Today’s state of the art mobile phone infrastructure like GSM or UMTS impose serious security issues. Their design is not intended to support end-to-end encryption while several flaws have been disclosed lately. For instance, GSM Wiretapping can be performed with cheap off-the-shelf hardware by everyone with extended technical knowledge.

Off-the-Record (OTR) Messaging allows you to have private conversations over instant messaging by providing:
- Encryption – No one else can read your instant messages.
- Authentication – You are assured the correspondent is who you think it is.
- Deniability – The messages you send do not have digital signatures that are checkable by a third party. Anyone can forge messages after a conversation to make them look like they came from you. However, during a conversation, your correspondent is assured the messages he sees are authentic and unmodified.
- Perfect forward secrecy – If you lose control of your private keys, no previous conversation is compromised
