What academia calls 'overkill' actually comes nearer true security

What academia calls 'overkill' actually comes nearer true security. CypherSaber was 'found' to be 'potentially insecure' by 'academia.' Double or triple the rounds and their attacks become worthless. Run 500 rounds and it becomes priceless protection. These birds in academia squawk about 'CPU cycles' being a paramount consideration in cryptography. Meanwhile computers are a thousand times more powerful than when minimal CPU cycles were important. I could have 100 rounds of AES or CypherSaber with 100 keys for every email coming into my computer and the computer wouldn't even break a sweat. B..bb...bbb... but... It's not viable for microcontrollers and small devices... How many people do you know that read their emails on microcontrollers and small devices? So who cares about CPU cycles? It's a red herring to keep crypto weak. Ideally I want cryptography that makes my computer lag just a tiny little bit. If it makes my computer just a little hesitant, then I know the attacker with a supercomputer has a tough nut to crack.

I think in evaluating the strength of a cryptosystem you're looking at the effort ratio between attack and defense. What you're suggesting is take a weak system and multiply both terms of the ratio by 100, or 500. This does not make it any stronger. Also, most mobile users read their emails on microcontrollers or small devices, no?

> What you're suggesting is take a weak system and multiply both terms of the ratio by 100, or 500. This does not make it any stronger. This statement is nonsense, and it attributes to me words I did not write. You're attacking a scarecrow. Ever heard of "triple DES?" That's broken DES, run three times, and voila, approved as secure. Ditto for CipherSaber. This has been done with algorithms as attacks were found for a limited number of rounds, they just increase the number of rounds and keep using the algorithm. That has been a common practice for decades. Many well-designed symmetric ciphers gain security with extra rounds. It is known that increasing the rounds in CipherSaber increases its security. > Also, most mobile users read their emails on microcontrollers or small devices, no? you mean a quadcore arm? that's hardly a microcontroller. microcontrollers means little boards and chips in custom applications. androids and iphones can handle plenty of crypto and they are not microcontrollers. the chipset in your router or modem, or in your radio antenna might be a microcontroller.

> This statement is nonsense, and it attributes to me words I did not write. You're attacking a scarecrow. Ever heard of "triple DES?" That's broken DES, run three times, and voila, approved as secure. Triple DES is not simply DES "run three times". It's run three times **with three different keys**. This is essential. - original DES: 56-bit key - triple DES: 168-bit key (56 bits for each round) Extrapolating, for a theoretical 100-round DES you would need a 5600-bit key. At that stage, you're better off with OTP's. Same for any other algorithm. To obtain an actual improvement in strength, you need to throw in new key material for each round, which is only practical in small amounts.

Double or CypherSaber was found to be potentially insecure by academia: calls overkill actually comes nearer true security. Run rounds and the computer and the rounds and the rounds and small devices? Bb?

That's why I just use this key for everything: 111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111

Is this ASCII or HEX?

ASCII, obviously. 160-bit, 1-filled.
