Attacks on S/MIME and OpenPGP,atically exploited in the EFAIL attacks: The malleability of the symmetric encryption modes was used to construct .. The MIME entity-centered processing in MIME and S/MIME was exploited to build .. The complex signature verification process of S/MIME and OpenPGP was broken at several levels, except for the basic cryptographic operations.

Email: Protocols and SPAM,y features have been added to the SMTP, POP3, and IMAP protocols. An early form of machine learning is used to detect SPAM e-mails, and authentication schemes such as DKIM and SPF have been integrated into SMTP to distinguish legitimate e-mails from SPAM.

Resistance and the Fight against Repression,Data integrity can be protected using hash functions, message authentication codes, and digital signatures. These cryptographic mechanisms are introduced in this chapter, along with the combination of encryption and message authentication codes that results in authenticated encryption.

https://doi.org/10.1007/978-3-030-60421-9S/MIME is a standard to encrypt and digitally sign e-mails, which is fully compatible with the MIME data format. It uses PKCS#7/CMS as cryptographic data format. E-mails are sent using the SMTP protocol and retrieved using either POP3 or IMAP (chapter .). In this chapter, we will concentrate on e-mail data formats, starting with RFC 822.
