use a browser with 128-bit
encryption to conduct secure financial transactions over the
Internet.
