One of the most popular Internet services is electronic mail (e-mail).
At the beginning of the Internet era, the messages sent by electronic mail were short and consisted of text only.
Today, electronic mail is much more complex. It allows a message to include text, audio, and video.
It also allows one message to be sent to one or more recipients.

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).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
4. Improvements on SMTP
• Sender Policy Framework(SPF) – It is an email
validation system that tries to prevent spam by
detecting spoofing, by verifying sender’s IP address.
The domain administrators are expected to designate
hosts in that domain that are legitimate hosts.
• Domain Keys Identified Mail(DKIM) – It is a
method of associating a domain name to the email
message to make someone responsible for the email.
This responsibility is set by using digital signatures.
5. Secure Email
• PGP – 1991 – Phil Zimmerman
• It uses signing, encryption, certificates etc. to create
secure environments – for email or for encrypted file
systems etc.
• Public key authentication – decentralized
• Web of Trust
7. Assumptions in Web of Trust
• In order to verify the key, the assumption made is
that everyone signs the key of others
• Also everyone submits these signatures to the key
servers.
9. Off the record messaging
• Cryptographic protocol used to provide strong
encryption for instant messaging and email
• It uses a combination of AES symmetric key
encryption, Diffie-Hellman key exchange, and SHA1 hash function.
10. Features of OTR systems
• Encryption
• Authentication
• Deniable Encryption
• Perfect Forward Secrecy
11. Invisible Internet Project
• Provides a layer that serves secure
communication/data transfer mechanism
• Introduced in 2003 as a beta software
• Not reviewed yet
• No anonymity guaranteed
13. Bitcoin
• Open source decentralized Peer to Peer currency
• No central authority
• Not designed for anonymity
• Proof of work
• Mining
14. Bitmessage
• Based on Bitcoin, although it is designed to handle a
different application
• It differs from the protocols based on SMTP as it is
based on the concept of EGE or “Everyone Gets
Everything”
• Using this concept, Bitmessage can not only mask
the message body but also the metadata associated
with the message i.e. the sender and receiver
15. EGE
• No end points to a message
• Encrypt the message and drop it into the block chain
of messages
• All the active users try to decrypt the message.
• Only the intended recipient will be able to decrypt
the message.
16. Other services of Bitmessage
Broadcasting
•Since Bitmessage is based on the concept of EGE,
broadcasting a message comes naturally
•The users have to get the password of the channel
from some forum or word of mouth – and then they
will be able to decrypt the messages using the password
17. Chans
•Chans or channels are anonymous chat rooms
•Users can simply encrypt using the public key of the
chat room and post it
•Completely anonymous
18. Perfect Forward Secrecy
• An intruder can store all the encrypted conversations
and later when he eventually breaks or somehow
gets the private key, all the previously encrypted
information is lost
• This is a concern in almost all the PKI systems
• In Bitmessage this concern is even more pronounced
as anyone can store the block chains easily
19. • Bitmessage doesn’t provide PFS
• However, this can be supported in Bitmessage using
and implementation of key rotation
• Every message that is sent has to be sent using a new
key. These are called ephemeral keys
20. Message Retention
• In Bitmessage, the messages are retained for two
days before they are deleted
• The sender expects an acknowledgement from the
receiver which confirms the delivery of the message
• If the receiver doesn’t check his mailbox in two days
that the message was sent, the messae is lost and the
sender has to send it again
This concept is being improved using the Time-to-live
concept
21. Streams
• According to Prof. Tom Rodden of Univ of
Nottingham, 2.8 million mails are being sent per
second across the world.
• If Bitmessage is expected to store all these messages,
it has to implement some concept compared to the
normal block chain used by bitcoin
• For this, Bitmessage uses Streams.
• Streams are a way to self-segregate the messages
when the volume of the messages is too high
22. • When the volume of messages become too high, the
client can divide the block chain into child streams
• Problem: Inter stream messaging is not possible in
Bitmessage.
• If the receiver of the message is in a different stream,
the sender has to create an address in that other
stream in order to send the message.
23. Conclusion
• Bitmessage completely redesigns the email system
• It is completely anonymous
• There are a few issues that still exist such as Perfect
Forward Secrecy and the question of scalability
24. Future Work
• An MIT graduate has developed a new protocol
based on Bitmessage
• This message is called Bitmask or Bitmessage 2.0.
This protocol uses bandwidth based metrics instead
of proof of work
• A protocol called LibertyMail is being developed
which is again based on Bitmessage system
25. Idea
• Currently, Bitmessage, like bitcoin in the beginning
has only one client, Bitmessage-Qt
• This is a standalone client in the system which is
used independent of any mail client
• The problem with this kind of client is that it
downloads all the block chain into the individual
system
• While this is a hindrance only when downloading
the client for the first time, it is still a hindrance
26. • Bitcoin overcomes this hindrance by using a thin
client based architecture
• Electrum is an example
• Electrum has its multiple servers located across the
world.
• A person who wants to use a bitcoin client can
generate the keys on his local machine and send it to
the electrum server which posts it onto the block
chain
27. • Electrum uses passphrase based electrum client that
creates deterministic addresses based on the seed
value.
• The idea of my project is to use a similar
architecture in Bitmessage.
• Using this architecture, we can still mask the
metadata
